Hardware Installation
IDE Disk Drive Connectors
The system board is equipped with a 40-pin (IDE 1) and a 44-pin
(IDE 2) IDE connectors. To prevent improper IDE cable installation,
the IDE 1 connector has a keying mechanism. The connector on the
IDE cable can be inserted into IDE 1 only if pin 1 of the cable
connector is aligned with pin 1 of IDE 1.
The 40-pin IDE 1 connector is used for connecting 3.5” hard drives
while the 44-pin IDE 2 connector is used for connecting 2.5” hard
drives (2.0 pitch).
Each IDE connector supports 2 devices, a Master and a Slave. Use
an IDE ribbon cable to connect the drives to the system board. An
IDE ribbon cable have 3 connectors on them, one that plugs into an
IDE connector on the system board and the other 2 connects to
IDE devices. The connector at the end of the cable is for the Master
drive and the connector in the middle of the cable is for the Slave
drive.
