3. IDE connectors (40-1 pin PRI_IDE[blue], SEC_IDE [white)

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.

• Refer to the hard disk drive label or documentation when setting

the device as master or slave.

• 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.

4. Backplane SMBus connector (6-1 pin BPSMB1)

This connector allows you to connect SMBus (System Management

Bus) devices. Devices communicate with an SMBus host and/or other

SMBus devices using the SMBus interface.
