Just install an MBR on one disk, and then use dd to copy it. A master boot
record is always 512 bytes long. Assuming you are using SATA disks and the
MBR was installed on the first, the command would be
# dd if=/dev/sda of=/dev/sdb bs=512 count=1
To test it, shut down cleanly {so the RAID integrity is maintained}, and
physically swap the drives.
