2. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)
This connector supports the provided UltraATA100/66/33 IDE ribbon cable.
Connect the cable’s blue connector to the primary (recommended) or secondary
IDE connector, then connect the gray connector to the UltraATA100/66/33 slave
device (hard disk drive) and the black connector to the UltraATA100/66/33 master
device. It is recommended that you connect non-UltraATA100/66/33 devices to the
secondary IDE connector. If you install two hard disks, you must configure the
second drive as a slave device by setting its jumper accordingly. Refer to the hard
disk documentation for the jumper settings. BIOS supports specific device bootup.
If you have more than two UltraATA100/66/33 devices, purchase another
UltraATA100/66/33 cable. You may configure two hard disks to be both master
devices with two ribbon cables – one for the primary IDE connector and another
for the secondary IDE connector.
Refer to the Parallel ATA and Serial ATA device configurations on the next page.
Important note when using legacy OS
Refer to page 1-22 on how to configure P-ATA and S-ATA devices if you
installed a legacy operating system (e.g. MS-DOS, Windows
® 98/Me/NT4.0 ® ).
1. Pin 20 on each IDE connector is removed to match the covered hole on the
UltraATA cable connector. This prevents incorrect orientation when you
connect the cables.
2. The hole near the blue connector on the UltraATA100/66/33 cable is
intentional.
3. For UltraATA100/66/33 IDE devices, use the 80-conductor IDE cable.
