2.8 Connectors

This section describes and illustrates the internal connectors on the

motherboard.

Always connect ribbon cables with the red stripe to Pin 1 on the

connectors. Pin 1 is usually on the side closest to the power connector

on hard drives and CD-ROM drives, but may be on the opposite side

on floppy disk drives.

1. Floppy disk drive connector (34-1 pin FLOPPY)

This connector supports the provided floppy drive ribbon cable. After

connecting one end to the motherboard, connect the other end to the

floppy drive. (Pin 5 is removed to prevent incorrect insertion when

using ribbon cables with pin 5 plug).

4. SMB2.0 (two 3-pin SMB20)

These jumpers allow you to enable or disable the SMBus 2.0 feature

supported on the motherboard. By default, pins 2-3 are shorted

(jumper caps on) to disable the feature. If you wish to install PCI

devices that comply with SMBus 2.0 specification, move the jumper

caps to pins 1-2 of both jumpers to enable the SMBus 2.0 feature.
