The boot floppy is in the same format as macppc disks. There is a NetBSD
disklabel along with a hacked up macos partition table. The only valid
partition in this table is a "driver" partiton with knows how to load
ofwboot. ofwboot then knows how to read ffs filesystems and load the
kernel.

I think the boot floppies are real easy to use if you already have a
NetBSD box. I'm working on getting somethign easier for new users.

Take care,
