This system board has a Slot 1 for the Pentium II, which comes packages either in a single edge contact cartridge (SECC) or a single edge processor package (SEPP) for the Celeron processor. For either processor, the system board uses a universal retention mechanism (URM), which is preinstalled on the board. Follow these steps to install the fan on the side of the processor first, and then install the processor on the system board.
Unfold the URM arms. Flip both arms up until they look into the position
Examine the fan and processor to see how the fan braces line up with holes in the side of the SECC. Place the fan directly on the side of the SECC. The two should fit tightly together with absolutely no space between them.

After the fan and SECC are fitted together, place the SECC on a table and push the clamp on the fan down into place, to secure the fan to the SECC.

Insert the fan and SECC into the sporting arms. The SECC should fit snugly into Slot 1, similarly to the way an expansion card settles down into an expansion slot. The arms should snap into position when the SECC is fully seated. Be certain you have a good fit here.
DIAGRAM – INSERT THE FAN AND SECC INTO THE SUPPORTING ARMS
Lock the SECC into position by pulling the SECC locks outward until they lock into the supporting arm lock holes.
Connect the power cord coming from the fan to the power connection on the system board. Look for the power connection near Slot 1. If you have trouble locating it, see the system-board documentation.

Our system board has three DIMM sockets, and each socket can hold DIMMs that contain either 8, 16, 32, 64, 128, or 256 MB of memory. Therefore, the amount of memory installed on this board can range from a minimum of one DIMM with 8 MB to a maximum of three DIMMs each having 256 MB for a total of 768 MB. In our example, we are installing a single 64-MB SDRAM DIMM that is PC100-compliant, meaning that it is rated to work at the memory bus speed of 100MHz.
As shown below, insert the DIMM into DIMM Slot 1 (the DIMM slots are labeled 1, 2, and 3), following these directions:
Pull the supporting arms on the sides of the slot outward
Look on the DIMM edge connector for the notches, which will help orient the DIMM correctly over the slot
Insert the DIMM straight down into the slot
When the DIMM is fully inserted, the supporting arms should pop back into place.

Step 4: Verify that the System Board is Working by Performing a Memory Test
Before we get too far along in the details of the installation, do a quick verification that the critical components are working. To do this test, connect the video card and connect power to the system board, plug in the monitor, and turn on the PC and the monitor. You should get a good memory test (before the first error occurs, saying that BIOS cannot find a boot device). By getting a good memory test, you know that the BIOS, RAM, CPU, most of the system board, and video are all working. If anyone of these components fails, there is no point in continuing the installation until the problem is located or the part replaced.
