B50 boot options

[T <bobs%thelibertytree.org@localhost>]

Two of these machines have landed in my possession and I'm trying to 
figure out the best hardware setup to make them usable. The current plan 
is to add a PCI USB 2.0 card (with internal connectors) in the second PCI 
system slot. Connected to that will be an internal USB-to-SATA adapter 
with a 2.5 inch SATA enclosure (hosts M.2 SATA type SSD sticks).

For booting, the existing 1.44 floppy would be replaced with a GoTek 
floppy emulator, ideally to use as the primary boot device since the 
firmware likely wont be able to boot the USB connected SSD. I have a 
similar setup for a PReP machine, but it uses a SCSI2SD hardware emulator 
as the boot device. An UltraSCSI emulator doesn't seem like a viable 
option, so the GoTek seems to be the best option, but I'm uncertain if the 
ofppc machines can boot NetBSD from a floppy drive.

Has anyone successfully used the floppy drive as a way to boot to a USB 
drive on a ofppc machine? On the PReP machine, building the primary boot 
image required a custom stripped down kernel so it could boot (some sort 
of 2MiB limitation), but in this case for a floppy image, it will need to 
be even smaller I suspect.
