2.9.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN9. Make sure that the
red wire corresponds to pin one on the connector.
2. Attach the appropriate connector on the other end of the cable to
the floppy drive(s). You can use only one connector in the set. The
set on the end (after the twist in the cable) connects to the A: drive.
The set in the middle connects to the B: drive.
3. If you are connecting a 5¼” floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
If you are connecting a 3½” floppy drive, you may have trouble
determining which pin is pin number one. Look for a number
printed on the circuit board indicating pin number one. In addition,
the connector on the floppy drive connector may have a slot. When
the slot is up, pin number one should be on the right. Check the
documentation that came with the drive for more information.
If you desire, connect the B: drive to the connectors in the middle
of the cable as described above.
If you need to make your own cable, you can find the pin assignments
for the board’s connector in Appendix C.
2.10 Parallel port connector (CN12)
Normally, the parallel port is used to connect the card to a printer. The
PCM-9574 includes a multi-mode (ECP/EPP/SPP) parallel port,
accessed through CN12, a 26-pin flat-cable connector. You will need
an adapter cable if you use a traditional DB-25 connector. The adapter
cable has a 26-pin connector on one end and a DB-25 connector on
the other.
The parallel port is designated as LPT1 and can be disabled or
changed to LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
