What was on the disk before?
The BPB (bios parameter block) is the area of the boot partition sector (63 here)
that the 'jmp' instruction at the start of the sector skips.
It tends to contain info about the filesystem.
sysinst should probably specify -f, especially if it knows
the fs is a netbsd one.
