Sounds like the disk is missing the infamous boot block, no problem.
Check out the installboot command: I have used it a few times.  On 4.0.3
try

cd /usr/kvm/mdec
installboot -vlt /boot bootsd /dev/rsd2a

try 'man installboot' to find out exactly what it does Note pre 4.0
systems the installboot behaves slightly differently.
