Tomcat i7221A S5151 Chapter 2: Board Installation
2.6 Mounting the Motherboard
Before installing your motherboard, ensure that your chassis is fully com patible. The Tomcat
i7221A S5151 motherboard conforms fully to the ATX specification. Your chassis should
include preinstalled mounting posts that match exactly with the mounting holes in the
motherboard. Lay the motherboard on top of the mounting holes to ensure that all the
necessary mounting posts exist in your chassis and that they match the mounting holes on
the motherboard.
Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable,
TYAN recommends using metal studs with screws that will fasten the motherboard more
securely in place.
See the diagram below for some examples of typical motherboard fixing studs.
TIP: Use metal studs if possible, as they hold the motherboard into place more securely than
plastic standoffs.

3. Lift the metal cover to expose the socket interior and place the socket in as shown.
4. Close the cover and return the locking lever to its locked position.
Cooling Fan Installation
After you have installed the processor, the heatsink should be installed to ensure that the
processor runs efficiently and does not overheat. Use the heatsink supplied for best results.
Follow these instructions to install the heatsink shown.
1. Apply some thermal compound (also called heatsink compound or thermal grease) to
the top of the processor. Try and apply a thin, even layer over the top of the processor.
2. Align the heatsink with the four holes around the processor socket.
3. Press the heatsink down until the four screws are se curely seated in the holes.
4. Use screw drive to secure the four screws.

To remove the heatsink you will need to twist each of the black locking pegs until they spring
up and unlock the heatsink from the motherboard.
Remember to connect the power supply for the fan to complete the installation.
Some heat sinks require a bracket to be installed beneath the motherboard before the heat
sink is placed on the top side of the motherboard. To install a heat sink like this:
1 Turn the motherboard upside down and place the rear bracket in position with the
mounting posts poking through the corresponding holes in the motherboard.
2 Turn the motherboard the right way up, holding the bracket in place.
3 Place the heat sink assembly on top of the processor.
It should match up with the mounting holes on the rear bracket.
4 Screw the heat sink assembly into place.
If there is a fan on the heat sink you will need to connect the power lead for the fan to
one of the fan power supply pin headers on the motherboard.

Colored cable denotes pin 1
2.9 Installing Drive Cables
TIP: IDE and FDD connectors are “keyed” to only allow insertion only one way. S5151
m otherboard has two on-board IDE channels, each supporting two drives.
IDE Cable
When connecting to an IDE cable to a drive, Pin 1 on the IDE cable
(usually designated by a colored wire) should be closest to the drive
power connector.
The blue end of the cable connects directly to the motherboard and the
black end of the connector goe s to the IDE device.
Serial ATA
Attaching Serial ATA cables to the Serial ATA connectors are illustrated below:
Plug in one end of the Serial ATA cable into the motherboard Serial ATA
connector, and the other end into the drive. Each standard Serial ATA cable has
two connectors, one at each end. Connectors are the same on both ends.
FloppyDrives
Floppy disk drive (FDD) cables are installed the same way as IDE cables. Usually connectors
are keyed to prevent insertion the wrong way. In most cases the cable should be inserted into
the drive with pin 1 closest to the power input. FDD cables usually have a single red wire that
marks pin 1. See the diagram below.
Symptoms of incorrectly installed floppy drives
Drive is not automatically detected
Drive Fail message at b oot up
Drive does not power on
Drive activity light is constantly on
Usually caused by faulty cables, cables put in
backwards or a faulty floppy drive. Try another
floppy drive or try replacing the cable. Check to
see if the onboard floppy controller is enabled in
the BIOS setup.
The cable, floppy drive or motherboard may be
faulty. Try another drive or cable.
Check power cable and cabling. A faulty power
supply or drive cable could be the problem.
Usually signifies that the cable on the drive is
inserted backwards. Reverse the cable at the
floppy drive end and try again.
