10. IDE Connectors (40-1 pin PRI_IDE / SEC_IDE, PRI_ATA133)
Three connectorS support the UltraDMA133/100/66 IDE hard disk ribbon
cable provided with the motherboard. Connect the cable's blue connector
to the PRI_IDE (recommended) or to the SEC_IDE connector; then
connect the gray connector to the UltraDMA133/100/66 slave device (hard
disk drive) and the black connector to the UltraDMA133/100/66 master
device. It is recommended that non-UltraDMA133/100/66 devices be
connected to the secondary IDE connector. If installing two hard disks,
configure the second drive as a slave device; set the slave hard disk
jumper according to the HDD instructions.
~ The PRI_ATA133 connector supports only one hard disk drive for use
in a RAID array. The PRI_ATA133 connector supports either RAID1/0 in
combination with either of the Serial ATA connectors. (See pages 37
and 82 for more information about RAID.)
~ BIOS supports specific device bootup. If more than two
UltraDMA133/100/66 devices are used, purchase another UltraDMA133/
100/66 cable. It is possible to configure two hard disks as master devices
by using two separate ribbon cables, one for the primary IDE connector,
and another for the secondary IDE connector.
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.

P4S8X IDE Connectors
1. For UltraDMA133/100/66 IDE devices, use an 80-conductor
IDE cable. The UltraDMA/66 cable included in the motherboard
package also supports UltraDMA133.
2. Always connect ribbon cables with the red stripe to Pin 1 on
the connectors. Pin 1 is usually on the side closest to the power
connector on hard drives and CD-ROM drives, but may be on the
opposite side on floppy disk drives.
