There will probably need to be at least two disks.  The first would be
HFS, and contain only one file - the bootloader should not have to deal
with a complete floppy driver!  The COFF format supports an embedded

The other disk could be ext2 formatted, or more like the PC version
(IIRC) a gzipped ramdisk.  This would need to be shrinkwrapped- no HFS
at all.  Fortunately, this can be produced even without MacOS -
ShrinkWrap can take raw files and write them to disk, given the proper
type/creator.  There's no meta-information in one of its existing file
formats.  Don't recall the type/creator off the top of my head though.

This would only work for Power Macs.  The other (PReP, CHRP)
architectures we support would require their own boot methods, and I
don't know much about that.
