Connecting Ide And Floppy Drives - TYAN THUNDER I840 User Manual

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. Figure 2.4 (see right) shows the
IDE cable properly connected to the motherboard. Con-
sult the documentation that came with your device, or
contact the device's manufacturer for details on its instal-
lation. Also see Figure 2.5 (see picture to the right) for
an example of an HDD with the IDE cable installed. ATA-
66 IDE HDDs require a special 80-wire, 40-pin IDE cable
which has additional grounding wires, and may or may
not have a notch near the blue connector. The cable is
included in the Thunder i840 motherboard package. The
ATA-66 cable is also upwards compatible with ATA-100
devices, and backwards compatible with ATA-33 and
Legacy IDE HDDs.
The BLUE end of the ATA-66 cable must connect to the motherboard. The black con-
nector on the ATA-66 cable is for the master HDD, and the grey connector is for the
slave HDD. See Figure 2.4 for an example of cable installation on the motherboard.
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 that were included with your mother-
board).
Some symptoms of incorrectly installed HDDs are...

Hard Disk Drive Fail message at bootup

wards.
