8) IDE Connectors (40-1 pin PRIMARY/SECONDARY/THIRD/FOURTH IDE)
These connectors support the provided UltraDMA/66 and UltraDMA/33 IDE
ribbon cables. For the UltraDMA/66 IDE cable, connect the single end to either
the third or fourth IDE connector and connect the two plugs at the other end to
your hard disk(s). If you install two hard disks, you must configure the second
drive to Slave mode by setting its jumper accordingly. Refer to the documenta-
tion of your hard disk for the jumper settings. BIOS now supports SCSI device
or IDE CD-ROM bootup (see Boot Sequence in 4.6 Boot Menu).
NOTES:
1. Pin 20 is removed to prevent inserting in the wrong orientation when using
ribbon cables with pin 20 plugged.
2. 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 Boot Sequence in 4.6 Boot Menu. If you
have more than two UltraDMA/66 devices, you will need to purchase another
UltraDMA/66 cable.
IMPORTANT: For UltraDMA/66 IDE devices to run, a 40-pin 80-conductor IDE
cable must be used. You will also need to make sure that Onboard PCI ATA 66
Chip Enable is enabled in the BIOS, see 4.4.1 Chip Configuration.
