2-3 Auto Detect CPU Voltage

Note: You do not need to set any jumpers since this
motherboard auto detects the Pentium® II processor
voltage.

This motherboard is designed to automatically detect the CPU
voltage. Therefore, it is not necessary to set any jumpers on the
motherboard.

The 133/200MHz setting is used as default so whenever the BIOS
settings are erased or reset the board will be able to boot up.
However, there is no Pentium® II processor of that frequency.

If the CPU frequency was set too high and the motherboard refuses
to start up, you can always load the default values by pressing the
[Ins] key during boot up.
