2.9.1 Connecting the floppy drive
1.
Plug the 34-pin flat-cable connector into CN13. 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 5º" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable connec-
tor. If you are connecting a 3¾" 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. Also, 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 docu-
mentation that came with the drive for more information. The B:
drive can be attached to the connectors in the middle of the cable as
described above.
2.10 LPT1 (primary parallel port) connectors (CN28/
CN29)
The primary parallel printer port is located at the rear edge of the board,
and has a DB-25 connector. This printer port is typically used to connect
a printer via an adapter cable. LPT1's IRQ setting is defined as IRQ7.
You can select Normal/EPP/ECP for LPT1, and enable/disable it in BIOS
(see Chapter 4). There is another internal parallel port connector, CN29,
also available.
2.11 LPT2 (secondary parallel port) connector (CN30)
The secondary parallel port is located next to and on the inner side of the
primary parallel port. This secondary port has a 26-pin box header.
LPT2ís IRQ setting is defined as IRQ9. You can select Printer/EPP/ECP/
SPP for LPT2, and enable/disable it in BIOS (see Chapter 4).
