I setup a new drive
and sliced/diced it and then mounted and copied over
all the data (via a dump and pipe to restore).

Rsync was then run against the master to the new drive
and all matches fine.

then I tried to installboot via:
installboot -v -o timeout=5 /dev/rwd1a /usr/mdec/bootxx_ffsv1

and it accepted it:
File system:         /dev/rwd1a
Primary bootstrap:   /usr/mdec/bootxx_ffsv1
Preserving 51 (0x33) bytes of the BPB
Boot options:        timeout 5, flags 0, speed 9600, ioaddr 0, console pc


But when I try to boot off of the new drive:

MISSING OPERATING SYSTEM (right after the bios POST)

What step(s) did I miss?

thanks in advance!
