Step 5 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 Action
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 screen.
Warning
If using metallic screws, make sure you use them only in the
plated mounting holes.
If using metallic screws, make sure the head of the screw fits
completely inside the plated mounting holes.
