The problem is that the RZ1000 steals buffers from the floppy controler,
which is fine if you can garentee that the floppy driver is never touched
while the buffers are in use (by the RZ1000). This is the case under
dos, and windows (tho not with the 32 bit drivers on I think). It will
only effect Linux if you use the floppy drive, and run the ide with
interupts unmasked (you have to do 'hdparm -u 1 /dev/hd?'). Don't worry
about it, just don't unmake the interupts (makes the disks go faster, but
only when the ide disk is loaded). Well that's what I rember anyway ....
