3. HARDWARE SETUP 8) Game/MIDI Connector (Gold 15-pin GAME_AUDIO) (optional) You may connect game joysticks or game pads to this connector for playing games. Connect MIDI devices for playing or editing professional audio. Joystick/MIDI (15-pin female) 9) Primary (Blue) / Secondary (Black) IDE Connectors (Two 40-1pin IDE) These connectors support the provided UltraDMA/66 IDE hard disk ribbon cable. Connect the cable’s connector (usually blue) to the motherboard’s primary (rec- ommended) or secondary IDE connector, and then connect the gray connector to your UltraDMA/66 slave device (hard disk drive) and the black connector to your UltraDMA/66 master device.
It is recommended that non-UltraDMA/66 devices be connected to the secondary IDE connector. If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper accordingly. Please refer to your hard disk documentation for the jumper set- tings. BIOS now supports specific device bootup (see Advanced CMOS Setup ). (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 20 plugged). TIP: You may configure two hard disks to be both Masters with two ribbon cables – one for the primary IDE connector and another for the secondary IDE connector.
You may install one operating system on an IDE drive and another on a SCSI drive and select the boot disk through Advanced CMOS Setup . 3. H/W SETUP Connectors IMPORTANT: UltraDMA/66 IDE devices must use a 40-pin 80-conductor IDE cable for 66MBytes/s transfer rates. Secondary IDE Connector Primary IDE Connector NOTE: Orient the red markings (usually zigzag) on the IDE ribbon cable to PIN 1. ® CUA CUA IDE Connectors PIN 1 34 ASUS CUA User’s Manual
