[9fans] Eeepc

[9fans] Eeepc

[Jon Dugan]

Hello,

I recently bought an Eeepc and although I have Plan 9 running inside
Parallels on my Mac I thought it would be interesting to see if I could
get it installed on the Eeepc.

I booted from an ISO image I downloaded on March 19th.  Unfortunately I
didn't get too far.  Here's the console output:

PBS1...Plan 9 from Bell Labs
ELCR: 0CA8
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: South bridge 8086, 2641 not found

And then we're back to the boot prompt.

Is there any hope?  I don't have much experience in the Plan 9 code
base, but I'm not afraid to get my hands dirty.  I've looked around in
the code a bit but nothing stood out to me.  Any suggestions about what
I might try next would be most appreciated.

Thanks!

Jon

 A couple of people on irc (freenode, #plan9) were interested in plan
9 on the eee - dho and stefanha. Don't know if they've made much/any
progress yet, but you're not alone.

Re: [9fans] Eeepc

[Stefan Hajnoczi]

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

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.

Re: [9fans] Eeepc

I don't think 9load can just boot off a usb yet.

Can the eee bios make the usb look like a disk? What were those
options in plan9.ini for letting the bios do the disk access?

I am just playing with that right now.  I have removed *nobiosload
from plan9.ini.  But I think 9load isn't able to access my plan9.ini
on the USB stick.

*nobiosload may need to be disabled?

Re: [9fans] Eeepc

Here is the output after commenting out "|| !biosinited" in
/sys/src/boot/pc/devbios.c:137:
bios0: drive 0x80: 4001292288 bytes, type 3
biosinit: sorry, only one bios drive; can't read last one

(From reading the 9load code I don't understand how biosinited is ever
1 when biosinit() gets called.  The only place that sets biosinited is
in biosinit(), but to get there biosinited must already be set to 1!)

The drive detected seems to be the 4 GB SSD.

Either the BIOS is not exposing the USB stick as a disk, or the 9load
BIOS device code isn't searching correctly.  I'm going to give it a
rest here for now.

This is easy to see. Install a pbs on it and see if it gets loaded and run.
If it is not, the BIOS does not see it. Take a look at the configuration of the
BIOS and try to set USB as (better if it is the first) a boot device.

I have been running PBS off the USB stick the whole time.  It's the
step from 9load to the kernel which isn't working.  9load isn't able
to find plan9.ini or the kernel I tell it on the USB stick - it
doesn't even seem to be able to see the USB stick at all.

But your point stands: PBS is using the USB stick via the BIOS.  There is hope.
