CPU Frequency [XXX] (value is auto-detected)
Indicates the frequency sent by the clock generator to the system bus and
PCI bus. The bus frequency (external frequency) multiplied by the bus
multiple equals the CPU speed. The value of this item is auto-detected by
BIOS. The values range from 100 to 400. Refer to the following table for
the correct Front Side Bus and CPU External Frequency settings. Use the
<+> and <-> keys to adjust the value.
Selecting a very high CPU frequency may cause the system to become
unstable! If this happens, revert to the default setting.
