ASUS PC-DL Deluxe motherboard 2-21
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 FLOPPY1)
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).
2. SMBus connector (6-1 pin SMB1)
This connector allows you to connect SMBus (System Management
Bus) devices. Devices communicate with an SMBus host and/or other
SMBus devices using the SMBus interface.

NOTE: Orient the red markings on
