2)CPU External Frequency Selection (DIP_SW Switches 1–4)

This option tells the clock generator what frequency to send to the CPU, DRAM, and the PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock). The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal frequency (the advertised CPU speed).

Frequency Selection

WARNING! Set the CPU frequency only to the recommended settings. Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable. Overclocking the processor is not recommended. It may result in a slower speed.

3)Manual CPU Ratio Settings (DSW Switches 5-10)

Set DSW switches (5-10) to use the clock multiplier to coordinate the ratio of bus speeds with CPU settings. Set the DSW switches according to the internal speed of your processor and the bus frequency (133/100MHz).

IMPORTANT:
1. To use this feature, JEN must	be set to Jumper Mode, [1-2].
(See 1, JumperFree™ Mode (JEN)	in 3, HARDWARE SETUP.)

2.When JumperFree mode is enabled, use BIOS setup in place of these switches. (Set Operating Frequency Setting to User Define under 4.4 Advanced Menu

in BIOS Setup so you can set the CPU Frequency.)
