What flavor of hard drive controller?  If generic IDE, yes.  If SCSI or
SATA (or 'fancy' IDE), only if the original and replacement use the
same driver module (if a PCI SCSI card, move the SCSI controller with the

If the controller is *different*, remake the initrd and add the proper
driver for the replacement board:

mkinitrd --with=<mumble> -f /boot/initrd-`uname -r`.img `uname -r`

<mumble> is the driver module for the new board's HD controler.

(Do this on the original system.)

You can use a livecd to determine that.

You *could* just do the transplant and then use the install CD (or a
live CD) in rescue mode to 'fix' the initrd.
