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.
