Well, please bug him about the BIOS bug. ;-)

No such thing like ``no MBR''.  The MBR is by definition the very
first 512-byte record of a bootable drive.  It needs to have a 0x55aa
signature at the end in order to be recognized by the BIOS.  Some
BIOSes apparently try to be `smarter', and wanna imply more semantics
than this signature.  (Normally, the BIOS should just load an MBR that
has this signature onto address 0x7c0:0, and execute it.)
