AMD PCM-5820 manual IDE hard drive connector CN11, Connecting the hard drive

2.7IDE hard drive connector (CN11)

The built-in Enhanced IDE (Integrated Device Electronics) controller supports up to two IDE devices, including CD-ROM drives, tape backup drives, a large hard disk drive and other IDE devices. It also supports faster data transfer, PIO mode 3, mode 4, and Ultra DMA 33 mode.

2.7.1 Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires one or two cables, depending on the drive size. All required cables are included in your PCM-5820 Series package. 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. However, the required connectors are not included in the PCM-5820 Series package.

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

1.Connect one end of the cable to CN11. 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).

2.Plug the other end of the cable to 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 connector.)

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 just one drive, set it as the master.
