[9fans] Boot problems

[andrew.simmons]

Having been inspired to work through Nemo's outstanding draft book - for
which many many thanks - I've been trying to install a recent build of Plan9
on my antique Thinkpad 380XD, which was running an older build in peaceful
coexistence with Windows 95, and I have hit a few problems.

Given that no-one was any longer using the machine to run Windows 95, I
decided to trash the Windows partition and give the whole disk over to Plan
9. The installation completed after a few problems, I selected plan9 as the
boot method and - I think this could have been my mistake - I elected to
overwrite the existing MBR. When I powered up the machine, it briefly
displayed 'MBR...', which vanished to be replaced by an underscore, after
which nothing happened.

Having looked through the archives, I tried:

disk/format -b /386/pbs /dev/sdC0/9fat

which reported 'used 0 bytes' On re-booting, the machine displayed:

MBR...PBS1...

and then nothing happened.

I tried using /386/pbslba instead, and got:

MBR...PBS2...

after which nothing happened. The machine boots fine from CD, but seems to
lose touch with the CD drive after a while and then lock up.

I have no clue what I am doing here, and would appreciate any suggestions.

I didn't explicitly do this, just let the installation run its course - 
I'll have a look to see what's actually on 9fat later on, thanks.

Probably you did, but, did you copy 9load to 9fat along with
a Plan 9ini and a kernel?

Know it sounds stupid, but time ago I forgot and just didn't
notice.

If you make yourself a boot floppy do you still have problems?

(You can do this by booting the install floppy again;
it knows you're done with the install and will let you
make a boot floppy.)

I just installed plan 9 on my machine (ABit VP6, dual pentium 3-board), and the
install went through fine. However, when I try to boot the newly-installed
system, I get the following output:

Press almost any key to reset..




I'm booting the system using grub (just chainload the p9 partition). I added
the debug=1 option to the first line of plan9.ini, but I got no additional info
(This is actually the output with debug=1).

Any help would be greatly appreciated.

BTW, please include me on replies, as I'm not subscribed to 9fans.
