</itemizedlist>
<para>Multia has enough Flash ROM to store both SRM and ARC code
at the same time and allow software selection of one of them.</para>
<para>The embeded TGA video adapter is <emphasis>not</emphasis> currently
usable as a &os; console. You will need to use a serial console.</para>
<para>Multia has only one 32 bit PCI slot for expansion, and it
is only suitable for a small form factor PCI card. By
sacrificing the PCI slot space you can mount a 3.5&quot; hard disk
drive. Mounting stuff may have come with your Multia. Adding a
3.5&quot; disk is <emphasis>not</emphasis> a recommended upgrade
due to the limited power rating of the power supply
and the extremely marginal cooling of
the system box.</para>
<para>Multia also has 2 PCMCIA expansion slots. These are
currently not supported by &os;.</para>
<para>The CPU might or might not be socketed, check this before
considering CPU upgrade hacks. The low-end Multias have a
soldered-in CPU.</para>
<para>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.</para>
<para>Although the Multia SRM supports booting from floppy this
can be problematic. Typically the errors look like:</para>
<screen>*** Soft Error - Error #10 - FDC: Data overrun or underrun</screen>
<para>This is not a &os; problem, it is a SRM problem. The best available
workaround to install &os; is to boot from a SCSI CDROM.</para>
<para>There have been reports that you sometimes need to press
<keycap>Control</keycap>-<keycap>Alt</keycap>-<keycap>Del</keycap>
to capture the SRM's attention. I have
never seen this myself, but it is worth trying when you are greeted
by a blank screen after powerup.</para>
<para>Sound works fine using &man.pcm.4; driver and a line in the
kernel configuration file as follows for the Crystal CS4231
chip:</para>
<programlisting>device pcm</programlisting>
<para>The sound device lives at port 0x530, and uses irq 9 along
with drq 3. You also need to specify flags 0x15 in the <filename>device.hints</filename> file.</para>
<para>I have not yet been successful in getting my Multia with
the AD1848 to play any sound.</para>
<para>While verifying playback I was reminded of the lack of CPU
power of the 166MHz CPU. MP3 only plays acceptable using 22kHz
down-sampling.</para>
<para>Multias are somewhat notorious for dying of heat
strokes. The very compact box does not really allow access to cooling air.
Please use the Multia on its vertical stand,
don't put it horizontally (<quote>pizza style</quote>). Replacing the
fan with something which pushes around more air is really
recommended. You can also cut one of the wires to the fan speed
sensor. Once cut, the fan runs at a (loud) full speed.
Beware of PCI cards with high power consumption.
If your system has died you might want to check the
Multia-Heat-Death pages at the
<ulink url="http://www.netbsd.org/">NetBSD Web site</ulink>
for help in reviving it.</para>
<para>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:</para>
<programlisting>device ata</programlisting>
<para>The ATA interface uses IRQ 14.</para>
<para>The IDE connector pin spacing is thought for 2.5&quot; laptop
disks. A 3.5&quot; IDE disk would not fit in the case anyway. At
least not without sacrificing your only PCI slot. The SRM
console unfortunately does not know how to boot from IDE
disks. You will need to use a SCSI disk as the boot disk.</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&quot;</emphasis>
hard drive has a finer pitch than the standard SCSI flat
cables. Otherwise it would not fit on the 2.5&quot; 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>
<para>The kernel configuration file for a Multia kernel must
contain:</para>
<programlisting>options DEC_AXPPCI_33
cpu EV4</programlisting>

<title>AlphaServer 8200 and 8400 (<quote>TurboLaser</quote>)</title>
<para>The AlphaServer 8200 and 8400 machines are enterprise servers.
Expect a tall 19&quot; cabinet (8200) or fat (8400) 19&quot; rack.
This is big iron, not a hobbyist system. TurboLasers are multi-CPU
machines, up to 12 CPUs can be in a single machine. The TurboLaser
System Bus (TLSB) allows 9 nodes on the AS8400 and 5 nodes on
the AS8200. TLSB is 256 bit data, 40 bit address allowing 2.1
GBytes/sec. Nodes on the TLSB can be CPUs, memory or I/O. A
maximum of 3 I/O ports are supported on a TLSB.</para>
<para>Basic disk storage is housed in a StorageWorks shelf.
AS8400 uses 3 phase power, AS8200 uses single phase power.</para>
<para>Features:</para>
<itemizedlist>
<listitem>
<para>21164 EV5/EV56 CPUs at up to 467 MHz or 21264 EV67 CPUs at
up to 625 MHz</para>

</listitem>
<listitem>
<para>memory bus: 256 bit with ECC</para>
</listitem>
<listitem>
<para>memory: big memory modules that plug into the TLSB,
which in turn hold special SIMM modules. Memory modules come
in varying sizes, up to 4 GBytes a piece. Uses ECC (8 bits
per 64 bits of data) 7 memory modules max for AS8400,
3 modules max for AS8200. Maximum memory is 28 GBytes.</para>
</listitem>
<listitem>
<para>expansion: 3 system <quote>I/O ports</quote> that allow up to
12 I/O channels each I/O channel can connect to
XMI, Futurebus+ or PCI boxes</para>
</listitem>
</itemizedlist>
<para>&os; supports (and has been tested with) up to 2 GBytes
of memory on TurboLaser. There is a trade-off to be made between
TLSB slots occupied by memory modules and TLSB slots occupied by
CPU modules. For example you can have 28GBytes of memory but only
2 CPUs (1 module) at the same time.</para>
<para>Only PCI expansion is supported on &os;. XMI or
Futurebus+ (which are AS8400 only) are both unsupported.</para>
<para>The I/O port modules are designated KFTIA or KFTHA. The
I/O port modules supply so called <quote>hoses</quote> 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 CDROM.</para>
<para>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. DWLPB are the
prefered I/O boxes.</para>
<para>For best performance distribute high bandwidth
(FibreChannel, Gigabit Ethernet) over multiple hoses and/or
multiple KFTHA/KFTIA.</para>
<para>Currently PCI expansion cards containing PCI bridges are
not usable with &os;. Don't use them at this time.</para>
<para>The single ended narrow SCSI bus on the KFTIA will turn up as
the <emphasis>fourth</emphasis> SCSI bus. The 3 fast-wide
differential SCSI buses of the KFTIA precede it. </para>
<para>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.</para>
<para>For serial console usage either change
<filename>/etc/ttys</filename> to have:</para>
<programlisting>console "/usr/libexec/getty std.9600" unknown on secure</programlisting>
<para>as the console entry, or add</para>
<programlisting>zs0 "/usr/libexec/getty std.9600" unknown on secure</programlisting>
<para>For the AlphaServer 8x00 machines the kernel config file
must contain:</para>
<programlisting>options DEC_KN8AE # Alpha 8200/8400 (Turbolaser)
cpu EV5</programlisting>
<para>Contrary to expectation there is no <literal>cpu
EV6</literal> defined for inclusion in the kernel config
file. The <literal>cpu EV5</literal> is mandatory to keep
&man.config.8; happy.</para>
