III. HARDWARE SETUP
2. CPU Bus Frequency Selector (FS0, FS1, FS2, FS3)
This option tells the clock generator what frequency to send to the CPU, DRAM,
and the AGPset. 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). NOTE: You may set the
memory speed independently from the CPU Bus Frequency. Depend-
ing on your memory type PC66 (66MHz) or PC100 (100MHz), select
the appropriate "RAM" speed along with the appropriate "CPU" speed.

3. CPU Core: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. These must be set in conjunc-
tion with the CPU Bus Frequency.
MES-VM CPU Core:
Bus Frequency Multiple
WARNING!
Frequencies above 100MHz exceed the specifications for the on-
board chipset and are not guaranteed to be stable. PCI frequencies above 33MHz
exceed the specifications for PCI cards and are not guaranteed to be stable.
Set the jumpers by the Internal speed of your processor as follows:
