I have a new Winbook XL2 notebook which has a ATAPI LS-120
Superdisk floppy (120 MB and compatible with 1.44 MB).  It
does not have a traditional floppy drive (kernel bootup msg:
"floppy0: no floppy controllers found").

It can boot off the bootnet floppy fine, but if I want to do
an install that requires a supplemental disk (e.g., network
install that requires PCMCIA devices), install will ONLY
attempt to mount /dev/fd0, never /dev/hdd, which was the
original boot device.  A simple fix would be, upon failure
to mount fd0, to ask the user to mount from a list of
detected devices.
