<para>Multia has enough Flash ROM to store both SRM and ARC code

<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" hard disk
|
||||
drive. Mounting stuff may have come with your Multia. Adding a
|
||||
3.5" 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" 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 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"</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>
|
||||
|
||||
<para>The kernel configuration file for a Multia kernel must

||||

Expect a tall 19" cabinet (8200) or fat (8400) 19" 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>&os; supports (and has been tested with) up to 2 GBytes

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>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>
