    Maybe, but if a PC can boot that way, why couldn't an OFW machine? I
would think it possible, if OFWBOOT was re-written, but that's much larger
project. Doesn't OFW load OFWBOOT, and then OFWBOOT uses OFW to load the
kernel into a certain memory segment and then execute it? OFW has an "eject"
word that will eject the floppy, I would think you could just take the two
kernel segments, put them "together" and then execute it with OFW. On the
flip side, it's a nearly pointless project, as new-world machines don't have
floppies and old-world ones don't need USB necessarily.

    Well, I've been told that MkLinux (and now Linux-NuBus PPC on
SourceForge?) has a swim3 driver that would be mostly drag and drop into
NetBSD, provided the author(s) don't object. However that still wouldn't
help us load the kernel, unless there was a two stage booter. A two stage
booter would be nice, because it could pave the way to booting off of a
CCD/RAID/CD-ROM on MS-DOS, HFS/HFS+, ISO, UDF

    Snapshot = good   Heh, well macppc isn't as far behind as pmax. I don't
think there has been a pmax snapshot since December 6th of '99 (1.4P).
