Identify an empty expansion slot.
3

Align the bus connector on the bottom of the host
adapter with the slot and carefully insert it into
the slot. Attach the host adapter bracket to the PC
chassis with the expansion slot cover screw.
Note:
Do not replace the PC chassis cover or
reconnect the power yet.

Controlling Floppy Drives (AHA-1532P only)
If you do not want to use the onboard floppy drive
controller on your AHA-1532P host adapter, set
sw5
to On to disable it. If you connect the floppy drives to
the AHA-1532P floppy controller you must disable
other floppy controllers in the PC. See your PC
documentation.
