- FreeBSD/alpha Hardware Information
- ==================================
-
-This file is maintained by Wilko Bulte <wilko@freebsd.org>
-
-Additions, corrections and constructive criticism are invited. In
-particular information on system quirks is more than welcome.
-
-
-Overview
---------
-
-This document tries to provide a starting point for those who want to start
-running FreeBSD on an Alpha-based machine. It is aimed at providing
-background information on the various hardware designs. It is not a
-replacement for the systems manuals.
-
-The information is structured as follows:
-
-- general hardware requirements to run FreeBSD on Alpha.
-- system specific information for each of the systems/boards supported
- by FreeBSD/alpha.
-- information on expansion boards for FreeBSD/alpha, including things
- that differ from what is in the generic supported hardware list.
-
-Note: you will see references to DEC, Digital Equipment Corporation and
-Compaq used more or less interchangeably. Now that Compaq has acquired Digital
-Equipment it would be more correct to refer to Compaq-only.
-
-
-In general, what do you need to run FreeBSD/alpha?
---------------------------------------------------
-
-Obviously you will need an Alpha machine that FreeBSD/alpha knows about.
-Alpha machines are NOT like PCs. There are considerable differences
-between the various chip sets and mainboard designs. This means that a kernel
-needs to know the intimate details of a particular machine before it can run
-on it. Throwing some odd GENERIC kernel at unknown hardware is almost
-guaranteed to fail miserably.
-
-For a machine even to be considered for FreeBSD use please make sure it has
-the SRM console firmware installed. Or at least make sure that SRM console
-firmware is available for this particular machine type. If FreeBSD does not
-currently support your machine type, there is a good chance that this will
-change at some point in time, assuming SRM is available.
-
-Machines with the ARC or AlphaBIOS console firmware were intended for
-WindowsNT. Some of them have SRM firmware available in the system ROMs
-which you only have to select (via an ARC or AlphaBIOS menu). In other cases
-you will have to re-flash the ROMs with SRM code. Check on
-http://ftp.digital.com/pub/DEC/Alpha/firmware to see what is available
-for your particular system. In any case: no SRM -> no FreeBSD (or NetBSD,
-OpenBSD, Tru64 Unix or OpenVMS for that matter). With the demise of
-WindowsNT/alpha a lot of former NT boxes are sold on the second hand
-market. They have little or no trade-in value when they are NT-only from the
-console perspective. So, be suspicious if the price appears too good.
-
-Known non-SRM machines are:
- Digital XL series
- Digital XLT series
- Samsung PC164UX
- Samsung 164B
-
-To complicate things a bit further: Digital used to have so called
-'white-box' Alpha machines destined as NT-only and 'blue-box' Alpha machines
-destined for OpenVMS and Digital Unix. These names are based on the color
-of the cabinets, 'FrostWhite' and 'TopGunBlue' respectively.
-Although you could put the SRM console on the whitebox, OpenVMS and Digital
-Unix will refuse to boot on them. FreeBSD in post-4.0R will run on both the
-white and the blue-box variants. Before someone asks: the white ones had a
-rather different (read: cheaper) price tag.
-
-As part of the SRM you will get the so called OSF/1 PAL code (OSF/1 being the
-initial name of Digital's Unix offering on Alpha). The PAL code can be thought
-of as a software abstraction layer between the hardware and the operating
-system. It uses normal CPU instruction plus a handful of privileged
-instructions specific for PAL use. PAL is not microcode by the way.
-The ARC firmware contains a different PAL code, geared towards WinNT and in
-no way suitable for use by FreeBSD (or more generic: Unix or OpenVMS).
-Before someone asks: Linux/alpha brings its own PAL code, allowing it to
-boot on ARC & AlphaBIOS. There are various reasons why this is not a
-very good idea in the eyes of the *BSD folks. I don't want to go into
-details here.
-
-There is another pitfall ahead: you will need a disk adapter that the SRM
-console recognizes in order to be able to boot from your disk. What is
-acceptable to SRM as a boot adapter is unfortunately system and SRM version
-dependent. For older PCI based machines this means you will need either
-a NCR/Symbios 53C810 based adapter, or a Qlogic 1020/1040 based adapter.
-Some machines come with a SCSI chip embedded on the mainboard. Newer machine
-designs and SRM versions will be able to work with later SCSI chips/adapters.
-Check out the machine specific info below. Please note that the rest
-of this discussion only refers to Symbios chips, this is meant to include
-the older chips that still have NCR stamped on them. Symbios bought the NCR
-designs.
-
-The problem might bite those who have machines that started their lives as
-WinNT boxes. The ARC or AlphaBIOS knows about *other* adapter types that it
-can boot from than the SRM. For example you can boot from an Adaptec 2940UW
-with ARC but (generally) not with SRM. Some newer machine types have introduced
-Adaptec boot support. Please consult the machine specific section for details.
-
-Some adapters that cannot be booted from work fine for data-only disks.
-The differences between SRM and ARC could also get you pre-packaged
-IDE CDROMs and hard drives in some (former NT) systems.
-SRM versions exist (depends on the machine type) that can boot
-from IDE disks and CDROMs. Check the machine specific section for details.
-
-FreeBSD/alpha 4.0 and later can be booted from the distribution CDROM.
-Earlier versions needed booting from a 2-floppy set.
-
-If you don't have/want a local disk drive you can boot via the Ethernet.
-This assumes a Ethernet adapter/chip that is recognized by the SRM.
-Generally speaking this boils down to either a 21040 or 21142 or 21143
-based Ethernet interface. Older machines / SRM versions may not recognize
-the 21142 / 21143 Fast Ethernet chips, you are limited to using 10Mbit
-Ethernet for net booting those machines. Non-DEC cards based on said chips will
-generally (but are not guaranteed to) work. Note that Intel took over the
-21x4x chips when it bought Digital Semiconductor. So you might see an Intel
-logo on them these days. Recent machine designs have SRM support for
-Intel 8255x Ethernet chips.
-
-Alpha machines can be run with SRM on a graphics console or on
-a serial console. ARC can be run on a serial consoles if need be. VT100
-emulation with 8 bit controls should at least allow you to switch from
-ARC to SRM mode without having to install a graphics card first.
-
-If you want to run your Alpha without a monitor/graphics card
-just don't connect a keyboard/mouse to the machine. Instead hook
-up a serial terminal[emulator] to serial port #1. The SRM will
-talk 9600N81 to you. This can be really practical for debugging purposes.
-Beware: some/most (?) SRMs will also present you with a console prompt at
-serial port #2. The booting kernel, however, will display the boot messages
-on serial port #1 and will also put the console there. This can be extremely
-confusing.
-
-Most PCI based Alphas can use ordinary PC-type VGA cards. The SRM contains
-enough smarts to make that work. It does not, however, mean that each and
-every PCI VGA card out on the street will work in an Alpha machine. Things
-like S3 Trio64, Mach64, and Matrox Millennium generally work. Old ET4000
-based ISA cards have also worked for me. But ask around first before buying.
-Please note that TGA cards are not supported as FreeBSD console display cards.
-
-Most PCI devices from the PC-world will also work in FreeBSD/alpha PCI-based
-machines. Check the /sys/alpha/conf/GENERIC file for the latest word on
-this. Be careful to check the appropriate machine type's discussion
-in case you want to use PCI cards that have PCI bridge chips on them.
-In some cases you might encounter problems with PCI cards not handling
-PCI parity correctly. This can lead to panics. PCI parity checking can be
-disabled using the following SRM command: SET PCI_PARITY OFF. This is not
-a FreeBSD problem, all operating systems running on Alpha hardware will
-need this workaround.
-
-If your system (also) contains EISA expansion slots you will need to run
-the EISA Configuration Utility (ECU) after you have installed EISA cards
-or have upgraded your console firmware.
-
-Parallel ports that can be found on most Alpha machines are supported.
-
-For Alpha CPUs you will find multiple generations. The original Alpha
-design is the 21064. It was produced in a chip process called MOS4,
-chips made in this process are nicknamed EV4. Newer CPUs are 21164, 21264
-etc. You will see designations like EV4S, EV45, EV5, EV56, EV6, EV67.
-The EVs with double digit numbers are slightly improved versions. For example
-EV45 has an improved FPU and 16 kByte on-chip separate I & D caches compared
-to the EV4 on which it is based. Rule of thumb: the higher the digit
-immediately following 'EV' the more desirable (read: faster / more modern).
-
-For memory you want at least 32 Mbytes. I have had FreeBSD/alpha run on a
-16 Mbyte system but you will not like that. Kernel build times halved when
-going to 32 Mbytes. Note that the SRM steals 2Mbyte from the total system
-memory (and keeps it). For more serious use >= 64Mbyte is recommended.
-
-While on the subject of memory: pay close attention to the type of memory
-your machine uses. There are very different memory configurations and
-requirements for the various machines.
-
-Final word: I expect the above to sound a bit daunting to the first-time
-Alpha user. Don't be daunted too much. And do feel free to ask questions.
-
-
-System specific information
----------------------------
-
-Below is an overview of the hardware that FreeBSD/alpha runs on.
-This list will definitely grow, a look in /sys/alpha/conf/GENERIC
-can be enlightening. Alpha machines are often best known by their project
-code name. When known these are listed below in ().
-
-*
-* AXPpci33 ("NoName")
-*
-The NoName is a baby-AT mainboard based on the 21066 LCA (Low Cost Alpha)
-processor. It was originally designed for OEM-use. The LCA chip includes
-almost all of the logic to drive a PCI bus and the memory subsystem.
-All of this makes for a low-priced design.
-
-Due to the limited memory interface the system is not particularly
-fast in case of cache misses. As long as you stay inside the on-chip cache
-the CPU is comparable to a 21064 (first generation Alpha). These boards
-should be very cheap to obtain these days (even here in the Netherlands
-they were sold new for US$ 25).
-
-Features:
-- 21066 Alpha CPU at 166 MHz or 21066A CPU at 233MHz
- (21068 CPUs are also possible, but are even slower. Never seen/used one)
-- memory bus: 64 bits
-- on-board Bcache / L2 cache: 0, 256k or 1 Mbyte (uses DIL chips)
-- PS/2 mouse & keyboard port OR 5pin DIN keyboard (2 mainboard models)
-- memory: PS/2 style 72 pin 36 bit Fast Page Mode SIMMs,
- 70ns or better,
- installed in pairs of 2,
- 4 SIMM sockets
- uses ECC
-- 512kB Flash ROM for the console code.
-- 2x 16550A serial ports, 1x parallel port, floppy interface
-- 1x embedded IDE interface
-- expansion: 3 32 bit PCI slots (1 shared with ISA)
- 5 ISA slots (1 shared with PCI)
-- embedded Fast SCSI using a Symbios 53C810 chip
-
-SRM:
-NoNames can either have SRM *or* ARC console firmware in their Flash ROM.
-The Flash ROM is not big enough to hold both ARC and SRM at the same time
-and allow software selection of alternate console code. But you need
-SRM-only anyway.
-
-Cache:
-Cache for the NoNames are 15 or 20 ns DIL chips. For a 256 kByte cache you
-want to check your junked 486 mainboard. Chips for a 1 Mbyte cache are a rarer
-breed unfortunately. Getting at least a 256kByte cache is recommended
-performance wise. Cache-less they are really slow.
-
-Power:
-The NoName mainboard has a PC/AT-standard power connector. It also has
-a power connector for 3.3 Volts. No need to rush out to get
-a new power supply. The 3.3 Volts is only needed in case you run 3.3 Volts
-PCI expansion boards.
-
-IDE:
-The IDE interface is supported by FreeBSD and requires a line in the
-kernel configuration file as follows:
-
- device ata0 at isa? port IO_WD1 irq 14
-
-The SRM console unfortunately cannot boot from IDE disks.
-
-Memory:
-Make sure you use true 36 bit SIMMs, and only FPM (Fast Page Mode). EDO RAM
-or SIMMs with fake parity *will not work* (the board uses the 4 extra bits
-for ECC!). 33 bit FPM SIMMs will for the same reason not work either.
-
-Keyboard/mouse:
-Given the choice, get the PS/2-variant mainboard. Apart from giving you a
-mouse port as bonus it is directly supported by Tru64 Unix in case you ever
-want/need to run it. The "DIN-plug"-variant should work OK for FreeBSD.
-
-The OEM manual is recommended reading.
-See ftp://ftp.digital.com/pub/DEC/axppci/design_guide.ps
-
-The kernel configuration file for a NoName kernel must contain:
- options DEC_AXPPCI_33
- cpu EV4
-
-
-*
-* Universal Desktop Box (UDB or "Multia")
-*
-
-Note: Multia can be either Intel or Alpha CPU based. We assume Alpha based
- ones here for obvious reasons.
-
-Multia is a small desktop box intended as a sort of personal workstation.
-They come in a considerable number of variations, check closely what you
-get.
-
-Features:
-- 21066 Alpha CPU at 166 MHz or 21066A CPU at 233MHz
-- memory bus: 64 bits
-- on-board Bcache / L2 cache: COAST-like 256 kByte cache module
- 233MHz models have 512kByte of cache
- 166MHz models have soldered-on 256kB caches
-- PS/2 mouse & keyboard port
-- memory: PS/2 style 72 pin 36 bit Fast Page Mode SIMMs,
- 70ns or better,
- installed in pairs of 2,
- 4 SIMM sockets
- uses ECC
-- 2x 16550A serial ports, 1x parallel port, floppy interface
-- Intel 82378ZB PCI to ISA bridge
-- 1x embedded 21040 based 10Mbit Ethernet, AUI or 10base2 connector
-- expansion: 1 32 bit PCI slot, 2 PCMCIA slots
-- on-board Crystal CS4231 or AD1848 sound chip
-- embedded Fast SCSI using a Symbios 53C810 chip on the PCI riser card
-
-SRM/ARC:
-Multia has enough Flash ROM to store both SRM and ARC code at the same time
-and allow software selection of one of them.
-
-Expansion:
-Multia has only one 32 bit PCI slot for expansion, and it is only
-suitable for a small form factor PCI card too. In sacrificing the PCI slot
-space you can mount a 3.5" hard disk drive. Mounting stuff may have come
-with your Multia. Adding a 3.5" disk is not a recommended upgrade due to
-the limited power rating of the power supply and the extremely marginal
-cooling of the system box. Don't!
-
-Multia also has 2 PCMCIA expansion slots. These are currently unsupported.
-
-CPU:
-The CPU might or might not be socketed, check before considering CPU upgrade
-hacks. The low-end Multias have a soldered-in CPU.
-
-Graphics:
-It comes with a TGA based graphics on-board. Which is not suitable for
-console use with FreeBSD. Which means you will have to run it using a
-serial console. Note that the boot of the installation disk will appear
-to work fine using the TGA console, but then switches to using the
-serial port. This is even mentioned during by installer (but never read
-by the human doing the install..). Your keyboard appears dead from that point
-on.
-
-Serial:
-Multia has 2 serial ports but routes both of them to the outside world
-on a single 25 pin sub-D connector. The Multia FAQ explains how to
-build your own Y-cable to allow both ports to be used.
-
-Floppy:
-Although the Multia SRM supports booting from floppy this is problematic.
-Typical errors look like "*** Soft Error - Error #10 - FDC: Data overrun or
-underrun". This is not a FreeBSD problem, it is a SRM problem. The best
-available workaround to install FreeBSD is to boot from a SCSI CDROM.
-
-Sound:
-Works fine using pcm driver and a line in the kernel configuration file as
-follows for the Crystal CS4231 chip:
-
- device pcm0 at isa? port 0x530 irq 9 drq 3 flags 0x15
-
-I have not yet been successful in getting my Multia with the AD1848 to
-play any sound.
-
-While verifying playback I was reminded of the lack of CPU power of the 166MHz
-CPU: MP3 only plays acceptable using 22kHz down-sampling.
-
-Hot:
-Multias are somewhat notorious for dying of heat strokes. The very compact
-box does not really allow cooling air access very well. Please use the
-Multia on its vertical stand, don't put it horizontally ('pizza style').
-Replacing the fan with something which pushes around more air is
-recommended. Beware of PCI cards with high power consumption.
-If your system has died you might want to check on the Multia-Heat-Death
-pages at the NetBSD web-site http://www.netbsd.org
-
-IDE:
-The Intel 82378ZB PCI to ISA bridge enables the use of an IDE disk. This
-requires a line in the kernel configuration file as follows:
-
- device ata0 at isa? port IO_WD1 irq 14
-
-The IDE connector pin spacing is thought for 2.5" laptop disks. A 3.5"
-IDE disk would not fit in the case anyway. At least not without sacrificing
-your only PCI slot.
-
-The SRM console does not know how to boot from IDE disks unfortunately.
-
-SCSI:
-In case you want to change the internal hard drive: the internal flat cable
-running from the PCI riser board to the 2.5" (!!) hard drive has a finer pitch
-than the standard SCSI flat cables. Otherwise it would not fit on the 2.5"
-drives. There are also riser cards that have a standard-pitch SCSI cable
-attached to it, which will fit an ordinary SCSI disk.
-
-Again, I recommend against trying to cram a replacement hard disk inside. Use
-the external SCSI connector and put your disk in an external enclosure.
-Multias run hot enough as-is. In most cases you will have the external high
-density 50pin SCSI connector but some Multia models came without disk and
-may lack the connector. Something to check before buying one.
-
-The kernel configuration file for a Multia kernel must contain:
- options DEC_AXPPCI_33
- cpu EV4
-
-More info:
-Recommended reading on Multia can be found at

-
-*
-* Personal Workstation ("Miata")
-*
-
-The Miata is a small tower machine intended to be put under a desk. There
-are multiple Miata variants. The original Miata is the MX5 model. Because
-it suffers from a number of hardware design flaws a redesign was performed,
-yielding the MiataGL. Unfortunately the boxes are quite indistinguishable.
-An easy check is to see if the back of the machine sports two
-USB connectors. If yes, it is a MiataGL.
-
-System designations look like "Personal Workstation 433a". Personal
-Workstation, being a bit of a mouthful, is often abbreviated to PWS.
-This means it has a 433 MHz CPU, and started life as a WinNT workstation
-(the trailing 'a'). Systems designated from day 1 to run Tru64
-Unix or OpenVMS will sport '433au'. WinNT-Miatas are likely
-to come pre-configured with an IDE CDROM drive. So, in general systems
-are named like PWS[433,500,600]a[u].
-
-There was also a Miata model with a special CPU cooling system by Kryotech.
-That one has a different enclosure.
-
-Features:
-
-- 21164A EV56 Alpha CPU, at 433, 500 or 600MHz
-- 21174 Core Logic ("Pyxis") chip set
-- on-board Bcache / L3 cache: 0, 2 or 4 Mbytes (uses a cache module)
-- memory bus: 128 bits wide, ECC protected
-- memory: Miata uses unbuffered SDRAMs,
- installed in pairs of 2,
- 6 DIMM sockets
- 1.5 Gbytes max
-- on-board Fast Ethernet based on:
- - MX5 uses a 21142 or 21143 Ethernet chip dependent on the version of the
- PCI riser card
- - MiataGL has a 21143 chip
- - the bulkhead can be 10/100 UTP, or 10 UTP/BNC
-- 2x on-board [E]IDE based on:
- - MX5: CMD646
- - MiataGL: Cypress 82C693
-- 1x Ultra-Wide SCSI Qlogic 1040 [MiataGL only]
-- expansion: 2 64-bit PCI slots
- 3 32-bit PCI slots (behind a DEC PCI-PCI bridge chip)
- 3 ISA slots (physically shared with the 32 bit PCI slots, via
- an Intel 82378IB PCI to ISA bridge chip)
-- 2x 16550A serial port
-- 1x parallel port
-- PS/2 keyboard & mouse port
-- USB interface [MiataGL only]
-- embedded sound based on an ESS1888 chip
-
-CPU mainboard and PCI 'riser' board:
-The Miata logic is divided into two printed circuit boards.
-The lower board in the bottom of the machine has the PCI
-and ISA slots and things like the sound chip etc. The top board
-has the CPU, the Pyxis chip, memory etc. Note that MX5 and the MiataGL use
-a different PCI riser board. This means that you cannot just upgrade to
-a MiataGL CPU board (with the newer Pyxis chip) but that you will also need
-a different riser board. Apparently an MX5 riser with a MiataGL CPU board
-will work but it is definitely not a supported or tested configuration.
-Everything else (cabinet, wiring etc etc) is identical for MX5 and MiataGL.
-
-DMA bug:
-MX5 has problems with DMA via the 2 64-bit PCI slots when this DMA
-crosses a page boundary. The 32 bit slots don't have this problem because the
-PCI-PCI bridge chip does not allow the offending transfers. The SRM code
-knows about the problem and refuses to start the system if there is a PCI
-card in one of the 64bit slots that it does not know about. Cards that are
-'known good' to the SRM are allowed to be used in the 64bit slots.
-
-If you want to fool the SRM you can type "set pci_device_override" at
-the SRM prompt. Just don't complain if your data mysteriously gets mangled.
-
-The complete command is:
-
- set pci_device_override <vendor_id><device_id>
- e.g. set pci_device_override 88c15333
-
-A more radical approach is to use:
-
- set pci_device_override -1
-
-This disables PCI ID checking altogether, so that you can stick in any
-random PCI card without its ID getting checked. For this to work you need
-a sufficiently new SRM in your Miata. Again: do this on your own
-risk.
-
-The kernel reports it when it sees a buggy Pyxis chip:
-Sep 16 18:39:43 miata /kernel: cia0: Pyxis, pass 1
-Sep 16 18:39:43 miata /kernel: cia0: extended capabilities: 1<BWEN>
-Sep 16 18:39:43 miata /kernel: cia0: WARNING: Pyxis pass 1 DMA bug; no
-bets...
-
-A MiataGL probes as:
-Jan 3 12:22:32 miata /kernel: cia0: Pyxis, pass 1
-Jan 3 12:22:32 miata /kernel: cia0: extended capabilities: 1<BWEN>
-Jan 3 12:22:32 miata /kernel: pcib0: <2117x PCI host bus adapter> on cia0
-
-MiataGL does not have the DMA problems of the MX5. PCI cards that make
-the MX5 SRM choke when installed in the 64bit slots are accepted without
-problems by the MiataGL SRM.
-
-The latest mainboard revisions of MX5 contain a hardware workaround for the
-bug. The SRM does not know about the ECO and will complain about unknown cards
-as before. So does the FreeBSD kernel by the way.
-
-EIDE:
-The Miata SRM can boot from IDE CDROM drives. Hard disk boot is known to work
-for both MiataGL and MX5 disks, so you can root FreeBSD from an IDE disk. Speeds
-on MX5 are around 14 Mbytes/sec assuming a suitable drive. The CMD646 chip will
-support up to WDMA2 mode as the silicon is too buggy for use with UDMA.
-
-PCI-PCI bridge:
-The MiataGL has a faster PCI-PCI bridge chip on the PCI riser card than
-some of the MX5 riser card versions. Some of the MX5 risers have the *same*
-chip as the MiataGL. All in all there is a lot of variation.
-
-Not all VGA cards will work behind the PCI-PCI bridge. This manifests itself
-as no video at all. Workaround is to put the VGA card 'before' the bridge,
-in one of the 64 bit PCI slots.
-
-Sound:
-Both MX5 and MiataGL have an on-board sound chip, an ESS1888. It emulates
-a SoundBlaster and can be enabled by putting
-
- device pcm0
- device sbc0
-
-in your kernel configuration file.
-
-Cache:
-in case your Miata has the optional cache board installed make sure
-it is firmly seated. A slightly loose cache has been observed to cause
-weird crashes (not surprising obviously, but maybe not so obvious when
-troubleshooting). The cache module is identical between MX5 and MiataGL.
-
-Installing a 2Mb cache module achieves, apart from a 10-15% speed increase
-(based on buildworld elapsed time), a *decrease* for PCI DMA read bandwidth
-from 64bit PCI cards. A benchmark on a 64-bit Myrinet card resulted in
-a decrease from 149 Mbytes/sec to 115 Mbytes/sec. Something to keep in
-mind when doing really high speed things with 64 bit PCI adapters.
-
-Keyboard:
-If you experience SRM errors like "ERROR: scancode 0xa3 not supported
-on PCXAL" after halting FreeBSD you should update your SRM firmware
-to V7.2-1 or later. This SRM version is first available on the Firmware
-Update CD V5.7, or on http://www.compaq.com The problem is fixed on both
-Miata MX5 and Miata GL.
-
-USB:
-Supported by FreeBSD 4.1 and later.
-
-Power:
-Disconnect the power cord before dismantling the machine, the soft-power
-switch keeps part of the logic powered even when the machine is switched
-off.
-
-The kernel configuration file for a Miata kernel must contain:
- options DEC_ST550
- cpu EV5
-
-*
-* DEC3000 family (the "Bird" machines)
-*
-
-The DEC3000 series were among the first Alpha machines ever produced. They
-are based on an I/O bus called the Turbo Channel (TC) bus. These
-machines are built like tanks (watch your back).
-
-DEC3000 can be subdivided in DEC3000/500-class and DEC3000/300-class.
-The DEC3000/500-class is the early high-end workstation/server Alpha family.
-Servers use serial consoles, workstations have graphics tubes.
-DEC3000/300-class is the lower-cost workstation class.
-
-DEC3000/500-class are quite fast (considering their age) thanks to the
-good memory design. DEC3000/300 is crippled compared to DEC3000/500 because
-of its much narrower memory bus.
-
-They are called 'Birds' because their internal DEC code names were bird
-names:

-- 8 bit graphics on-board [some models] or via a TC card [some other models]
-
-SCSI:
-Currently DEC3000 machines can only be used diskless on FreeBSD/alpha. The
-reason for this is that the SCSI drivers needed for the TC SCSI adapters
-were not brought into CAM that the recent FreeBSD versions use. TC option
-cards for single (PMAZ-A) or dual fast SCSI (PMAZC-AA) are also available.
-And currently have no drivers on FreeBSD either.
-
-DEC3000/300 has 5Mbytes/sec SCSI on-board. This bus is used for both internal
-and external devices. DEC3000/500 has 2 SCSI buses. One is for internal
-devices only, the other one is for external devices only.
-
-Floppy devices found in the DEC3000s are attached to the SCSI bus (via a
-bridge card). This makes it possible to boot from them using the same device
-names as ordinary SCSI hard-disks (>>> BOOT DKA300 for example).
-
-Expansion:
-The 3000/300 series has a half-speed TurboChannel compared to the other
-3000 machines. Some TC expansion cards have troubles with the half-speed
-bus. Caveat emptor.
-
-ISDN interface:
-ISDN does not work on FreeBSD.
-
-Memory:
-DEC3000/300-class uses standard 36 bit, 72 pin Fast Page Mode SIMMs.
-EDO SIMMs, 32 or 33 bit SIMMs all will not work in Pelicans.
-For 32Mbyte SIMMs to work on the DEC3000/300-class the presence detect
-bits/pins of the SIMM must correspond to what the machine expects. If they
-don't, the SIMM is 'seen' as a 8 Mbyte SIMM. 8 Mbyte and 32 Mbyte SIMMs can
-be mixed, as long as the pairs themselves are identical.
-
-When you find yourself in need of fixing 32Mbyte SIMMs that lack correct
-presence bits the following info might be of use:
-
-There are four presence detection bits on PS/2 SIMMs. Two of
-the bits indicate the access time. The other two indicate the memory size.
-
-At one end of the SIMM there are two rows of four solder pads. One
-row is connected to Vss (GND) and the other is connected to pins
-67 (PRD1), 68 (PRD2), 69 (PRD3), 70 (PRD4).
-
-If you bridge a pair of pads with a small resistor or a drop of
-solder you ground that particular bit.
-
- PRD1 PRD2 mem. size
- -----------------------------
- GND GND 4 or 64 Mbyte
- Open GND 2 or 32 Mbyte
- GND Open 1 or 16 Mbyte
- Open Open 8 Mbyte
-
- PRD3 PRD4 access time
- ------------------------------
- GND GND 50 or 100 nsec
- Open GND 80 nsec
- GND Open 70 nsec
- Open Open 60 nsec
-
-DEC3000/500-class can use 2, 4, 8, 16 and 32 Mbyte 100pin SIMMs.
-Note that the maximum memory size varies from system to system,
-desktop machines have sacrificed box size for less memory SIMM sockets.
-Given enough sockets and enough SIMMs you can get to 512 Mbytes maximum.
-This is one of the main differences between floor standing and desktop
-machines, the latter have far less SIMM sockets.
-
-Sound:
-The sound hardware is not supported on any of the Birds.
-
-Graphics:
-The is no X-Windows version available for the TC machines.
-DEC3000/300 needs a serial console. DEC3000/500-class might
-work with a graphical console. I ran mine with a serial console so I cannot
-verify this.
-
-Birds can be obtained from surplus sales etc. As they are not PCI
-based they are no longer actively maintained. TC expansion boards can
-be difficult to obtain these days and support for them is not too good
-unless you write/debug the code yourself. Programming information for TC
-boards is hard to find. Birds are recommended only if a. you can get them
-cheap and b. if you prepared to work on the code to support them better.
-
-For the DEC3000/[4-9]00 series machines the kernel config file must
-contain:
- options DEC_3000_500
- cpu EV4
-
-For the DEC3000/300 ("Pelican") machines the kernel config file must
-contain:
- options DEC_3000_300
- cpu EV4

-*
-*Evaluation Board 64plus ("EB64+"), Aspen Alpine
-*
-
-In its attempts to popularize the Alpha CPU DEC produced a number of so
-called Evaluation Boards. The EB64+ family boards have the following feature
-set:
-
-- 21064 or 21064A CPU, 150 to 275MHz
-- memory bus: 128 bit
-- memory: PS/2 style 72 pin 33 bit Fast Page Mode SIMMs,
- 70ns or better,
- installed in sets of 4
- 8 SIMM sockets
- uses parity
-- Bcache / L2 cache: 512 kByte, 1 Mbyte or 2 Mbytes
-- 21072 ("APECS") chip set
-- Intel 82378ZB PCI to ISA bridge chip ('Saturn')
-- dual 16550A serial ports
-- Symbios 53C810 Fast-SCSI
-- embedded 10 Mbit Ethernet
-- 2 PCI slots
-- 3 ISA slots
-
-Aspen Alpine:
-Aspen Alpine is slightly different, but is close enough to the EB64+ to
-run an EB64+ SRM EPROM (mine did..). The Aspen Alpine does not have
-an embedded Ethernet, has 3 instead of 2 PCI slots. It comes with 2 Mbytes
-of cache already soldered onto the mainboard. It has jumpers to select
-the use of 60, 70 or 80ns SIMM speeds.
-
-Memory:
-36 bits SIMMs work fine, 3 bits simply remain unused.
-
-SRM:
-The SRM console code is housed in an UV-erasable EPROM. No easy flash SRM
-upgrades for the EB64+ The latest SRM version available for EB64+ is quite
-ancient anyway.
-
-SCSI:
-The EB64+ SRM can boot both 53C810 and Qlogic1040 SCSI adapters. Pitfall for
-the Qlogic is that the firmware that is down-loaded by the SRM onto the
-Qlogic chip is very old. There are no updates for the EB64+ SRM available.
-So you are stuck with old Qlogic bits too. I have had quite some problems
-when I wanted to use Ultra-SCSI drives on the Alpine with Qlogic. The
-FreeBSD/alpha kernel can be compiled to include a much newer Qlogic firmware
-revision. This is not the default because it adds hundreds of kBytes worth
-of bloat to the kernel. In FreeBSD 4.1 and later the isp firmware is contained
-in a kernel loadable module. All of this might mean that you need to use a
-non-Qlogic adapter to boot from.
-
-For the EB64+ class machines the kernel config file must contain:
- options DEC_EB64PLUS
- cpu EV4
-
-*
-* Evaluation Board 164 ("EB164, PC164, PC164LX, PC164SX") family
-*
-
-EB164 is a newer design evaluation board, based on the 21164A CPU. This
-design has been used to 'spin off' multiple variations, some of which are
-used by OEM manufacturers/assembly shops. Samsung did its own PC164LX
-which has only 32 bit PCI, whereas the Digital variant has 64 bit PCI.
-
-Features:
-- 21164A, multiple speed variants [EB164, PC164, PC164LX]
- 21164PC [only on PC164SX]
-- 21174 (Alcor) chip set
-- Bcache / L3 cache: EB164 uses special cache-SIMMs
-- memory bus: 128 bit / 256 bit
-- memory: PS/2 style SIMMs in sets of 4 or 8,
- 36 bit, Fast Page Mode, uses ECC, [EB164 and PC164]
- SDRAM DIMMs in sets of 2, uses ECC [PC164SX and PC164LX]
-- dual 16550A serial ports
-- PS/2 style keyboard & mouse
-- floppy controller
-- parallel port
-- 32 bits PCI
-- 64 bits PCI [some models]
-- ISA slots via an Intel 82378ZB PCI to ISA bridge chip
-
-Memory:
-Using 8 SIMMs for a 256bit wide memory can yield interesting speedups over
-a 4 SIMM/128bit wide memory. Obviously all 8 SIMMs must be of the same type
-to make this work. The system must be explicitly setup to use the
-8 SIMM memory arrangement. You must have 8 SIMMs, 4 SIMMs distributed
-over 2 banks does not work.
-
-SCSI:
-The SRM can boot from Qlogic 10xx boards or the Symbios 53C810[A].
-
-Newer Symbios 810 revisions like the Symbios 810AE are not recognized by
-the SRM on PC164. PC164 SRM does not appear to recognize a Symbios 53C895
-based host adapter (tested with a Tekram DC-390U2W). On the other hand
-some no-name Symbios 53C985 board has been reported to work.
-
-Cards like the Tekram DC-390F (Symbios875 based) have been confirmed to
-work fine on the PC164. Unfortunately this seems to be dependent on the
-actual version of the chip/board.
-
-Symbios 53C825[a] will also work as boot adapter. Diamond FirePort, although
-based on Symbios chips, is not bootable by the PC164SX SRM.
-PC164SX is reported to boot fine with Symbios825, Symbios875 and Symbios876
-based cards. In addition, Adaptec 2940U and 2940UW are reported to work for
-booting (verified on SRM V5.7-1). Adaptec 2930U2 and 2940U2[W] do not work.
-
-LX and SX with SRM firmware version 5.8 or later can boot from Adaptec
-2940-series adapters.
-
-In summary: this family of machines is 'blessed' with a challenging
-compatibility as far as SCSI adapters go.
-
-SRM quirks:
-PC164 the SRM sometimes seems to loose its variable settings.
-"For PC164, current superstition says that, to avoid losing settings,
-you want to first downgrade to SRM 4.x and then upgrade to a 5.x"
-One sample error that was observed was: "ERROR: ISA table corrupt!".
-A sequence of a downgrade to SRM4.9, an 'isacfg -init' and an 'init'
-made the problem go away. Some PC164 owners report they have never seen
-the problem.
-
-On PC164SX the AlphaBIOS allows you a selection to select 'SRM' to
-be used as console on the next power up. This selection does not appear to
-have any effect. In other words, you will get to the AlphaBIOS regardless
-of what you select. The fix is to reflash the console ROM with the SRM
-code for PC164SX. This will overwrite the AlphaBIOS and will get you the
-SRM console you desire. The SRM code can be found on the Compaq Web site.
-
-IDE:
-PC164 can boot from IDE disks assuming your SRM version is recent enough.
-
-Power:
-EB164 needs a power supply that supplies 3.3 Volts. PC164 does not implement
-the PS_ON signal that ATX power supplies need to switch on. A simple switch
-pulling this signal to ground fixes this problem.
-
-For the EB164 class machines the kernel config file must contain:
- options DEC_EB164
- cpu EV5
-

-* AlphaStation 200 ("Mustang") and 400 ("Avanti") series
-*
-
-The Digital AlphaStation 200 and 400 series systems are early PCI based
-workstations for the lower end. The 200 and 250 series is a desktop box, the
-400 series is a desk-side mini-tower.
-
-Features:
-- 21064 or 21064A CPU at speeds of 166 to 333 MHz
-- DECchip 21071-AA (core logic chip-set) consisting of:
- Cache/memory controller (one 21071-CA chip)
- PCI interface (one 21071-DA chip)
- Data path (two 21071-BA chips)
-- Bcache / L2 cache: 512 Kbytes (200 and 400 series)
- 2048KBytes (250 series)
-- memory bus: 64 bit
-- memory: 8 to 384 MBytes of RAM,
- 70 ns or better Fast Page DRAM,
- in three pairs (200 and 400 series)
- in two quads, so banks of four. (250 series)
- uses parity
-- PS/2 keyboard and mouse port
-- two 16550 serial ports
-- parallel port
-- floppy disk interface
-- 32 bit PCI expansion slots (3 for 400 series, 2 for 200 & 250 series)
-- ISA expansion slots (4 for 400 series, 2 for 200 & 250 series)
- (some ISA/PCI slots are physically shared)
-- embedded 21040-based Ethernet (200 & 250 series)

-- Intel 82378IB ("Saturn") PCI-ISA bridge chip
-- graphics is embedded TGA or PCI VGA (model dependent)
-- 16 bit sound (on 200 & 250 series)
-
-Memory:
-the system uses parity memory SIMMs, but it does not need 36 bit wide SIMMs.
-33 bit wide SIMMs are sufficient, 36 bit SIMMs are acceptable too. EDO or 32
-bit SIMMs will not work. 4, 8, 16, 32 and 64 Mbyte SIMMs are supported.
-
-Sound:
-The AS200 & AS250 sound hardware is reported to work OK assuming you have
-the following line in your kernel config file:
-
- device pcm0 at isa? port 0x530 irq 9 drq 0 flags 0x10011
-
-SCSI:
-AlphaStation 200 & 250 series has an automatic SCSI terminator. This means that
-as soon as you plug a cable onto the external SCSI connector the internal
-terminator of the system is disabled. It also means that you should not
-leave unterminated cables plugged into the machine.
-
-AlphaStation 400 series have an SRM variable that controls termination. In
-case you have external SCSI devices connected you must set this SRM
-variable using: "set control_scsi_term external". If only internal SCSI devices
-are present use: "set control_scsi_term internal"
-
-For the AlphaStation-[24][05]00 machines the kernel config file must contain:
- options DEC_2100_A50
- cpu EV4
-
-
-*
-* AlphaStation 500 and 600 ("Alcor" & "Maverick" for EV5, "Bret" for EV56)
-*
-AS500 and 600 were the high-end EV5 / PCI based workstations. EV6 based
-machines have in the meantime taken their place as front runners. AS500 is
-a desktop in a dark blue case (TopGun blue), AS600 is a sturdy desk-side box.
-AS600 has a nice LCD panel to observe the early stages of SRM startup.
-
-Features:

-
-SCSI:
-Early machines had Fast SCSI interfaces, later ones are Ultra SCSI capable.
-AS500 shares its single SCSI bus with internal and external devices. For a
-Fast SCSI bus you are limited to 1.8 meters bus length external to the box.
-+++ This is what some DEC docs suggest. Did they ever go Ultra?
-
-AS600 has one Qlogic chip dedicated to the internal devices whereas the
-other one is dedicated to external SCSI devices.
-
-Memory:
-In AS500 DIMMs are installed in sets of 4, in 'physically interleaved'
-layout. So, a bank of 4 DIMMs is *not* 4 adjacent DIMMs!
-
-In AS600 the memory SIMMs are placed onto two memory daughter cards. SIMMs
-are installed in sets of 8. Both memory daughter cards must be populated
-identical.
-
-PCI:
-AS600 has a peculiarity for its PCI slots. AS600 (or rather the PCI
-expansion card containing the SCSI adapters) does not allow I/O port
-mapping, therefore all devices behind it must use memory mapping.
-If you have problems getting the SCSI adapters to work, add the following
-option to /boot/loader.rc:
-
- set isp_mem_map=0xff
-
-This may need to be typed at the boot loader prompt before booting the
-installation kernel.
-
-For the AlphaStation-[56]00 machines the kernel config file must contain:
- options DEC_KN20AA
- cpu EV5
-
-*
-* AlphaServer 1000 ("Mikasa"), 1000A ("Noritake") and 800
-*
-The AlphaServer 1000 and 800 range of machines is aimed as departmental servers.
-They come in quite some variations in packaging and mainboard/cpu. Generally
-speaking there are 21064 (EV4) CPU based machines and 21164 (EV5) based
-ones. The CPU is on a daughter card, and the type of CPU (EV4 or EV5) must
-match the mainboard in use. AlphaServer 800 is a much smaller mini tower
-case, it lacks the StorageWorks SCSI hot-plug chassis. The main difference
-between AS1000 and AS1000A is that AS1000A has 7 PCI slots whereas AS1000
-only has 3 PCI slots and has EISA slots instead. AS800 with an EV5/400 MHz
-CPU was later re-branded as a DIGITAL Server 3300[R], AS800 with an EV5/500 MHz
-CPU was later re-branded as a DIGITAL Server 3305[R].
-
-Features:
-- 21064 EV4[5] CPU at 200, 233 or 266 MHz
- 21164 EV5[6] CPU at 300, 333 or 400 MHz (or 500 MHz for AS800 only)
-- cache:
-- memory bus: 128 bit with ECC
-- memory:
- AS1000[A]-systems:
- Use 72pin 36 bit Fast Page Mode SIMMs, 70ns or better
- 16 or 20 SIMM slots
- max memory is 1 Gb
- uses ECC
- AS800:
- Uses ECC EDO DIMMs.
-- embedded VGA (on some mainboard models)
-- expansion:
- 3 PCI, 2 EISA, 1 64-bit PCI/EISA combo (AS800)
- 7 PCI, 2 EISA (AS1000A)
- 2 PCI, 1 EISA/PCI, 7 EISA (AS1000)
-- embedded SCSI based on Symbios 810 [AS1000] or Qlogic 1020 [AS1000A]
-
-Box:
-AS1000 based machines come in multiple boxes. Floor standing, rack-mount,
-with or without StorageWorks SCSI chassis etc. The electronics are the
-same.
-
-Memory:
- AS1000-systems:
- All EV4 based machines use standard PS/2 style 36 bit 72pin SIMMs in sets
- of 5. The fifth SIMM is used for ECC.
- All EV5 based machines use standard PS/2 style 36 bit 72pin SIMMs in sets
- of 4. The ECC is done based on the 4 extra bits per SIMM (4 bits out of 36).
- The EV5 mainboards have 16 SIMM slots, the EV4 mainboards have 20 slots.
-
- AS800:
- Uses DIMMs in sets of 4. DIMM installation must start in slots marked
- bank 0. A bank is four physically adjacent slots. The biggest size DIMMs
- must be installed in bank 0 in case 2 banks of different DIMM sizes are
- used. Max memory size is 2Gb. Note that these are EDO DIMMs, not SDRAM.
-
-Console:
-The AS1000/800 are somewhat stubborn when it comes to serial
-consoles. They need >>> SET CONSOLE SERIAL before they go for
-a serial console. Pulling the keyboard from the machine is not sufficient,
-like it is on most other Alpha models. Going back to a graphical console
-needs >>> SET CONSOLE GRAPHICS at the serial console.
-
-SCSI:
-For AS800 you want to check if your Ultra-Wide SCSI is indeed in Ultra mode.
-This can be done using the EEROMCFG.EXE utility that is on the Firmware
-Upgrade CDROM.
-
-For the AlphaServer1000/1000A/800 machines the kernel config file must contain:
- options DEC_1000A
- cpu EV4 # depends on the CPU model installed
- cpu EV5 # depends on the CPU model installed
-
-*
-* DS10/VS10/XP900 ("Webbrick") / XP1000 ("Monet") / DS10L ("Slate")
-*
-Webbrick and Monet are high performance workstations/servers based on the
-EV6 CPU and the Tsunami chipset. Tsunami is also used in much higher-end
-systems and as such has plenty of performance to offer. DS10, VS10 and XP900
-are different names for essentially the same system. The difference are the
-software and options that are supported. DS10L is a DS10 based machine in a 1U
-high rackmount enclosure. DS10L is intended for ISPs and for HPTC clusters
-(e.g. Beowulf).
-
-Monet has, by 1999 standards, *stunning* (the words of a satisfied
-user) memory and I/O system bandwidth.
-
-** Webbrick / Slate
-
-Features:
-- 21264 EV6 CPU at 466 MHz
-- L2 / Bcache: 2MB, ECC protected
-- memory bus: 128 bit via crossbar, 1.3GB/sec to memory
-- memory: industry standard 200 pin 83 MHz buffered ECC SDRAM DIMMs
- 4 DIMM slots (2 for DS10L)
- installed in pairs of 2
- max memory is 2 Gb (1Gb for DS10L)
-- 21271 Core Logic chipset ("Tsunami")
-- 2 on-board 21143 Fast Ethernet controllers
-- AcerLabs M5237 (Aladdin-V) USB controller
-- AcerLabs M1533 PCI-ISA bridge
-- AcerLabs Aladdin ATA-33 controller
-- embedded dual EIDE
-- expansion: 3 64-bit PCI slots
- 1 32-bit PCI slots
- DS10L has a single 64bit PCI slot
-- 2x 16550A serial ports
-- 1x parallel port
-- 2x USB
-- PS/2 keyboard & mouse port
-
-Power:
-The system has a smart power controller. This means that parts of the system
-remain powered when it is switched off (like an ATX-style PC power supply).
-Before servicing the machine remove the power cord.
-
-Case:
-Webbrick is shipped in a desktop-style case similar to the older 21164
-"Maverick" workstations but which offers much better access to
-components. If you intend to build a farm you can rackmount them in a 19"
-rack, they are 3U high. Slate is 1U high but has only one PCI slot.
-
-Memory:
-DS10 has 4 DIMM slots. DIMMs are installed as pairs. Please note that
-DIMM pairs are not installed in adjacent DIMM sockets but rather physically
-interleaved. DIMM sizes of 32, 64, 128, 256 and 512 Mbytes are supported.
-
-When 2 pairs of identical-sized DIMMs are installed DS10 will use memory
-interleaving for higher performance. DS10L, which has only 2 DIMM slots cannot
-do interleaving.
-
-SCSI:
-Starting with SRM firmware version 5.9 you can boot from Adaptec 2940-series
-adapters in addition to the usual set of Qlogic and Symbios/NCR adapters.
-
-EIDE:
-The base model comes with a FUJITSU 9.5GB ATA disk as its boot device.
-FreeBSD/alpha works just fine using EIDE disks on Webbrick. DS10 has 2 IDE
-interfaces on the mainboard.

-- graphics options: ELSA Gloria Synergy or DEC/Compaq PowerStorm 3D
- accelerator cards
-
-Case:
-Monet is housed in a mini-tower like enclosure quite similar to the Miata
-box.
-
-SCSI:
-The on-board Qlogic UW-SCSI chip supports up to 4 internal devices. There is
-no external connector for the on-board SCSI.
-
-Memory:
-For 500 MHz CPUs 83 MHz DIMMs will do. Compaq specifies PC100 DIMMs for
-all CPU speeds. DIMMs are installed in sets of 4, starting with the
-DIMM slots marked '0'. Memory capacity is max 4 Gb.
-DIMMs are installed 'physically interleaved', note the markings of the
-slots. Memory bandwidth of Monet is twice that of Webbrick. The DIMMs live
-on the CPU daughter-card. Note that the system uses ECC RAM so you need DIMMs
-with 72 bits (not the PC-class 64 bit DIMMs)
-
-EIDE:
-Is usable / bootable for system disk so FreeBSD can be rooted on an EIDE
-disk. Although the Cypress chip has potential for 2 EIDE channels Monet uses
-only one of them.
-
-USB:
-If you experience problems trying to use the USB interface please check if
-the SRM variable "usb_enable" is set to "on". You can change this by
-performing: "set usb_enable on" at the SRM >>> prompt.
-
-Expansion caveats:
-- Don't try to use Symbios-chip based SCSI adapters in the PCI slots
-connected to hose 1. There is a not-yet-found FreeBSD bug that prevents this
-from working correctly.
-- Not all VGA cards will work behind the PCI-PCI bridge (so in slots 4 & 5).
-Only cards that implement VGA-legacy addressing correctly will work. Workaround
-is to put the VGA card 'before' the bridge.
-
-Sound:
-The sound chip is not currently supported with FreeBSD. There is work in
-progress in this area.
-
-The kernel config file must contain:
- options DEC_ST6600
- cpu EV5
-
-Contrary to expectation there is no 'cpu EV6' defined for inclusion in the
-kernel config file. The 'cpu EV5' is mandatory to keep config(8) happy.

-** DS20/DS20E ("Goldrush"):
-
-Features:
-- 21264 EV6 CPU at 500 or 670 MHz
-- dual CPU capable machine
-- L2 / Bcache: 4 Mbytes per CPU
-- memory bus: dual 256 bit wide with crossbar switch
-- memory: SDRAM DIMMs
- installed in sets of 4
- uses ECC
- 16 DIMM slots
- max. 4Gb
-- 21271 Core Logic chip-set ("Tsunami")
-- embedded Adaptec ? Wide Ultra SCSI
-- expansion: 2 independent PCI buses, driven by high-speed I/O
- channels called 'hoses'
- 6 64-bit PCI slots (3 per hose)
- 1 ISA slot
-
-Console:
-DS20 needs >>> SET CONSOLE SERIAL before it goes for a serial console.
-Pulling the keyboard from the machine is not sufficient. Going back to a
-graphical console needs >>> SET CONSOLE GRAPHICS at the serial console.
-Confusing is the fact that you will get SRM console output on the graphics
-console with the console set to serial, but when FreeBSD boots it honors
-the CONSOLE variable setting and all the boot messages as well as the
-login prompt will go to the serial port.
-
-Case:
-DS20 is housed in a fat cube-like enclosure. The enclosure also
-contains a StorageWorks SCSI hot-swap shelf for a maximum of 7 3.5" SCSI
-devices. DS20E is a sleeker case, without the StorageWorks shelf.
-
-Embedded SCSI:
-The embedded Adaptec SCSI chip on DS20 is disabled and is therefore
-not usable under FreeBSD.
-
-Starting with SRM firmware version 5.9 you can boot from Adaptec 2940-series
-adapters in addition to the usual set of Qlogic and Symbios/NCR adapters.
-This unfortunately does not include the embedded Adaptec SCSI chips.
-
-Memory:
-If you are using banks of DIMMs of different sizes the biggest DIMMs should
-be installed in the DIMM slots marked '0' on the mainboard. The DIMM slots
-should be filled 'in order' so after bank 0 install in bank 1 and so on.
-
-Expansion:
-Don't try to use Symbios-chip based SCSI adapters in the PCI slots
-connected to hose 1. There is a not-yet-found FreeBSD bug that prevents this
-from working correctly. DS20 ships by default with a Symbios on hose 1 so you
-have to move this card before you can install/boot FreeBSD on it.

-* AlphaServer 2000 ("DemiSable"), 2100 ("Sable"), 2100A ("Lynx")
-*
-
-The AlphaServer 2[01]00 machines are aimed as departmental servers.
-This is medium iron, not a hobbyist system. These are multi-CPU machines,
-up to 2 CPUs (AS2000) or 4 CPUs (2100[A]) can be installed.
-Both floor-standing and 19" rackmount boxes exist. Rackmount variations have
-different numbers of I/O expansion slots, different max number of CPUs and
-different maximum memory size. Some of the boxes come with an integral
-StorageWorks shelf to house hot-swap SCSI disks. There was an upgrade program
-available to convert your Sable machine into a Lynx by swapping the
-I/O backplane (the C-bus backplane remains). CPU upgrades were available
-as well.
-
-Features:
-- 21064 EV4[5] CPU[s] at 200, 233, 275 MHz
-- 21164 EV5[6] CPU[s]s at 250, 300, 375, 400 MHz
-- cache: varies in size with the CPU model; 1, 4 or 8Mbyte per CPU
-- embedded floppy controller driving a 2.88 Mbytes drive
-- embedded 10Mbit 21040 Ethernet [AS2100 only]
-- 2 serial ports
-- 1 parallel port
-- PS/2 style keyboard & mouse port
-
-NOTE: Lynx support is currently flagged as experimental due to lack of
- testing / test hardware.
-
-CPU:
-The CPUs spec-ed as 200 MHz are in reality running at 190 MHz. Maximum
-number of CPUs is 4. All CPUs must be of the same type/speed.
-
-If any of the processors are ever marked as failed, they will
-remain marked as failed even after they have been replaced (or reseated)
-until you issue the command 'clear_error all' on the SRM console and
-power-cycle the machine. This may be true for other modules (IO and memory)
-as well, but it has not been verified.
-
-Memory:
-The machines use dedicated memory boards. These boards live on a 128 bit
-C-bus shared with the CPU boards. DemiSable supports up to 1Gb, Sable up
-to 2Gb. One of the memory bus slots can either hold a CPU or a memory card.
-A 4 CPU machine can have a maximum of 2 memory boards.
-
-Some memory board modules house SIMMs. These are called SIMM carriers.
-There are also memory modules that have soldered-on memory chips
-instead of SIMMs. These are called 'flat memory modules'.
-
-SIMM boards are used in sets of eight 72-pin 36 bit FPM memory of 70ns
-or faster. SIMM types supported are 1Mb x36 bit (4 Mbyte) and 4Mb x36
-bit (16 Mbyte). Each memory board can house 4 banks of SIMMs. SIMM
-sizes can not be mixed on a single memory board. The first memory
-module must be filled with SIMMs before starting to fill the next
-memory module. Note that the spacing between the slots is not that
-big, so make sure your SIMMs fit physically (before buying them..)
-
-Console:
-Both Lynx and Sable are somewhat stubborn when it comes to serial
-consoles. They need >>> SET CONSOLE SERIAL before they go for
-a serial console. Pulling the keyboard from the machine is not sufficient,
-like it is on most other Alpha models. Going back to a graphical console
-needs >>> SET CONSOLE GRAPHICS at the serial console. On Lynx keep the
-VGA card in one of the primary PCI slots.
-
-The machines are equipped with a small OCP (Operator Control Panel) LCD
-screen. On this screen the self-test messages are displayed during system
-initialization. You can put your own little text there by using the SRM:
->>> SET OCP_TEXT "FreeBSD"
-
-The SRM >>> SHOW FRU command produces an overview of your configuration
-with module serial numbers, hardware revisions and error log counts.
-
-Embedded SCSI:
-Both Sable, DemiSable and Lynx have Symbios 810 based Fast SCSI on-board.
-Check if it is set to Fast SCSI speed by >>> SHOW PKA0_FAST. If set to
-1 it is negotiating for Fast speeds. >>> SET PKA0_FAST 1 enables Fast
-speeds.
-
-Internal disk storage:
-AS2100[A] come equipped with a StorageWorks 7 slot SCSI cage. A second cage
-can be added inside the cabinet. AS2000 has a single 7 slot SCSI cage,
-which cannot be expanded with an additional one. Note that the slot
-locations in these cages map differently to SCSI IDs compared to the
-standard StorageWorks shelves. Slot IDs from top to bottom
-are 0, 4, 1, 5, 2, 6, 3 when using a single bus configuration. The cage
-can also be set to provide two independent SCSI buses. This is used for
-embedded RAID controllers like the KZPSC (Mylex DAC960). Slot ID assignments
-for split bus are, from top to bottom: 0A, 0B, 1A, 1B, 2A, 2B, 3A, 3B.
-Where A and B signify a SCSI bus. In a single bus configuration the
-terminator module on the back of the SCSI cage is on the TOP. The jumper
-module is on the BOTTOM. For split bus operation these two modules are
-reversed. The terminator can be distinguished from the jumper by noting the
-chips on the terminator. The jumper does not have any active components on
-it.
-
-Expansion:
-DemiSable has 7 EISA slots and 3 PCI slots. Sable has 8 EISA and 3 PCI
-slots. Lynx, being newer, has 8 PCI and 3 EISA slots. The Lynx PCI slots
-are grouped in sets of 4. The 4 PCI slots closest to the CPU/memory
-slots are the primary slots, so logically before the PCI bridge chip.
-Note that contrary to expectation the primary PCI slots are the highest
-numbered ones (PCI4 - PCI7).
-
-Make sure you run the EISA Configuration Utility (from floppy) when
-adding/change expansion cards in EISA slots or after upgrading your
-console firmware. This is done by inserting the ECU floppy and typing
-RUNECU at the SRM >>> prompt.
-
- NOTE: EISA slots are currently unsupported, but the Compaq Qvision
- EISA VGA adapter is treated as an ISA device. It therefore
- works OK as a console.
-
-A special Extended I/O module for use on the C-bus was planned-for.
-Whether they ever saw daylight is unknown. In any case FreeBSD has never
-been verified with an ExtIO module.
-
-Power:
-The machines can be equipped with redundant power supplies. Note that
-the enclosure is equipped with interlock switches that switch off power
-when the enclosure is opened. The system's cooling fans are speed
-controlled. When the machine has more than 2 CPUs and more than 1 memory
-board dual power supplies are mandatory.
-
-The kernel config file must contain:
- options DEC_2100_A500
- cpu EV4
- cpu EV5

-* AlphaServer 4100 ("Rawhide")
-*
-
-The AlphaServer 4100 machine is aimed as an enterprise server.
-Expect a 30" high pedestal cabinet or alternatively the same system box in a
-19" rack. This is medium iron, not a hobbyist system.
-These are multi-CPU machines, up to 4 CPUs can be in a single
-machine. Basic disk storage is housed in one or two StorageWorks shelves
-at the bottom of the pedestal. The Rawhides intended for the NT market are
-designated DIGITAL Server 7300 (5/400 CPU), DIGITAL Server 7305 (5/533 CPU).
-A trailing R on the part-number means a rackmount variant.
-
-Features:
-- 21164 EV5 CPUs at 266, 300 MHz
- 21164A EV56 CPUs at 400, 466, 533, 600 and 666 Mhz
-- cache: 4 Mbytes per CPU (EV5 300 MHz was also available cache-less)
- 8 Mbytes (EV5 600Mhz only)
-- memory bus: 128 bit with ECC
-- embedded floppy controller
-- 2 serial ports
-- 1 parallel port
-- PS/2 style keyboard & mouse port
-
-Memory:
-Rawhide uses a maximum of 8 RAM modules. These modules are used in pairs
-and supply 72 bits to the bus (this includes ECC bits). Memory can be EDO
-RAM or synchronous DRAM. A fully populated Rawhide has 4 pairs of memory
-modules. Given the choice use SDRAM for best performance. The highest
-capacity memory board must be in memory slot 0. A mix of memory board sizes
-is allowed. A mix of EDO and SDRAM is also reported as working (assuming you
-don't try to mix EDO and SDRAM in one module pair).
-
-Embedded SCSI:
-Rawhide has an embedded Symbios 810 Fast SCSI bus.
-
-Expansion:
-Rawhides are available with a 8 64-bit PCI / 3 EISA slot expansion backplanes
-(called 'Saddle' modules). There are 2 separate PCI buses, PCI0 and PCI1.
-PCI0 has 1 dedicated PCI slot and (shared) 3 PCI/EISA slots. PCI0 also has a
-PCI/EISA bridge that drives things like the serial and parallel ports,
-keyboard/mouse etc. PCI1 has 4 PCI slots and an Symbios 810 SCSI chip. VGA
-console cards must be installed in a slot connected to PCI0.
-
-The current implementation has problems in handling PCI bridges. There is
-currently a limited fix in place which allows for single level, single device
-PCI bridges. The fix allows for the Digital supplied Qlogic SCSI card which
-sits behind a 21054 PCI bridge chip.
-
- NOTE: EISA slots are currently unsupported, but the Compaq Qvision
- EISA VGA adapter is treated as an ISA device. It therefore
- works OK as a console.
-
-Power:
-The system employs an I2C based power controller system. If you want to be
-sure all power is removed from the system pull the mains cables from the
-system.

-* AlphaServer 1200 ("Tincup") and AlphaStation 1200 ("DaVinci")
-*
-
-The AlphaServer 1200 machine is the successor to the AlphaServer 1000A.
-It uses the same enclosure the 1000A uses, but the logic is based on the
-AlphaServer 4000 design. These are multi-CPU machines, up to 2 CPUs can
-be in a single machine. Basic disk storage is housed in a StorageWorks shelves
-The AS1200 intended for the NT market are designated DIGITAL Server 5300
-(5/400 CPU) and DIGITAL Server 5305 (5/533 CPU).
-
-Features:
-- 21164A EV56 CPUs at 400 or 533 Mhz
-- cache: 4 Mbytes per CPU
-- memory bus: 128 bit with ECC
- DIMM memory on two memory daughter boards
-- embedded floppy controller
-- 2 serial ports
-- 1 parallel port
-- PS/2 style keyboard & mouse port
-
-Memory:
-AS1200 uses 2 memory daughter cards. On each of these cards are 8 DIMM slots.
-DIMMs must be installed in pairs. The maximum memory size is 4 Gbytes.
-Slots must be filled in order and slot 0 must contain the largest size
-DIMM if different sized DIMMs are used. AS1200 employs fixed starting
-addresses for DIMMs, each DIMM pair starts at a 512 Mbyte boundary.
-This means that if DIMMs smaller than 256 Mbyte are used the system's
-physical memory map will contain 'holes'. Supported DIMM sizes are 64 Mbytes
-and 256 Mbytes. The DIMMs are 72 bit SDRAM based, as the system employs ECC.
-
-Embedded SCSI:
-AS1200 has an embedded Symbios 810 Fast SCSI bus.
-
-Expansion:
-AS1200 has 5 64-bit PCI slots, one 1 32-bit PCI slot and one EISA slot
-(which is physically shared with one of the 64-bit PCI slots).
-There are 2 separate PCI buses, PCI0 and PCI1. PCI0 has the 32-bit PCI
-slot and the 2 top-most 64-bit PCI slots. PCI0 also has an Intel 82375EB
-PCI/EISA bridge that drives things like the serial and parallel ports,
-keyboard/mouse etc. PCI1 has 4 64-bit PCI slots and an Symbios 810 SCSI chip.
-VGA console cards must be installed in a slot connected to PCI0.
-
-Power:
-The system employs an I2C based power controller system. If you want to be
-sure all power is removed from the system pull the mains cables from the
-system. Tincup uses dual power supplies in load-sharing mode and not
-as a redundancy pair.
-
-The kernel config file must contain:
- options DEC_KN300
- cpu EV5
-
-*
-* AlphaServer 8200 and 8400 ("TurboLaser")
-*
-The AlphaServer 8200 and 8400 machines are aimed as enterprise servers.
-Expect a tall 19" cabinet (8200) or fat (8400) 19" rack. This is big iron,
-not a hobbyist system. These are multi-CPU machines, up to 12 CPUs can be in
-a single machine. The TurboLaser System Bus (TLSB) allows 9 nodes on the
-AS8400 and 5 nodes on the AS8200. TLSB is 256 bit data, 40 bit address
-allowing 2.1 Gbytes/sec. Nodes on the TLSB can be CPUs, memory or I/O. A
-maximum of 3 I/O ports are supported on a TLSB. Basic disk storage is housed
-in a StorageWorks shelf.
-
-Features:
-- 21164 EV5 CPUs at up to 467 MHz
- 21264 EV67 CPUs at up to 625 MHz
- one or two CPUs per CPU module
-- cache: 4Mbytes per CPU
-- memory bus: 256 bit with ECC
-- memory:
- uses big memory modules that plug into the TLSB, which in turn
- hold special SIMM modules.
- memory modules come in varying sizes, up to 2 Gbytes a piece.
- uses ECC (8 bites per 64 bits of data)
- 7 modules max for AS8400, 3 modules max for AS8200
- maximum memory is 14 Gbytes
-- expansion:
- 3 system 'I/O ports' that allow up to 12 I/O channels
- each I/O channel can connect to XMI, Futurebus+ or PCI boxes
-
-Memory:
-FreeBSD supports (and has been tested with) up to 2 Gbytes of memory on
-TurboLaser.
-
-Expansion:
-Only PCI expansion is supported on FreeBSD. XMI or Futurebus+ (which
-are AS8400 only) are both unsupported.
-
-The I/O port modules are designated KFTIA or KFTHA. The I/O port modules
-supply so called 'hoses' that connect to up to 4 (KFTHA) PCI buses or 1
-PCI bus (KFTIA). KFTIA has embedded dual 10baseT Ethernet, single FDDI,
-3 SCSI Fast Wide Differential SCSI buses and a single Fast Wide Single Ended
-SCSI bus. The FWSE SCSI is intended for the systems CDROM.
-
-KFTHA can drive via each of its 4 hoses a DWLPA or DWLPB box. The DWLPx
-house a 12 slots 32 bit PCI backplane. Physically the 12 slots are 3 4-slot
-buses but to the software it appears as a single 12 slots PCI bus. A fully
-expanded AS8x00 can have 3 (I/O ports) times 4 (hoses) times 12 (PCI
-slots/DWLPx) = 144 PCI slots. The maximum bandwidth per KFTHA is 500
-Mbytes/second. DWLPA can also house 8 EISA cards, 2 slots are PCI-only, 2
-slots are EISA only. Of the 12 slots 2 are always occupied by an I/O and
-connector module.
-
-For best performance distribute high bandwidth (FibreChannel, Gigabit Ethernet)
-over multiple hoses and/or multiple KFTHA/KFTIA.
-
-Currently PCI expansion cards containing PCI bridges are not usable. Don't
-use them at this time.
-
-Embedded SCSI:
-The single ended SCSI bus on the KFTIA will turn up as the fourth (!)
-SCSI bus. The 3 differential SCSI buses of the KFTIA precede it.
-
-Console:
-AS8x00 are generally run with serial consoles. Some newer machines might
-have a graphical console of some sorts but FreeBSD has only been tested on
-a serial console.
-
-For serial console usage either change /etc/ttys to have:
-
- console "/usr/libexec/getty std.9600" unknown on secure
-
-as the console entry, or add
-
- zs0 "/usr/libexec/getty std.9600" unknown on secure
-
-and make the zs node:
-
- mknod /dev/zs0 c 135 0
-
-For the AlphaServer 8x00 machines the kernel config file must
-contain:
- options DEC_KN8AE # Alpha 8200/8400 (Turbolaser)

-
-The UP1000 is an ATX mainboard based on the 21264a CPU which itself lives in
-a Slot B module. It is normally housed in a ATX [mini]tower enclosure.
-
-Features:
-- 21264a Alpha CPU at 600 or 700 MHz in a Slot B module (includes cooling fans)
-- memory bus: 128 bits to the L2 cache, 64 bits from Slot B to the AMD-751
-- on-board Bcache / L2 cache: 2Mb (600Mhz) or 4Mb (700Mhz) cache
-- AMD AMD-751 ('Irongate') system controller chip
-- Acer Labs M1543C PCI-ISA bridge controller / super-IO chip
-- PS/2 mouse & keyboard port
-- memory: 168-pin PC100 unbuffered SDRAM DIMMS
- 3 DIMM slots
- DIMM sizes supported are 64, 128 or 256 Mb in size
-- 2x 16550A serial port
-- 1x ECP/EPP parallel port
-- floppy interface
-- 2x embedded Ultra DMA33 IDE interface
-- 2x USB port
-- expansion: 4 32 bit PCI slots
- 2 ISA slots
- 1 AGP slot
-
-Slot B:
-Slot B is a box-like enclosure that houses a daughter-board for the CPU and
-cache. It has 2 small fans for cooling. Loud ones too..
-
-Memory:
-The machine needs ECC capable DIMMs, so 72 bit ones. This does not appear to
-be documented in the UP1000 docs. The system accesses the serial EEPROM on
-the DIMMs via the SM bus. Note that if only a single DIMM is used it must be
-installed in slot *2*. This is a bit counter-intuitive.
-
-Power
-The UP1000 needs a 400Watt ATX power supply according to the manufacturer.
-This might be a bit overly conservative/pessimistic judging from the power
-consumption of the board & cpu. But as always you will have to take your
-expansion cards and peripherals into account. The M1543C chip contains power
-management functionality & temperature monitoring (via I2C / SM bus).
-
-Console
-Chances are that your UP1000 comes by default with AlphaBios only. The SRM
-console firmware is available from the Alpha Processor Inc. website. It is
-currently available in a beta version which was successfully used during the
-port of FreeBSD to the UP1000.
-
-EIDE:
-The embedded Ultra DMA EIDE ports are bootable by the SRM console.
-
-SCSI:
-UP1000 SRM can boot off an Adaptec 294x adapter. Under high I/O load conditions
-machine lockups have been observed using the Adaptec 294x. A Symbios 875
-based card works just fine, using either the ncr or sym driver. The sym driver
-is the newest and most actively maintained one. Most likely other cards
-based on the Symbios chips that the sym driver supports will work as well.
-
-USB:
-Is disabled by the SRM console and has not (yet) been tested with FreeBSD.

-- 2x USB port
-- expansion: 3 32 bit PCI slots
- 1 AGP2x slot
-
-Console:
-SRM console code comes standard with the UP1100. The SRM lives in 2Mbytes of
-flash ROM.
-
-Memory:
-The machine needs ECC capable DIMMs, so 72 bit ones. This does not appear to
-be documented in the UP1100 docs. The system accesses the serial EEPROM on
-the DIMMs via the SM bus. Note that if only a single DIMM is used it must be
-installed in slot *2*. This is a bit counter-intuitive.
-
-Power
-The UP1100 needs a 400Watt ATX power supply according to the manufacturer.
-This might be a bit overly conservative/pessimistic judging from the power
-consumption of the board & cpu. But as always you will have to take your
-expansion cards and peripherals into account. The M1535D chip contains power
-management functionality & temperature monitoring (via I2C / SM bus using
-a LM75 thermal sensor).
-
-Network:
-The UP1100 has an on-board 21143 10/100Mbit Ethernet interface.
-
-Sound:
-The UP1100 is equipped with a SoundBlaster compatible audio interface.
-Whether this works with FreeBSD is as of yet unknown.
-
-EIDE:
-The embedded Ultra DMA EIDE ports are bootable by the SRM console.
-
-USB:
-The UP1100 has 3 USB ports, 2 going external and one connected to the
-AGP port.
-
-For the UP1100 the kernel config file must contain:
- cpu EV5
- options API_UP1000 # UP1000, UP1100 (Nautilus)
-
-*
-* Alpha Processor Inc. CS20
-*
-
-The CS20 is a 19", 1U high rackmount server based on the 21264[ab] CPU. It can
-have a maximum of 2 CPUs.
-
-Features:
-- 21264a Alpha CPU at 667 MHz or 21264b 833 MHz (max. 2 CPUs)
-- memory bus: 100MHz 256-bit wide
-- 21271 Core Logic chipset ("Tsunami")
-- Acer Labs M1533 PCI-ISA bridge controller / super-IO chip
-- PS/2 mouse & keyboard port
-- memory: 168-pin PC100 PLL buffered/registered SDRAM DIMMS
- 8 DIMM slots
- uses ECC memory
- min 256 Mbytes / max 2 Gbytes of memory
-- 2x 16550A serial port
-- 1x ECP/EPP parallel port
-- ALI M1543C Ultra DMA66 IDE interface
-- embedded dual Intel 82559 10/100Mbit Ethernet
-- embedded Symbios 53C1000 Ultra160 SCSI controller
-- expansion: 2 64 bit PCI slots (2/3 length)
-
-Console:
-SRM console code comes standard with the CS20. The SRM lives in 2Mbytes of
-flash ROM.
-
-Memory:
-The CS20 needs ECC capable DIMMs. Note that it uses *buffered* DIMMs.
-
-Monitoring:
-The CS20 has an I2C based internal monitoring system for things like
-temperature, fans, voltages etc. The I2C also supports 'wake on LAN'.
-
-Expansion:
-Each PCI slot is connected to it's own independent PCI bus on the Tsunami.
-
-EIDE:
-The embedded Ultra DMA EIDE ports are bootable by the SRM console.
-
-Disks:
-The CS20 has an embedded slim-line IDE CD drive. There is a front-accessible
-bay for a 1" high 3.5" SCSI hard-disk drive with SCA connector.
-
-Note that there is no floppy disk drive (or a connector to add one).
-
-The kernel config file must contain:
- options DEC_ST6600
- cpu EV5
-
-Contrary to expectation there is no 'cpu EV6' defined for inclusion in the
-kernel config file. The 'cpu EV5' is mandatory to keep config(8) happy.

-Supported hardware overview
----------------------------
-
-Word of caution: the installed base for FreeBSD/alpha is not nearly as large
-as for FreeBSD/Intel. This means that the enormous variation of PCI/ISA
-expansion cards out there has much less chance of having been tested on
-alpha than on Intel. This is not to imply they are doomed to fail, just that
-the chance of running into something never tested before is much greater.
-GENERIC contains things that are known to work on Alpha only.
-
-- Expansion buses: PCI and ISA are fully supported. Turbo Channel is not
-in GENERIC and has limited support (see the relevant machine model info).
-The MCA bus is not supported. The EISA bus is not supported for use with
-EISA expansion cards as the EISA support code is lacking. ISA cards in EISA
-slots are reported to work. The Compaq Qvision EISA VGA card is driven in
-ISA mode and works OK as a console.
-
-- Floppy drives: 1.44 Mbyte and 1.2 Mbyte floppy drives are supported.
-2.88Mbyte drives sometimes found in Alpha machines are supported up to
-1.44Mbyte.
-
-- ATA / ATAPI (IDE): are supported via the ata driver framework. As most
-people run their Alphas with SCSI disks it is not as well tested as SCSI. Be
-aware of boot-ability restrictions for IDE disks. See the machine specific
-information.
-
-- SCSI: full support via the CAM layer for Adaptec 2940x (AIC7xxx
-chip-based), Qlogic family and Symbios. Be aware of the machine-specific
-boot-ability issues for the various adapter types.
-
-- FibreChannel: the Qlogic QL2x00 FibreChannel host adapters are fully
-supported.
-
-- Ethernet: if you want to boot your Alpha over the Ethernet you will
-obviously need an Ethernet card that the SRM console recognizes. This
-generally means you need a board with an 21x4x Ethernet chip as that is
-what Digital used. These chips are driven by the FreeBSD 'de' (older driver)
-or 'dc' (newer driver). Some new SRM versions are known to recognize the
-Intel 8255x Ethernet chips as driven by the FreeBSD 'fxp' driver. But beware:
-the 'fxp' driver is reported not to work correctly with FreeBSD/alpha (although
-it works excellently on FreeBSD/x86).
-
-- FDDI: DEC DEFPA PCI FDDI network adapters are supported on alpha.
-
-- graphics console/keyboard/mouse: in general the SRM console emulates
-a VGA-compatibility mode on PCI VGA cards. This is, however, not guaranteed
-to work by Compaq/DEC for each and every card type out there. When the SRM
-thinks the VGA is acceptable FreeBSD will be able to use it. The console driver
-works just like on a FreeBSD/intel machine. The TGA video graphics which
-is embedded on for example Multia does *not* work with FreeBSD. TGA based
-PCI cards are also *not* supported. Please note that VESA modes are not
-supported on Alpha, so that leaves you with 80x25 consoles
-
-- serial ports: the 'PC standard' serial ports found on most Alphas are
-supported. For TurboChannel machines the serial ports are also supported.
-
-- ISDN (i4b): is not supported on FreeBSD/alpha

-
-In compiling this file I used multiple information sources, but
-http://www.netbsd.org proved to be an invaluable source of information.
-If it wasn't for NetBSD/alpha there probably would not be a FreeBSD/alpha
-in the first place.
