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 B.

2.15 IDE connector(CN3,CN7)

The PCI-6886 provides two IDE channels to which you can attach up to

four Enhanced Integrated Device Electronics hard disk drives or

CDROM to the PCI-6886's internal controller. The PCI-6886's IDE con-

troller uses a PCI interface. This advanced IDE controller supports faster

data transfer, PIO Mode 3 or Mode 4, UDMA 33/66/100 mode.

Connecting drives is done in a daisy-chain fashion. It requires one of two

cables (not included in this package), depending on the drive size. 1.8"

and 2.5" drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"

drives use a 1 x 44-pin to 2 x 40-pin connector.

Wire number 1 on the cable is red or blue, and the other wires are gray.

Connect one end of the cable to CN3,CN7. Make sure that the red

(or blue) wire corresponds to pin 1 on the connector, which is

labeled on the board (on the right side).

Plug the other end of the cable into the Enhanced IDE hard drive,

with pin 1 on the cable corresponding to pin 1 on the hard drive.

(See your hard drive's documentation for the location of the con-

nector.)

If desired, connect a second drive as described above.

Unlike floppy drives, IDE hard drives can connect to either end of the

cable. If you install two drives, you will need to set one as the master and

one as the slave by using jumpers on the drives. If you install only one

drive, set it as the master.
