9) Primary (Blue) / Secondary IDE Connectors
(40-1 pin PRIMARY ATA100 SECONDARY ATA100)
(40-1 pin PRIMARY IDE/SECONDARY IDE)
These connectors support the provided IDE hard disk ribbon cables. Connect
the cable’s blue connector to the motherboard’s primary (recommended) or sec-
ondary IDE connector, and then connect the corresponding gray connector to
your UltraDMA100 / UltraDMA/66 slave device (hard disk drive) and the black
connector to your UltraDMA/100 / UltraDMA/66 master device. It is recom-
mended that non-UltraDMA/100 / UltraDMA/66 devices be connected to the
secondary IDE connector.
NOTE: UltraDMA/100 is backward compatible with DMA/66, DMA/33, and
DMA and with existing DMA devices and systems so there is no need to upgrade
current EIDE/IDE drives and host systems.
If you install two hard disks, you must configure the second drive to Slave mode
by setting its jumper accordingly. Refer to your 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 orienta-
tion when using ribbon cables with pin 20 plugged). If you have more than
two UltraDMA100 / UltraDMA66 devices, you will need to purchase another
UltraDMA100 / UltraDMA66 cable.
NOTE: The hole near the blue connector on the UltraDMA100 / UltraDMA66
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.

(usually zigzag) on the IDE
ribbon cable to PIN 1.

IMPORTANT: UltraDMA66 and UltraDMA100 IDE devices require a 40-pin
80-conductor cable to be enabled.
