2.10 Connecting IDE and Floppy Drives

A variety of IDE and ATAPI-compliant devices can be installed on this motherboard, such as hard disk

drives (HDDs) and CD-ROMs.

Please keep in mind that on this motherboard, the pri- mary IDE connector is BLACK, and the secondary IDE

connector is WHITE. See the picture to the rightfor an

example of the IDE cable properly connected to the motherboard, with the BLUE end of the IDE cable installed on the motherboard.

Pin 1 on the IDE cable is usually denoted by a red or col- ored stripe down one side of the cable. That side of the cable must match Pin 1 on the motherboard’s IDE con- nector. There will also be a key pin on the cable that matches with a notch in the IDE connector, to ensure proper installation. Consult the documentation that came with your IDE/ATAPI device, or contact the device’s manufacturer for more details on installation.

Please note that UltraDMA-100/66 IDE HDDs require a special 80-wire cable (see picture at right), which has additional grounding wires. This cable has been included with this motherboard for your convenience. The UltraDMA-100/66 cable is backwards compatible with UltraDMA-33 and legacy IDE HDDs.

NOTE:

Only Tyan-approved cables are recommended for this motherboard. If you are using an existing configuration with older cables, your system might not function properly. Use only Tyan-approved cables (i.e. the ones included with your new motherboard).

Some symptoms of incorrectly installed HDDs are...

HDDs are not auto-detected	May be a Master/Slave configuration problem, bad
	IDE cable, or BIOS mis-configuration. Consult the
	HDD documentation or contact your HDD vendor.
Hard Disk Drive Fail message at bootup	May be a bad cable or lack of power going to the
	drive. Check the cables for damage and bad con-
	nections.
No video or beeps during bootup
	Usually means the cable was installed backwards.
HDD lights are constantly on	Bad IDE cable or defective drives/motherboard. Try
	another HDD, or contact your HDD vendor.

	power supply or IDE drive problem.
