[9fans] Plan 9 doesn't boot on a (fairly new) computer

[Jorden Mauro]

Here's the hardware:

AMD Athlon II X2 245 (64-bit dual core)
Gigabyte GA-MA785GM-US2H motherboard
One 1.5Tb SATA hard drive, old IDE cdrom

The Plan 9 and 9atom liveCDs have the same problem: when the `root is
from' prompt appears,
nothing happens and the keyboard does not work. The keyboard is not
usb and no usb devices
are plugged in. Both liveCDs apparently have nomp set, as only one cpu
is detected.

I had to change the `boot from' option on the vanilla Plan 9 CD,
because my motherboard/BIOS
does not let me have IDE drives as secondary master. 9atom seemed to
handle this better, but
both get stuck at the `root is from' prompt. Someone suggested Plan9
may not like the southbridge
on this motherboard (an AMD SB710).

Any ideas?

Thanks,
Jorden

is there a legacy usb option in bios? if there is, i would
turn that off. also, could you send me the output of
pci or lspci offline. i'd like to double check the southbridge
and the ahci/ide dids. i suspect that's the problem.

Is there any 64-bit supported Plan 9 kernel?

from what I understand no (and I am sure others will correct me if I am
wrong). What I can say definitively is that Plan 9 will run on a 64-bit
machine when compiled in 32-bit mode. My primary machine has a AMD Phenom
II X4. It is one of those cheap Gateway machines, which unfortunately do
not give you lots of details of what is under the hood (and I might not
have bought it for that if I had fully know up front). So the good news is
that you can probably get it to work. The best place to start looking it
look at Erik's 9atom boot disk and you might have to play around with the
SATA/IDE settings (which on my bios caused lots of problems). The should
be a hundred or so posts in the archives dealing with 64-bit machines and
booting with 9atom.

Hope that helps.

Thanks.

I was just curious; I heard there was some 64-bit support in the works.

Best,
