Choosing a Case
The mainboard complies with the specifications for the micro-ATX
system case, although it can also be installed in most full-size ATX case
designs. The micro-ATX specifications include a maximum size of 9.6” x
9.6” (244mm x 244mm), a reduced number of expansion slots, and
support for a smaller power supply unit.
Some features on the mainboard are implemented by cabling connectors
on the mainboard to indicators and switches on the system case. Ensure
that your case supports all the features required. The P6IWT-Me
mainboard can support one or two floppy diskette drives and four
enhanced IDE drives. Ensure that your case has sufficient power and
space for all the drives that you intend to install.
The mainboard has a set of I/O ports on the rear edge. Ensure that your
case has an I/O template that supports the I/O ports and expansion slots.
How to Set Jumpers
A jumper consists of two or more pins mounted on the mainboard. Some
jumpers might be arranged in a series with each pair of pins numbered
differently. Jumpers are used to change the electronic circuits on the
mainboard. When a jumper cap is placed on two jumper pins, the pins
are SHORT. If the jumper cap is removed (or placed on just a single pin)
the pins are OPEN.
This illustration shows a 2-pin jumper. When the
jumper cap is placed on both pins, the jumper is
SHORT. If you remove the jumper cap, or place the
jumper cap on just one pin, the jumper is OPEN.
