Asus P4SGX-MX - Manual (Page 26)

1-16 Chapter 1: Product introduction
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. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)
This connector supports the provided UltraDMA133/100/66 IDE hard disk ribbon
cable. Connect the cable’s blue connector to the primary (recommended) or
secondary IDE connector, then connect the gray connector to the
UltraDMA133/100/66 slave device (hard disk drive) and the black connector to
the UltraDMA133/100/66 master device. It is recommended that you connect
non-UltraDMA133/100/66 devices to the secondary IDE connector. If you install
two hard disks, you must configure the second drive as a slave device by setting
its jumper accordingly. Refer to the hard disk documentation for the jumper
settings. BIOS supports specific device bootup. If you have more than two
UltraDMA133/100/66 devices, purchase another UltraDMA133/100/66 cable.
You may configure two hard disks to be both master devices with two ribbon
cables – one for the primary IDE connector and another for the secondary IDE
connector.
Pin 20 on each IDE connector is removed to match the covered hole on the
UltraDMA cable connector. This prevents incorrect orientation when you
connect the cables.
