9) Primary (Blue) / Secondary IDE Connectors

(40-1 pin PRIMARY IDE/SECONDARY IDE)

(40-1 pin PRIMARY ATA100/SECONDARY ATA100)

These connectors support the provided IDE hard disk ribbon cables. Connect

the cable’s blue connector to the motherboard’s primary (recommended) or sec-

ondary IDE connector, and then connect the corresponding gray connector to

your UltraDMA/100 / UltraDMA/66 slave device (hard disk drive) and the black

connector to your UltraDMA/100 / UltraDMA/66 master device. It is recom-

mended that non-UltraDMA/100 / Ultra/66 devices be connected to the second-

ary IDE connector.

NOTE: UltraDMA/100 is backward compatible with DMA/66, DMA/33, and

DMA and with existing DMA devices and systems so there is no need to upgrade

current EIDE/IDE drives and host systems.

If you install two hard disks, you must configure the second drive to Slave mode

by setting its jumper accordingly. Refer to your hard disk documentation for the

jumper settings. BIOS now supports specific device bootup (see 4.6 Boot Menu).

(Pin 20 is removed to prevent inserting in the wrong orientation when using

ribbon cables with pin 20 plugged). If you have more than two UltraDMA/100

/ UltraDMA/66 devices, you will need to purchase another UltraDMA/100 /

UltraDMA/66 cable.

NOTE: The hole near the blue connector on the UltraDMA/100 / UltraDMA/66

cable is intentional.

TIP: You may configure two hard disks to be both Masters with two ribbon

cables – one for the primary IDE connector and another for the secondary IDE

connector. You may install one operating system on an IDE drive and another on

a SCSI drive and select the boot disk through 4.6 Boot Menu.
