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 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.
