CPU Internal Frequency
In JumperFree™ Mode, this field allows you to select the internal frequency of your
CPU. Select [Manual] if you want to make changes to the subsequent 2 fields. Note
that selecting a frequency higher than what the CPU manufacturer recommends
may cause the system to hang or crash.
System/PCI Frequency (MHz) (when CPU Speed is set to
[Manual])
This feature tells the clock generator what frequency to send to the system bus and
PCI bus. The bus frequency (external frequency) multiplied by the bus multiple
equals the CPU Speed (for unlocked CPU only).
System/SDRAM Frequency Ratio [Auto]
This field determines whether the memory clock frequency is set to be in synchronous
or asynchronous mode with respect to the system frequency. The options that appear
in the popup menu vary according to the System/PCI Frequency (MHz).

These fields allow you to choose from the default of [Enabled] or choose [Disabled] to
turn on or off the CPU Level 1 and Level 2 built-in cache. Configuration options:
[Disabled] [Enabled]
CPU Level 2 Cache ECC Check [Disabled]
