CPU Upgrade/Reinstallation

To ensure that your system can enter BIOS setup after the processor has been changed or reinstalled, your system will start up running at a bus speed of 66MHz and a fail-safe CPU internal frequency (4x66MHz for the Intel Coppermine processor or 2x66MHz for non-Coppermine processors). It will then automatically take you to the Advanced menu with a popup menu of all the officially possible CPU internal frequencies.

For processors with locked frequency multiplier
