This motherboard supports an Intel Pentium II processor using a Single Edge Contact
(SEC) slot. Make sure that you have the following items (which should be included in the
package) before doing any installation: (1) 4 screws (2) 1 retention clip.
(1) There are 2 sets of small holes along Slot 1 of your
motherboard: two on the top and two on the bottom. Snap the
retention clip (2) right into those 2 sets of holes. If the retention
clip is installed incorrectly, you will not be able to insert the CPU
into the retention clip.
(2) Find the holes in each corner of the retention clip and insert
one of the four screws into each of these holes.
(3) Push the screws downward to secure the retention
clip.
(4) Flatten the two latches on the side of the CPU. Insert
the CPU into the retention clip. Lock the two latches to
secure the CPU.

The system bus speed can be set to 66.6MHz or 100MHz from the jumper (
JP6
). The
user can change the DIP SWITCH
(SW)
selection to set up the CPU speed for different
processors. The CPU speed must match with the frequency RATIO and Front Side Bus
(FSB) speed. It will cause system hanging up if the frequency RATIO and FSB Speed do
not match with the CPU.
