[9fans] Install problems

[Mike Fletcher <mlf@eecs.tulane.edu>]

I am having trouble trying to install Plan9 rel.3 on my laptop.
It's a TI Extensa 565, 75MHz Pentium with 40M ram and a free
500MB area on the disk (the first 250MB belongs to MS-DOS.)

My install disk is from the 12 Apr 01 disk image.  Here's what
happens:

Insert disk and power on.
PBS works ok
apm  is found -- is this the power management Bios ?
loader find fd0!dos!plan9.ini
dev A0 1F0  is found -- must be the IDE disk ctlr
9PCFLOP.GZ is found and unzipped (many dots followed by sizes
    looks like the old text+data+bss stuff)
loader finds cpu0, #y0 (an i82365SL), and dev A0 again and says:
5830 free pages
23320K bytes
114520K swap
root is from     offers local!/bzroot as the default - I take it.
next comes     kfs...boot: nop...      and then
                                                Different errors
bunzip2: decompress failed                      sometimes
kfs: premature eof reading /386/bin/ip/ppp      <----
boot fatal: read nop: file does not exist
panic: boot process died: unknown               but always this
ktrace /kernel/path 801064e2 80007ce4           <---- address
 [a hex dump follows this -- and finally...]
cpu0: exiting

And the machine freezes.

I have rebuilt the diskette several times and tried it in other 
systems and get either some version of a rio screen, or at least 
an rc % prompt.

Possible problem may be that my Bios shadows the system ROM to
F605-FFFF, and there is no way to disable shadowing in the Bios
setup.  Am I just outta luck?
                                                       
I have a working Plan9 system on a desktop machine (built from
an earlier version of 9disk.9fd) if that could help me debug
things; but the laptop has no network card.

I'd appreciate any ideas you may have on how to get the install
working.

Thanks,
