Re: [9fans] Eeepc

["Stefan Hajnoczi" <stefanha@gmail.com>]

I just played with an Eee PC for a few minutes.  So the Eee PC's
southbridge is not supported by 9load or the kernel.  See
/sys/src/boot/pc/pci.c and /sys/src/9/pc/pci.c for the southbridges
list.

I'm not sure how to boot Plan 9 without a CD-ROM drive, so I used dd
to copy the ISO's bootdisk.img onto a USB stick.

I was able to reproduce your error.  Then I opened 9load in a hex
editor and changed the 0x8086 0x2640 southbridge entry to 0x8086
0x2641.  Here's the result:
PBS1...Plan 9 from Bell Labs
ELCR: 0C28
apm ax=f000 cx=f000 dx=40 di=100 ebx=ef50 esi=ffff
initial probe, to find plan9.ini...dev A0 port 170 config 044A
capabilities 0300 mwdma 0007 udma 101F
pcirouting: 8086/2653 at pin 2 irq 5
pcirouting: 8086/266A at pin 2 irq 5

Boot devices: fd0 sdD0!dos
boot from:

(Note I tried recompiling 9load properly instead of hex editing, but
got hangs and resets)

I have disabled all devices except USB in the BIOS and set "OS
Installation" to "Start".

I am stuck at this point because I have not been able to tell 9load to
boot 9pccd.gz.
