IBM 6345, 2194, 2193 manual Guidelines for connecting IDE/ATA signal cables

In your computer, the IDE and diskette connectors on the system board and cables have guides that allow the cable to be inserted one way only.

Guidelines for connecting IDE/ATA signal cables

Your system board has two connectors for attaching IDE/ATA signal cables. You can install two IDE/ATA drives to each of these connectors, if you have the proper cables. When two drives are attached to one connector, one drive must be the master device, and the other the slave device. Jumper settings on the drives determine which drive is the master and which is the slave.

The hard disk that came installed in your computer is attached to IDE connector 1 and is set as a master device. If your computer came with a CD-ROM drive, it is attached to IDE connector 2 and is set as a master device.

These are the general guidelines for IDE/ATA signal cable connections:

•If only one drive is attached to a connector, it must be set as a master device.

•On each connector, there can be only one drive set as the master device and one drive set as the slave device.

•If a hard disk shares the same connector with a drive that requires a software device driver (such as a CD-ROM drive), the hard disk must be set as the master device and the CD-ROM must be set as the slave device.
