Installing the LSI21003

2.2.3.1 Making Internal SCSI Bus Connections

This section provides step-by-step instructions about making internal
SCSI bus connections. If you have no internal devices to connect,
proceed to Step 4.

Step 1.

Plug one end of a SCSI ribbon cable into an appropriate
connector, J2, J4, or J5. The example in

shows a

wide cable.

Channel A (J2 and J4) supports SE mode. Channel B (J5)
supports SE and LVD modes.
