9) Primary (Blue) / Secondary IDE Connectors (Two 40-1pin IDE)

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

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

ary IDE connector, and then connect the gray connector to your UltraDMA/100

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

master device. It is recommended that non-UltraDMA/100 devices be connected

to the secondary IDE connector. If you install two hard disks, you must config-

ure the second drive to Slave mode by setting its jumper accordingly. Please

refer to your hard disk documentation for the jumper settings. BIOS now sup-

ports specific device bootup (see 4.6 Boot Menu). (Pin 20 is removed to pre-

vent inserting in the wrong orientation when using ribbon cables with pin

20 plugged).

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.

IMPORTANT: UltraDMA/100 IDE devices must use a 40-pin 80-conductor IDE

cable for 100MByte/sec transfer rates.

write activity by devices connected to the Primary or Secondary IDE connectors

will cause the LED to light up.

TIP: If the case-mounted LED does not

light, try reversing the 2-pin plug.
