Installation Procedure

Prepare the Mainboard
Prepare the main board by installing the Cyrix GXm processor and then installing
either one or two memory modules. This board supports the 200, 233, or 266 MHz
version of the Cyrix GXm processor. Finally, use the selection jumpers to configure
the board for the correct bus and clock speeds.

Install the Processor

1. Locate the zero insertion force (ZIF) SOCKET7 for the processor. On the socket
and on the processor, identify the pin 1 corner. You can identify the pin 1 corner
by noting that in the rectangular matrix of pins and holes on the socket and
processor, one pin and one hole is absent on the pin 1 corner.
2. Push the socket locking lever away from the socket to unhook it. Swing the lever
into the upright position.
3. Insert the processor into the socket taking care that you have matched the pin 1
corners. No force is required, and the processor should seat smoothly into the
socket.
4. Swing the locking lever down and hook it under the latch on the side of the socket
to lock it in place.
5. Locate the power connectors for cooling fans J1 and J4. Connect the cable from
the processor cooling fan to either J1 or J4.

Install the Memory Modules

For this mainboard, you must use 168-pin Dual In-line Memory Modules (DIMMs)
which are installed with SDRAM (Synchronous Dynamic Random Access Memory)
(SDRAM). This mainboard supports 3.3 volt DRAMs. This board can operate with a
30, 33 (Default) MHz system bus.
You can install 1 or 2 modules. If you only install one memory module, install it in
DIMM socket 1, and if you install two modules, install them in DIMM sockets 1 and 2.
Each module can have a maximum capacity of 128 MB, so you can install a maximum
of 256 MB using two modules.
1. The SDRAM sockets are keyed with notches and the DIMMs are keyed with cut-
outs so that they can only be installed correctly. Check that the cut-outs on the
DIMM edge connector matches the notches in the SDRAM socket.
2. Push the latches on each side of the SDRAM socket down.
3. Install the edge connector of the DIMM into the socket and press it carefully but
firmly down so that it seats correctly. The latches at either side of the socket will
