Most PC BIOSes (if not all) will not boot from a disk if the first block does not have the 0xAA55 signature. Indeed, they will not boot without a valid MBR. Have you ever seen such a case ? Or does this discussion apply to PC98 (from which I have no info, and don't know if the above is still true) and Alpha ports ? // 2. Wait for fixes. // 3. Same as for cases where the whole disk is not used for FreeBSD - edit // /etc/fstab.
