[9fans] Plan 9 on Fit-PC

[9fans] Plan 9 on Fit-PC

[sqweek]

 I ordered a fit-pc recently to replace my old noisy server, and
figured I should do the right thing and give plan9 a chance before
installing netbsd or somethnig.
 It has proven a bit awkward to bootstrap with no IDE/floppy slots to
plug in to, but eventually I worked out if you plug a usb cd drive in
and tell the BIOS there's an IDE Primary slave and to boot from
"CDROM" it actually boots from the usb...
 So I stuck the PLAN 9 - FEB 8 2008 04:01 iso in, and it gets this far:

PBS1...Plan 9 from Bell Labs
ELCR: 0E20

 And freezes.

 I also tried to netboot from my existing cpu/auth/file server. The
netboot ROM on the ethernet downloads the kernel but couldn't seem to
find a spot in memory to put it[1], so I grabbed gPXE 0.9.3 from
http://www.etherboot.org/ and built an ISO. The last thing I see there
is "Booting from /386/9pc..." and then the machine reboots. I'm not
sure if this is even getting the whole kernel... last line in
/sys/log/ipboot is:

phoenix Feb 26 00:24:43 send file '/386/9pc' octet to 192.168.1.11!1024

 THNX might be another option for bootstrap, or at least useful for
getting the plan 9 bootloader on the MBR - I have it on a usb stick
and got it running with a bit of messing around.
 Finally, the thing has a serial port, but I don't know how to use those things.

 Does it sound like this hardware is likely to run plan 9?

that went by a bit fast for me.

do you mean that you are pxe loading 9pxeload but the bios pxeloader
can't find a place for 9pxeload in memory?  or that 9pxeload loaded but
couldn't load the kernel?  the plan 9 kernel can't be pxe loaded directly.
it's too big & l.s doesn't handle real mode.

can you boot a standalone linux and
cat /proc/cpuinfo
and
lspci
and
lspci -v

 Ahh, that's what I'm doing wrong. Doesn't surprise me, I'm new to netbooting ;)
 Also, /lib/ndb/local.complicated has bootf arguments that refer to
real kernels so it didn't occur to me to look for something else. With
bootf=/386/9pxeload, the netboot gets as far as the cd boot - ie it
freezes after "ELCR: 0E20".
 Thanks.
