dd copy of FreeBSD-7.2 won't boot

[Jim Flowers]

I have a remote server that was dd copied from one hard drive to another - 
essentially the same size.  The disk device name (ad4) is the same but the 
geometry for the new drive has a CHS of 969021/16/63

On booting it hangs at:

F1        FreeBSD
Boot:     F1

I copied the MBR with 'boot0cfg -B -opacket ad4' just to be sure but no joy.  
fbsd fdisk reports start 63, with CHS beg: 0/1/1 end: 1023/15/63.

Any help on direction to solve this?

Thanks.
