Alpha machines are NOT like PCs. There are - considerable differences between the various core logic 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 <filename>GENERIC</filename> kernel at - unknown hardware is almost guaranteed to fail miserably.</para> - - <para>For a machine even to be considered for &os; use please - make sure it has the SRM console firmware installed. Or at least - make sure that SRM console firmware is available for the - particular machine type. If &os; 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. All bets are off when - SRM console firmware is not available.</para> - - <para>Machines with the ARC or AlphaBIOS console firmware were - intended for WindowsNT. Some have SRM console 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 means - <emphasis>no</emphasis> - &os; (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 firmware - perspective. So, be suspicious if the price appears too good.</para> - - <para>In case you have problems making your selection of SRM - 'stick', in other words if the system falls back to AlphaBIOS - after you selected the SRM console, it is time to check if the - battery of your CMOS clock/parameter RAM is empty. If so, - a replacement battery most likely fixes the issue.</para> - - <para>Known non-SRM machines are:</para> - <itemizedlist> - <listitem> - <para>Digital XL series</para> - </listitem> - <listitem> - <para>Digital XLT series</para> - </listitem> - <listitem> - <para>Samsung PC164UX (<quote>Ruffian</quote>)</para> - </listitem> - <listitem> - <para>Samsung 164B</para> - </listitem> - </itemizedlist> - - <para>Machines that have SRM but are not supported by &os; are:</para> - <itemizedlist> - <listitem> - <para>DECpc 150 (<quote>Jensen</quote>)</para> - </listitem> - <listitem> - <para>DEC 2000/300 (<quote>Jensen</quote>)</para> - </listitem> - <listitem> - <para>DEC 2000/500 (<quote>Culzean</quote>)</para> - </listitem> - <listitem> - <para>AXPvme series (<quote>Medulla</quote>)</para> - </listitem> - </itemizedlist> - - <para>To complicate things a bit further: Digital used to have so - called <quote>white-box</quote> Alpha machines destined as NT-only - and <quote>blue-box</quote> Alpha machines destined for OpenVMS - and Digital Unix. These names are based on the color of the - cabinets, <quote>FrostWhite</quote> and <quote>TopGunBlue</quote> - respectively. Although you could put the SRM console firmware on a - whitebox, OpenVMS and Digital Unix will refuse to boot on - them. &os; in post-4.0-RELEASE will run on both the white and the - blue-box variants. Before someone asks: the white ones had a - rather different (read: cheaper) Digital price tag.</para> - - <para>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. The ARC console - firmware contains a different PAL code, geared towards WinNT and - in no way suitable for use by &os; (or more generic: Unix or - OpenVMS). Before someone asks: Linux/alpha brings its own PAL - code, allowing it to boot on ARC and 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. If you are interested - in the gory details search the &os; and NetBSD web sites.</para> - - <para>There is another pitfall ahead: you will need a disk adapter - that the SRM console firmware recognizes in order to be able to boot from - a disk. What is acceptable to SRM as a boot adapter is - unfortunately highly system and SRM version dependent. For older PCI - based machines it 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 more modern - 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 NCR sometime.</para> - - <para>The problem might bite those who have machines that started - their lives as WindowsNT boxes. The ARC or AlphaBIOS knows about - <emphasis>other</emphasis> adapter types that it can boot from - than the SRM. For example you can boot from an Adaptec 2940UW with - ARC/AlphaBios but (generally) not with SRM. Some newer machine types have - introduced Adaptec boot support. Please consult the machine - specific section for details.</para> - - <para>Most 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 - WindowsNT) systems. SRM versions exist (depends on the machine type) - that can boot from IDE disks and CDROMs. Check the machine - specific section for details.</para> - - <para>In order to be bootable the root partition (partition a) - must be at offset 0 of the disk drive. This means you have to - use the installer's partitioning menu and start with assigning - partition a at offset 0 to the root partition. Subsequently layout - the rest of the partitions to your liking. If you do not adhere - to this rule the install will proceed just fine, but the system - will not be bootable from the freshly installed disk. Note that - fdisk is not used on &os; running on Alpha, disks are directly - labeled using disklabel.</para> - - <para>If you don't have/want a local disk drive you can boot via - the Ethernet. This assumes an Ethernet adapter/chip that is - recognized by the SRM console. Generally speaking this boils down to - either a 21040 or 21142 or 21143 based Ethernet interface. Older - machines or SRM versions may not recognize the 21142 / 21143 Fast - Ethernet chips, you are then 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.</para> - - <para>Alpha machines can be run with SRM on a graphics console or - on a serial console. ARC can also be run on a serial consoles if need - be. VT100 emulation with 8 bit controls should at least allow you - to switch from ARC/AlphaBIOS to SRM mode without having to install a - graphics card first.</para> - - <para>If you want to run your Alpha machine 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 also 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. <emphasis>This can be extremely - confusing.</emphasis></para> - - <para>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.</para> - - <para>Most PCI devices from the PC-world will also work in - &os; PCI-based machines. Check the - <filename>/sys/alpha/conf/GENERIC</filename> file for the latest word - on this. 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:</para> - - <screen><prompt>>>></prompt> <userinput>SET PCI_PARITY OFF</userinput></screen> - - <para>This is not a &os; problem, all operating systems running on - Alpha hardware will need this workaround.</para> - - <para>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 after you have upgraded your - console firmware.</para> - - <para>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, EV68. 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 <quote>EV</quote> the more desirable - (read: faster / more modern). Spending money on anything less than - an EV5 is not recommended. Hardware available for free is a different - matter of course.</para> - - <para>For memory you want at least 32 Mbytes. I have had - &os; run on a 16 Mbyte system years ago but you will not enjoy - that. Kernel build times halved when I went to 32 Mbytes. Note that - the SRM console steals 2Mbyte from the total system memory (and keeps - it). For more serious work 128 Mbytes or more are recommended. - Although Alpha machines typically can accommodate large to very large - physical memory sizes, &os; is limited to 1 or 2 Gbytes (dependent - on the core chipset) of RAM. This restriction is due to the - current implementation of the VM system.</para> - - <para>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.</para> - - <para>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 if something is not clear after reading this - document.</para> - - </sect2> - - <sect2> - <title>System-specific information</title> - - <para>Below is an overview of the hardware that &os; runs on.

NoName 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.</para> - - <para>Due to the limited memory interface the system is not - particularly fast in case of cache misses.

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 only need SRM - anyway.</para> - - <para>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.</para> - - <para>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.
