Upgrading the CPU
This system board supports Pentium III and Celeron processors and
future Intel processors. Both connects to a 370-pin socket form factor
instead of the slot connector form factor.
Note: Observe the ESD precautions when installing or removing
a system component. See section “Installation precautions” on
page 39.
Follow these steps to upgrade your CPU:
1 Remove the cover as shown on page 41.
2 Disconnect the 3-pin and 2-pin fan/heatsink cables from the system
board.
3 Unhook one side of the fan/heatsink metal bracket and gently lift
it before removing the other side.
4 Gently push the socket lever down to release the lever and then
pull it up to remove the CPU.
5 Insert the new CPU. Make sure that pin 1 (indicated by a notched
corner) of the CPU connects to hole 1 of the socket.
Push down the socket lever to lock the new CPU into the socket.
