[9fans] T21 boot failure after successful install

[9fans] T21 boot failure after successful install

[Anthony Sorace]

i've recently acquired an IBM ThinkPad T21, which claims to be
supported, so of course i did the only sensible thing to do with such
kit: i installed plan 9 on it. the install went (seemingly)
flawlessly, but upon rebooting, things hang very early on, right after
this:

MBR...PBS...Plan 9 from Bell Labs
ELCR: 0800
apm ax=f000 cx=f000 dx=40 di=ffff ebx=43b3 esi=-1
dev A0 port 1F0 config 045A capabilities 0F00 mwdma 0007 udma 041F
dev A0 port 170 config 85C0 capabilities 0F00 mwdma 0007 udma 0407

the lines are reliably the same.

also, the freshly-installed 9fat partition has no plan9.ini in it.
that seems odd. i've tried creating one (based of the one in
/sys/lib/dist/pc/plan9.ini.cd, since the cd boot works just fine), but
that had no discernible effect. my thought was that something from the
plan9.ini would be making a difference (*nomp, maybe?), but that at
least seems not to be it.

all help greatly appreciated.

don't the ethernet drivers get initialized before the ata disks,
which do print a message?

Try booting a cd and then running

9fat:
cp /386/9loadlite /n/9fat/9load
chmod +al /n/9fat/9load

and then try booting again.  Perhaps one of the ethernet
drivers is timing out.  That's the only difference
in 9load that I can think of between the CD
and the installed system.

in 9load, no.
in the kernel, yes.

well, that's changed the behavior, at least. now i get to 'boot from',
but fd0 is the only recognized boot device (which is odd, since
there's no floppy in the thing).

the kernel from the cd does report an elnk3; i've not yet had a chance
to test the network on it. again, though, the cd kernel boots clean
with no problem.

Anybody tried it on a T43?

I had a T21 with the 3com.  Up until the 9load changes last year it was
successfully booting, but I ran into an unresolved hang after that
(approx. early November).  I could boot from floppy and then run the KFS
system, but my previous boot from the WinXP boot menu now failed.

Never got it resolved since shortly afterwards I had to hand the T21
back to my employer in a blank and formatted state.

If I remember correctly, the T21 can have either an Intel 82557 or
a 3Com mini-PCI ethernet installed. If it's the latter, I don't
think we've ever tried that and possible problems with the 3Com
drivers have been reported recently.
