[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.

did you try with *nobiosload?  i put an old 9load in /n/sources/contrib/quanstro/old9load

In addition to the one erik's now posted for you, you can get at the
archived snapshots on sources from any net-connected plan9 machine
(say a virtual machine or account on somebody else's cpu server):

Nope, I haven't tried yet because that requires that I make myself a
new iso, and I'm uncertain as how to proceed for that.  Shall I mount
the current iso, copy everything on some temporary location, locate
where plan9.ini is, modify it, and just create an iso9660 fs from that
temporary tree?

Thx for the old 9load.

assuming you already have a fileserver, you may just want a boot floppy.
lacking a physical floppy, you can build an eltorito from the floppy image.

this isn't something i've done in a very long time as i find it much easier to
find a workable nic and pxe boot.

2 years ago, someone had a similar problem, so I modified
9load so people could set and edit the variables at boot time,
the code is on sources /n/sources/contrib/fgb/tar/9load.tgz

here's a post explaining how it worked.

[Mathieu Lonjaret]

So, back to this issue.
I've finally figured out how to make a bootable iso ( for future
search in the archives: /n/sources/contrib/maht/rc/mkiso ,
/sys/lib/dist/pc/mkfile , and
http://maht0x0r.blogspot.com/2007/11/roll-your-own-plan9-iso.html were
pretty much the only useful docs I could find on that matter).
First I made a "regular" one, which of course didn't change a thing
for this ibm machine.
Then I made one with *nobiosload=1 in the [common] section of its
plan9.ini and with the old 9load you put in your contrib, but it still
panics in the same way I described in the previous post. I'm pasting
it again, as a reminder:

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

 CR0 80000011 CR2 0000000 CR3 0000c000
panic: exception/interrupt 6

Any other suggestion please?

In the meanwhile I'm gonna try fgb's 9load and see what can be done with that.

Cheers,
Mathieu.

you're still using a newish 9load.  the tipoff is the line
that says
	initial probe, to find plan9.ini... dev A0 port 1F0 config 0040

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

[lejatorn]

Heh, you got me there. It's just that I was too lazy to rewrite all the
stuff by hand. I only compared what was on the screen to that previous
message and when I saw the value were the same I pasted again the old
message. But I had indeed noticed that line was absent.
So yeah, with the old 9load that line is not there and it still panics.

have you verified that the PC=3 with the older 9load?  with an
actual program counter, finding the problem would be easier.
