4. CPU BUS Frequency Selection (FS0, FS1, FS2, FS3)

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

WARNING!

Frequencies above 100MHz exceed the specifications for the on-

board chipset and are not guaranteed to be stable.

WARNING!

PCI frequencies above 33MHz exceed the specifications for PCI

cards and are not guaranteed to be stable.

5. CPU to BUS Frequency Multiple (BF0, BF1, BF2, BF3)

This option sets the frequency multiple between the Internal frequency of the
CPU and the CPU’s External frequency. This must be set in conjunction with the
CPU BUS Frequency.
