Notes for JumperFree Mode
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 speeds.
System Hangup
If your system crashes or hangs due to improper frequency settings, power
OFF your system and restart. The system will start up in safe mode running
at a bus speed of 66MHz and enter BIOS setup.
