Step 4 Install the Motherboard

The motherboard mounting hole pattern is the same as the mounting hole
pattern on the standard baby AT motherboard. Standoffs and mounting screws
are not supplied with the motherboard. The chassis manufacturer should supply
these parts.
Step
1 Place the chassis on an anti-static mat. Connect the chassis to ground
to avoid static damage during installation. Connect an alligator clip
with a wire lead to any unpainted part of the chassis. Ground the
other end of the lead at the same point as the mat and the wristband.
2 Rotate the chassis so the front is to the right, and the rear is to the
left. The side facing you is where the motherboard is mounted. The
power supply is mounted at the far end of the chassis.
3 Hold the motherboard, component-side up, with the edge with the
SIMM sockets toward you and the edge with the power supply
connector away from you. The keyboard, mouse, and video connectors
should be to the left.
4 Carefully slide the motherboard into the chassis. Make certain the
edge connectors fit the ports in the rear of the chassis. The
motherboard should rest level with the chassis.
5 Place the mounting screws in the holes provided and tighten them. If
necessary, shift the motherboard slightly to align the mounting holes
on the motherboard with the holes on the chassis. See the drawing on
the next page.
