2. IDE connectors (40-1 pin PRI_IDE[blue], SEC_IDE [black) This connector supports the provided UltraDMA/100/66 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/100/66 slave device (hard disk drive) and the black connector to the UltraDMA/100/66 master device. It is recommended that you connect non-UltraDMA/100/66 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. 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. 1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional. 3. For UltraDMA/100/66 IDE devices, use the 80-conductor IDE cable. NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1. ® SEC_IDE PRI_IDE P4C800-E PIN 1 P4C800-E IDE Connectors PIN 1 Important note when using legacy OS Refer to page 2-24 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). 2-22 Chapter 2: Hardware information
