Installing a Motherboard

Set the jumpers

Motherboards come with jumpers which can adjust some infrequently changed settings on the motherboard. These include bus speed, multiplier and voltage. Most modern day motherboards control these settings through the CMOS chip.

Align the I/O shield

You may need to adjust the the input / output shield with the case to make sure they are aligned. You may also need to use the I/O shield which came with the case rather than the motherboard.

Fans

Most motherboards support one or more fans that plug directly into the three or four wire pins-outs. They run on 12v and also enable the motherboard to monitor the fans status. If it stops working the motherboard can alert the operating system.

Front Panel Connections

The last step is to connect up the front panel connections, these include;
– Power button
– Hard drive activity light
– Power LED
– USB Ports
– Audio Ports

The LEDs have a positive and negative leg/wire so if they don’t work one way try the other. When in doubt guess (yep – it won’t damage the computer at this point). You don’t actually need any of these cables for the computer to run, they are cosmetic.
