Using Your Mainboard – 2.11
The CPU Retention Modules
The Pentium II CPU requires a mounting frame that attaches
to the mainboard to guide the CPU during installation and secure
it to the mainboard. This frame is called a “retention module”
and two are supplied with the mainboard. If you received this
mainboard installed in a system, at least one retention module
will already be installed. If you purchased the mainboard to in-
stall yourself, you will need to install a retention module on the
mainboard before you install the board in a system case.
Each module comes with two mounting brackets which in-
sert through holes in the mainboard from the underside. The mod-
ule is simple to install and will require either a flat-head or Philips-
head screw driver. To install the module do as follows:
1. Take precautions against static electric discharge before you
start. It is best to have an anti-static surface to place the main-
board on while you work on it and also an anti-static wrist
strap. If you don’t have an anti-static surface to work on, place
the board on the anti-static bag it comes in. If you don’t have
a wrist-strap (inexpensive and available at electronics stores),
try to touch something metal, perhaps the system case, before
you touch the mainboard.
2. The two mounting brackets insert through mounting holes in
the mainboard. The holes are at the four corners of each Slot 1
CPU slot. Press the two mounting bolts on each bracket
through the holes in the mainboard so that they protrude
through the board. You may need to push a little to seat them.
3. The module slides over the Slot 1 CPU slot. You have to ori-
ent it correctly for it to sit flat on the mainboard. Look at the
left end of the slot (as in the mainboard illustration in Section
1). There is an orientation foot on the slot that slides into the
orientation notch on the retention module. Look at the mod-
ule and find the notch. Orient the module to the CPU slot.
4. Slide the retention module over the CPU slot. If you have it
oriented correctly it will slide on easily and sit flat on the board.
The retaining nuts mounted in the module should fit over the
mounting bolts that protrude through the mainboard.
