The MBR partition entries start at offset 446, there are four entries
of 16 bytes each, followed by a 0x55 0xAA signature.  This collides
with SRM's bootstrap size, sector number, 0x0, and checksum longs at
the end of the first sector.

Only if booting from (ARC through) MILO.  When booting from SRM,
it uses a BSD/DEC UNIX disklabel.
