Board Installation
Drive A: is usually attached to the end of the cable with the twist in it. Drive B:
is usually connected to the middle of the cable. Refer to your installation
instructions or call your dealer if you are unsure about attaching floppy drives.
Refer to Figure 2-23 for a detailed anatomy of the floppy cable. Remember, you
can only have 2 floppy drives connected at any given time.
The color stripe on the cable should face toward the top of your chassis, or
toward the big white B printed on the motherboard. Please refer to your
documentation for proper installation.
Some symptoms of incorrectly installed floppies are:
•
Floppy drives are not detected: usually caused by faulty cables,
backward cables, or a bad floppy or motherboard. Try another single
floppy drive to verify the problem or try another cable. Also, check to
see if the onboard floppy is enabled in the BIOS.
•
Floppy Drive Fail message at bootup: the cable, floppy, or
motherboard may be faulty. Try another cable or floppy drive to
verify.
•
Light on the floppy is on constantly: a dead giveaway that the cable
is on backwards. Reverse the cable at the motherboard end and try
again.
6. Connecting the Power Supply
Tyan recommends using an ATX power supply that conforms to industry
standard revision 2.01. The Tomahawk BX/A+ motherboard comes equipped
with one onboard power connector.
Figure 2-24 on the following page shows an ATX power connector. When
plugging in the power connector, make sure that the plastic clip on the power
connector is aligned with the plastic tab on the onboard connector (see Figure
2-25 on the following page).
Make certain that you do not miss any pins because if you do, you will void
your warranty and cause damage to yourself or your motherboard when you
turn the system on. After connecting the power, make sure the connector is
seated firmly into its socket so it will not become loose or fall off when the
computer is jostled or moved.
