CPU Upgrade/Reinstallation

To ensure that the system can enter BIOS Setup after changing the processor, the system starts 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). Then it automatically takes you to the Advanced menu with a popup menu of all the possible CPU internal frequencies.

For processors with locked frequency multiplier

60
