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.
