Connecting Floppy Drives (AHA-2742W and
AHA-2744W Only)
Floppy disk drives are connected to the host adapter by a
34-pin floppy ribbon cable with a 34-pin header connec-
tor. Up to two floppy diskette drives can be connected to
the host adapter.
When connecting your floppy drives, make sure to
maintain pin-1 orientation as previously described in
Connecting Internal SCSI Devices.
Note:
If you are not using the floppy controller on the
AHA-2742W and AHA-2744W, be sure to disable it by remov-
ing the jumper connector on jumper J1.
The AHA-2742W and AHA-2744W support only floppy pri-
mary address 3F0h - 3F7h. The IRQ channel is hard-wired for
channel 6 and the DMA channel is hard-wired for channel 2.
