Chapter 1: Product introduction

IDE connector (40-1 pin PRI_EIDE)

The onboard IDE connector is for the Ultra DMA 133/100 signal cable. There are three

connectors on each Ultra DMA 133/100 signal cable: blue, black, and gray. Connect

the blue connector to the motherboard’s IDE connector, then select one of the following

modes to configure your device.

• Pin 20 on the IDE connector is removed to match the covered hole on the Ultra DMA

cable connector. This prevents incorrect insertion when you connect the IDE cable.

• Use the 80-conductor IDE cable for Ultra DMA 133/100 IDE devices.

If any device jumper is set as “Cable-Select,” ensure that all other device jumpers have the

same setting.

LPT connector (26-1 pin LPT)

The LPT (Line Printing Terminal) connector supports devices such as a printer. LPT is

standardized as IEEE 1284, which is the parallel port interface on IBM PC-compatible

computers.
