Intel PCA-6175 manual Primary CN6 and Secondary CN7 IDE Connectors, Floppy Drive Connector CN13

2.1Primary (CN6) and Secondary (CN7) IDE Connectors

You can attach up to four IDE (Integrated Device Electronics) drives to the PCA-6175’s internal controller. The primary (CN6) and secondary (CN7) connectors can each accommodate two drives.

Wire number 1 on the cable is red or blue and the other wires are gray. Connect one end to connector CN6 or CN7 on the CPU card. Make sure that the red/blue wire corresponds to pin 1 on the connec- tor (in the upper right hand corner). See Chapter 1 for help finding the connector.

Unlike floppy drives, IDE hard drives can connect in either position on the cable. If you install two drives to a single connector, you will need to set one as the master and one as the slave. You do this by setting the jumpers on the drives. If you use just one drive per connector, you should set each drive as the master. See the documen- tation that came with your drive for more information.

Connect the first hard drive to the other end of the cable. Wire 1 on the cable should also connect to pin 1 on the hard drive connector, which is labeled on the drive circuit board. Check the documentation that came with the drive for more information.

Connect the second hard drive to the remaining connector (CN7 or CN6), in the same way as described above.

2.2Floppy Drive Connector (CN13)

You can attach up to two floppy disk drives to the PCA-6175's on-board controller. You can use any combination of 5.25" (360 KB/1.2 MB) and/or 3.5" (720 KB/1.44/2.88 MB) drives.

The card comes with a 34-pin daisy-chain drive connector cable. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a

34-pin flat-cable connector (usually used for 3.5" drives) and a printed circuit-board connector (usually used for 5.25" drives). You can use only one connector in each set. The set on the end (after the twist in the cable) connects to the A: floppy drive. The set in the middle connects to the B: floppy drive.
