3. HARDWARE SETUP
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. 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
configure the second drive to Slave mode. Please refer to your hard disk docu-
mentation 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.
