11)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. 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. Please refer to your hard disk documenta- tion for the jumper settings. BIOS now supports specific device bootup (see 4.6 Boot Menu). (Pin 20 is removed to prevent wrong orientations).

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.
