IDE Hard Drive Connectors (CN7)

If customers have (Neccessity) to use ATA-100 HDD and ATA-33 CABLE you must alter two settings in the Award BIOS. The two settings are IDE Primary Master UDMA and IDE Primary Slave UDMA. Set these two functions as disabled.

Primary IDE Hard Drive Connector (CN7)

You can attach up to three Enhanced Integrated Device Electronics hard disk drives to the mainboard's internal controller. The main- board's IDE controller uses a PCI local-bus interface. This advance interface supports faster data transfer and allows the IDE hard drive to exceed 528 MB.

Connecting the hard drive

Connecting drives, their done in a daisy-chain fashion and requires one of the three cables, depending on the drive size. 1.8" and 2.5" drives need one 44-pin to two 44-pin flat cable connector. 3.5" drives use one 44-pin to two 40-pin connector.

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

1.Connect one end of the cable to CN7. Make sure that the red (or blue) wire corresponds to pin 1 on the connector, which is marked and connectors are slotted.

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 drives. (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 be connected to either end of the cable. The pin definitions for this section are listed on the next page.
