10) Primary (Blue) / Secondary IDE Connectors
(40-1pin PRIMARY/SECONDARY IDE)
These connectors support the provided UltraDMA/66 IDE hard disk ribbon cable.
Connect the cable’s blue connector to the motherboard’s primary (recommended)
or secondary IDE connector, and then connect the gray connector to your
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 accord-
ingly. Please refer to your hard disk documentation for the jumper settings. BIOS
now supports specific device bootup. (Pin 20 is removed to prevent 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 the BIOS
IMPORTANT: UltraDMA/100 IDE devices must use a 40-pin 80-conductor IDE
cable for 100 MBytes/second transfer rates.
