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 - http://www.netbsd.org/Ports/alpha/multiafaq.html - http://www.brouhaha.com/~eric/computers/udb.html - -* -* 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: - - DEC3000/400 Sandpiper 133MHz CPU, desktop - DEC3000/500 Flamingo 150MHz CPU, floor standing - DEC3000/500X Hot Pink 200MHz CPU, floor standing - DEC3000/600 Sandpiper+ 175MHz CPU, desktop - DEC3000/700, Sandpiper45 225MHz CPU, floor standing - DEC3000/800, Flamingo Ultra 200MHz CPU, floor standing - DEC3000/900, Flamingo45 275MHz CPU, floor standing - - DEC3000/300 Pelican 150MHz CPU, desktop, 2 TC slots - DEC3000/300X Pelican+ 175MHz CPU, desktop, 2 TC slots - DEC3000/300LX Pelican+ 125MHz CPU, desktop, 2 TC slots - DEC3000/300L 100MHz CPU, desktop, no TC slots - - -Features: -- 21064 CPU (100 to 200 MHz) - 21064A CPU (225 to 275 MHz) -- memory bus: 256 bit, with ECC [DEC3000/500-class] - 64 bit, with ECC [DEC3000/300-class] -- memory: - proprietary 100pin SIMMs - installed in sets of 8 [DEC3000/500-class] - - PS/2 style 72pin 36 bit FPM SIMMs, 70ns or better - used in pairs of 2 [DEC3000/300-class] -- Bcache / L2 cache: varying sizes, 512 kB to 2 Mbyte -- built-in 10Mbit Ethernet based on a Lance 7990 chip, AUI and UTP -- one or two SCSI buses based on a NCR53C94 or a NCR53CF94-2 chip -- 2 serial ports based on Zilog 8530 (one usable as a serial console) -- embedded ISDN interface -- on-board 8 bit sound -- 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).

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.

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.

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).

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.

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.

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 - -Acknowledgments ----------------- - -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. - -People who kindly helped me create this document: - -- Nick Maniscalco <nmanisca@vt.edu> -- Andrew Gallatin <gallatin@cs.duke.edu> -- Christian Weisgerber <naddy@mips.rhein-neckar.de> -- David O'Brien <obrien@NUXI.com> -- Wim Lemmers, ex-Compaq -- Matthew Jacob <mjacob@feral.com> -- Eric Schnoebelen <eric@cirr.com> -- Chuck Robey <chuckr@picnic.mat.net> -- Mike Smith <msmith@FreeBSD.ORG> -- Peter Jeremy <peter.jeremy@alcatel.com.au> -- Dolf de Waal <l.j.de.waal@kader.hobby.nl> -- Wouter Brackman, Compaq -- Kazutaka YOKOTA <yokota@zodiac.mech.utsunomiya-u.ac.jp> -- Peter van Dijk <petervd@vuurwerk.nl> -- Lodewijk van den Berg, Compaq |
