SYMPTOMS
Fifth Generation Systems Fastback and Fastback Plus run very slowly in
Windows NT.
CAUSE
This problem occurs because Fastback directly programs the floppy disk
controller (FDC) to increase the speed of floppy disk reads and
writes.
Unfortunately, Windows NT has to trapping all input and output in the
virtual DOS machine (VDM), which causes the floppy reads and writes to
be slower instead of faster.
