[comp.sys.ibm.pc] Dual Speed Drives?

jewett@mcnc.org (Rusty Jewett) (05/31/89)

I have a Western Digital dual floppy/hard controller (2,7RLL 1:1 interleave).
One of the jumpers on the board is documented as a switch for dual speed/single
speed floppies.  What exactly does this mean?  Is a dual speed floppy one that
can write to two kinds of disks (e.g. a 1.44 Meg floppy drive)?

Many thanks in advance,
Rusty

P.S.  If it makes any difference, the controller is a 16 bit controller.
