Actually, the MBR format is used on many other platforms.
fdisk(8) is built on the following NetBSD platforms:
	amd64 arc bebox cobalt hpcarm hpcmips hpcsh i386
	macppc mvmeppc netwinder ofppc playstation2 prep

Most platforms just use the partition table at bytes 446-509
and the magic number 0xAA55 at bytes 510-511.

I've documented some of the format in src/sys/sys/bootblock.h=20

Luke.
