it is next to the power connector of the drive. The primary IDE connector is black; the
secondary IDE connector is white. In most cases, this is the proper way of connecting
your IDE cable to the hard drive. Figure 2-9 on the next page shows the IDE cable
properly connected to the motherboard. Contact your hard disk drive manufacturer or
documentation for more information.
ATA-66/100 IDE hard drives require a special 80 pin IDE cable* which has additional
grounding wires. The cable is included in the motherboard package, and is required when
!
using ATA-66/100 drives. This cable will also support all legacy IDE drives. Note: The
BLUE end of the ATA-100 cable* must connect to the motherboard. Only Tyan-
approved cables will work on this motherboard. If you are using an existing case
important!
with old cables, your system may not function properly.

Some symptoms of incorrectly installed HDDs are:
•
Hard disk drives are not auto-detected: may be a Master / Slave problem or a bad
IDE cable. Contact your vendor.
•
Hard Disk Drive Fail message at bootup: may be a bad cable or lack of power going
to the drive.
•
No video or beeps on bootup: usually means the cable is on backwards.
•
Hard drive lights are constantly on: usually means bad IDE cable or defective drives /
motherboard. Try another HDD.
•
Hard drives do not power up: check power cables and cabling. May also be a bad
power supply or IDE drive.
*
ATA-100 cables are identical to ATA-66 cables, therefore they are backward
compatible
