Sorry, the floppy drive needs it's buffers in CHIP RAM.  The reason is that the
trackdisk.device uses the BLITTER to do the MFM encoding of the data that is
then written to the drive.  I guess this is a testimony to the flexibility and
power of the Amiga's custom chip set :-)...
     I would recommen using a program like FACC II for your floppy cacheing.
It works a WHOLE lot better than Addbuffers (or adding more buffers via the
Mountlist).
