1.

Plug the 34-pin flat-cable connector into CN6. 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 5.25” 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 3.5” floppy drive, you may have trouble determin-
ing which pin is number one. Look for a number printed on the circuit 
board indicating pin number one. In addition, the connector on the floppy 
drive 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. 
In case you need to make your own cable, you can find the pin assign-
ments for the board’s connector in Appendix C.

Normally, the parallel port is used to connect the card to a printer. The 
PCI-6871 includes a multi-mode (ECP/EPP/SPP) parallel port accessed 
via CN2 and 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. 

The PCI-6871 board provides a keyboard connector that supports both a 
keyboard and a PS/2 style mouse. In most cases, especially in embedded 
applications, a keyboard is not used. If the keyboard is not present, the
