We don't have kernel command line argument support in the prom yet, so
you have to compile your desires into the kernel at ... well ... compile
time. In other words, you have to set root=3D/dev/nfs and ip=3Ddhcp in =
the
config file in CONFIG_CMDLINE.  Remove root=3D/dev/sda1 of course.  If
you want NFS Root.

Cheers,
