Thanks. That fixed the problem. For the faint at heart, here is what I did:

cd /sys/src/9/pc

acme main.c

At the bottom of the file there is a function named idlehands(void). Change that function to do nothing but call halt().

Then, from that same directory, build the kernel with:

mk 'CONF=pcf'

Then install the kernel with:

9fs 9fat

cp 9pcf /n/9fat

Halt the system with:

fshalt

Reboot the machine.

change idlehands in /sys/src/9/pc to call halt unconditionally instead of
whatever it's doing now.
