3) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2)
These connectors support the provided UltraDMA/66 IDE hard disk ribbon
cable. Connect the cable’s blue connector to the primary (recommended) or
secondary IDE connector, then connect the gray connector to the UltraDMA/66
slave device (hard disk drive) and the black connector to your UltraDMA/66
master device. It is recommended that non-UltraDMA/66 devices be connected
to the secondary IDE connector. If you install two hard disks, you must configure
the second drive to Slave mode by setting its jumper accordingly. Refer to the
hard disk documentation for the jumper settings. BIOS now supports specific
device bootup (see 4.4.1 Advanced CMOS Setup). (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/66 devices, you need to purchase
another UltraDMA/66 cable.
NOTE: The hole near the blue connector on the 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 4.4.1 Advanced CMOS Setup.
IMPORTANT: UltraDMA/66 IDE devices must use a 40-pin 80-conductor IDE cable.
