<title>In general, what do you need to run &os; on an Alpha?</title>
|
|
|
|
<para>Obviously you will need an Alpha machine that &os;
|
|
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 <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 this
|
|
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.</para>
|
|
|
|
<para>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 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
|
|
perspective. So, be suspicious if the price appears too good.</para>
|
|
|

|
|
<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 on the
|
|
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) 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 by the way. The ARC
|
|
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.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>The problem might bite those who have machines that started
|
|
their lives as WinNT 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>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.</para>
|
|
|
|
<para>&os; 4.0 and later can be booted from the
|
|
distribution CDROM. Earlier versions needed booting from a
|
|
2-floppy set.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>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/AlphaBIOS to SRM mode without having to install a
|
|
graphics card first.</para>
|
|
|
|
<para>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.</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.
|
|
Please note that TGA cards are not currently supported as &os; console
|
|
display cards.</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. 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: <userinput>SET PCI_PARITY OFF</userinput>.
|
|
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 have upgraded your console firmware.</para>
|
|
|
|
<para>Parallel ports that can be found on most Alpha machines are
|
|
supported.</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. 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).</para>
|
|
|
|
<para>For memory you want at least 32 Mbytes. I have had
|
|
&os; 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 64 Mbytes or more are recommended.</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.</para>

<para>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.</para>
|
|
|
|
<para>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. It is a full-fledged 64 bit CPU, just don't expect

|
miracles as far as speed goes.</para>

<para>NoNames can either have SRM <emphasis>or</emphasis> ARC console

selection of alternate console code. But you need SRM-only
|
|
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

<para>It comes with a TGA based graphics on-board. TGA is not

currently suitable for console use with &os;. This means you will have

to run Multia 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

<para>Multia has 2 serial ports but routes both of them to the

used.</para>

<para>Although the Multia SRM supports booting from floppy this

can be problematic. Typically the errors look like:

<screen>
|
|
*** Soft Error - Error #10 - FDC: Data overrun or underrun
|

|
|

This is not a &os; problem, it is a SRM problem. The best available

<para>Multias are somewhat notorious for dying of heat

don't put it horizontally (<quote>pizza style</quote>). 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

<para>The Intel 82378ZB PCI to ISA bridge enables the use of an

|
|

|
<para>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.</para>
|
|
|
|
<para>The SRM console does not know how to boot from IDE

disks unfortunately.</para>
|

|
|
<para>In case you want to change the internal hard drive: the
|
|
internal flat cable running from the PCI riser board to the
|
|
<emphasis>2.5"</emphasis>
|
|
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.</para>
|
|
|
|
<para>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 50-pin SCSI

connector but some Multia models came without disk and may lack
|
|
the connector. Something to check before buying one.</para>

<title>Personal Workstation (<quote>Miata</quote>)</title>
|
|
|
|
<para>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 done, yielding the
|
|
MiataGL. Unfortunately the variants are not easily distinguishable
|
|
from the outside of the case.
|
|
An easy check is to see if the back of the machine sports two
|
|
USB connectors. If yes, it is a MiataGL.</para>
|
|
|
|
<para>System designations look like <quote>Personal Workstation
|
|
433a</quote>. 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
|
|
<quote>a</quote>). Systems designated from day 1 to run Tru64
|
|
Unix or OpenVMS will sport <quote>433au</quote>. 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].
|
|
|
|
<para>There was also a Miata model with a special CPU cooling
|
|
system by Kryotech. The Kryotech has a special cooling system

and is housed in a different enclosure.</para>

<para>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.) is
|
|
identical for MX5 and MiataGL.</para>
|
|
|
|
<para>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 <quote>known good</quote> to the SRM are allowed to
|
|
be used in the 64bit slots.</para>
|
|
|
|
<para>If you want to fool the SRM you can type <userinput>set
|
|
pci_device_override</userinput> at the SRM prompt. Just don't
|
|
complain if your data mysteriously gets mangled.</para>
|
|
|
|
<para>The complete command is:
|
|
|
|
<screen><prompt>>>></prompt> <userinput>SET PCI_DEVICE_OVERRIDE <replaceable><vendor_id></replaceable><replaceable><device_id></replaceable></userinput></screen></para>
|
|
|
|
<para>For example:
|
|
|
|
<screen><prompt>>>></prompt> <userinput>SET PCI_DEVICE_OVERRIDE 88c15333</userinput></screen></para>
|
|
|
|
<para>The most radical approach is to use:
|
|
|
|
<screen><prompt>>>></prompt> <userinput>SET PCI_DEVICE_OVERRIDE -1</userinput></screen></para>
|
|
|
|
<para>This disables PCI ID checking altogether, so that you
|
|
can install any PCI card without its ID getting
|
|
checked. For this to work you need a reasonable current SRM version.

|

|
|
<para>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.</para>
|
|
|
|
<para>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
|
|
&os; kernel by the way.</para>
|
|
|
|
<para>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 &os; from an IDE disk. Speeds on MX5 are around 14
|
|
Mbytes/sec assuming a suitable drive. Miata's CMD646 chip will
|
|
support up to WDMA2 mode as the chip is too buggy for use
|
|
with UDMA.</para>
|
|
|
|
<para>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 <emphasis>same</emphasis> chip as the
|
|
MiataGL. All in all there is a lot of variation.</para>
|
|
|
|
<para>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 <quote>before</quote> the bridge, in
|
|
one of the 64 bit PCI slots.</para>
|
|
|
|
<para>Both MX5 and MiataGL have an on-board sound chip, an
|
|
ESS1888. It emulates a SoundBlaster and can be enabled by

putting

|
|
|
|
<para>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.</para>
|
|
|
|
<para>Installing a 2Mb cache module achieves, apart from a
|
|
10-15% speed increase (based on buildworld elapsed time), a
|
|
<emphasis>decrease</emphasis> 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

<para>Currently DEC3000 machines can only be used diskless on
|
|
&os;. The reason for this is that the SCSI drivers needed
|
|
for the TC SCSI adapters were not brought into CAM that the
|
|
recent &os; versions use. TC option cards for single (PMAZ-A) or
|
|
dual fast SCSI (PMAZC-AA) are also available. These cards currently
|
|
have no drivers on &os; either.<para>

<para>DEC3000/300 has 5 MBytes/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.<para>
|
|
|
|
<para>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, for example:
|
|
<screen><prompt>>>></prompt> <userinput>BOOT DKA300</userinput></screen>

<para>The 3000/300 series has a half-speed TurboChannel compared

<para>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
|
|
<quote>seen</quote> as a 8 Mbyte SIMM. 8 Mbyte and 32 Mbyte
|
|
SIMMs can be mixed, as long as the pairs themselves are
|
|
identical.</para>
|
|
|
|
<para>When you find yourself in need of fixing 32Mbyte SIMMs
|
|
that lack correct presence bits the following info might be of
|
|
use:</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>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).</para>
|
|
|
|
<para>If you bridge a pair of pads with a small resistor or a
|
|
drop of solder you ground that particular bit.

<para>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

<para>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.</para>

<para>The SRM console code is housed in an UV-erasable EPROM. No

|
|
|
|
<para>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 &os; 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 &os; 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.</para>

<para>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.</para>
|

|
|
<para>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.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>164LX and 164SX with SRM firmware version 5.8 or later can boot
|
|
from Adaptec 2940-series adapters.</para>
|
|
|
|
<para>In summary: this family of machines is 'blessed' with a
|
|
challenging compatibility as far as SCSI adapters go.</para>
|
|
|
|
<para>On 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. </para>
|
|
|
|
<para>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 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.</para>
|
|
|
|
<para>PC164 can boot from IDE disks assuming your SRM version is
|
|
recent enough.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>For the EB164 class machines the kernel config file must
|
|
contain:

|
<programlisting>options DEC_EB164

<para>The AlphaServer 1000 and 800 range of machines are intended as

departmental servers. They come in quite some variations in packaging

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.</para>

<para>AlphaServer 800 has a much smaller mini tower case, it lacks the

PCI slots and has EISA slots instead.</para>

<para>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.</para>
|
|

|
(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..)</para>

consoles. They need <prompt>>>></prompt> <userinput>
|
|
SET CONSOLE SERIAL</userinput> before they go for a serial console.
|

Pulling the keyboard from the machine is not sufficient, like it is
|
|
on many other Alpha models. Going back to a graphical console needs
|
|
<prompt>>>></prompt> <userinput>SET CONSOLE GRAPHICS
|
|
</userinput> at the serial console. On Lynx keep the VGA card in

|
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 &os; 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.

<title>AlphaServer 4100 (<quote>Rawhide</quote>)</title>
|
|
|

<programlisting>
|
|
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.

|
|
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.

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:
|
|
&os; supports (and has been tested with) up to 2 Gbytes of memory on
|
|
TurboLaser.
|
|
|
|
Expansion:
|
|
Only PCI expansion is supported on &os;. 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 &os; 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
|

<title>Alpha Processor Inc. UP1000</title>
|
|
|
|
<programlisting>
|
|
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 &os; 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 &os;.
|
|
|
|
For the UP1000 the kernel config file must contain:
|
|
cpu EV5
|
|
options API_UP1000 # UP1000, UP1100 (Nautilus)

<title>Supported Hardware Overview</title>
|
|
|
|
<para>A word of caution: the installed base for &os; is not
|
|
nearly as large as for &os;/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.
|
|
<filename>GENERIC</filename>
|
|
contains things that are known to work on Alpha only.</para>
|
|
|
|
<para>The PCI and ISA expansion busses are fully supported. Turbo
|
|
Channel is not in <filename>GENERIC</filename> 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.</para>
|
|
|
|
<para>1.44 Mbyte and 1.2 Mbyte floppy drives are supported.
|
|
2.88 Mbyte drives sometimes found in Alpha machines are supported up to
|
|
1.44Mbyte.</para>
|
|
|
|
<para>ATA and ATAPI (IDE) devices are supported via the &man.ata.4;
|
|
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.</para>
|
|
|
|
<para>There is full SCSI 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.</para>
|
|
|
|
<para>The Qlogic QL2x00 FibreChannel host adapters are fully
|
|
supported.</para>
|
|
|
|
<para>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 &os; &man.de.4; (older driver) or &man.dc.4; (newer
|
|
driver). Some new SRM versions are known to recognize the Intel
|
|
8255x Ethernet chips as driven by the &os; &man.fxp.4; driver. But
|
|
beware: the &man.fxp.4; driver is reported not to work correctly
|
|
with &os; (although it works excellently on &os;/x86).</para>
|
|
|
|
<para>DEC DEFPA PCI FDDI network adapters are supported on alpha.</para>
|
|
|
|
<para>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 &os; will be able to use it. The
|
|
console driver works just like on a &os;/intel machine. The TGA
|
|
video graphics which is embedded on for example Multia does
|
|
<emphasis>not</emphasis>
|
|
work with &os;. TGA based PCI cards are also <emphasis>not</emphasis>
|
|
supported. Please note that VESA modes are not supported on Alpha,
|
|
so that leaves you with 80x25 consoles.</para>
|
|
|
|
<para>The <quote>PC standard</quote> serial ports found on most
|
|
Alphas are supported. For TurboChannel machines the serial ports
|
|
are also supported.</para>
|
|
