Hmmm... What FreeBSD version are you using? I had assumed 4.x,
because that's what I'm using. It may well be the case that the
sample mbr has been moved somewhere else in the filesystem.
Checking the fdisk(8) and boot0cfg(8) man pages for clues doesn't
confirm that though.
The mbr should be a 512 byte file generated from the assembler sources
