Subject: [9fans] plan 9 on an IBM eserver 325

Hello 9fans,

I've recently acquired such a machine (bi proc opteron) and I thought
it'd be nice if I can make a cpu server out of it and hook it up on the
net at work so that it can be made available for the 9fans out there.

I've tried booting on an iso I fetched yesterday, but 9load was not so
happy about it; here's what it printed at boot (possibility of typoes
not totally excluded):

ELCR: 0C80
apm ax=f000 cx=f000 dx=40 di=ffff ebx=5d84 esi=-1
initial probe, to find plan9.ini... dev A0 port 1F0 config 0040 capabilities 2F00 mwdma 0007 udma 407F
dev A0 port 170 config 85C0 capabilities 2F00 mwdma 0007 udma 0407
FLAGS=10282 TRAP=6 ECODE=0 PC=3
 AX 00000000 BX 80815d78 CX 00000000 DX 800fdfc0
 SI 00001022 DI 00000024 BP 0000746b
 CS 0010 DS 0008 ES 0008 FS 0008 GS 0008
 CR0 80000011 CR2 0000000 CR3 0000c000
panic: exception/interrupt 6

Erik said I should try with a 9load from may 2007 or earlier, so I was
wondering if anyone of you had one handy, or if there's a way to obtain
one easily (mounting an old snapshot?)? Or any other suggestion to have
the iso booting a bit further?

Also do you think there's any chance I can have plan9 working on
this machine or are there any other incompatibilities I have not yet
discovered? (I know about the unsupported broadcom NICs, but that should
be fixable by plugging another NIC). Am I simply better off installing
Linux with inferno on top of it?

Any other suggestion?

Here's more information about the machine (and the output of lspci -vn
is attached):

Thanks,
Mathieu.
