  The device is /dev/fd0a (block device) or /dev/rfd0a (character device).
Also note that NetBSD only supports the AmigaDOS track format - it can not
read or write MSDOS track format yet.

  The NetBSD driver does support high-density drives - but I've only
verified that it works on my A4000.  The driver automatically detects a
high-density floppy by the ID code sent by the drive.  [I think there may
still be a problem when switching between densities - it may take a couple
of tries before it gets the correct density set.]  Since I don't have a
high-density drive on my A2000, I am unable to verify that the driver will
work for other high-density drives.  [If anyone would be willing to donate
or loan me a high-density drive, I could probably get the driver working
if there is currently a problem.]

  If the drive does not identify itself as a high-density drive, then
the driver would have to be modified to explicitly use the high-density
parameters.  This could be done using the minor number and the 'b'
"partition" (i.e. /dev/rfd0b could be used to explicitly indicate a
high-density drive).
