The answer, as all the respondents pointed out was that somehome (I don't know
how) the file /boot was missing. An installboot fixed it.
The process I used:
Booted it as a diskless client.
# mount /dev/sd0a /mnt
# cd /mnt
# ftp'd /boot from another IPX to /mnt/boot
# cd /usr/kvm/mdec
# installboot -v /mnt/boot bootsd /dev/rsd0a
# halt
Booted it of its internal disk, and everything worked fine.
