Asus P4S533-X - 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.
