3. HARDWARE SETUP
8) CPU External Frequency Setting (DSW–SW2-6)
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. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU's
Internal frequency (the advertised CPU speed). NOTE: You may set the memory
speed independently from the CPU External Frequency. Depending on your
memory type, select the appropriate "SDRAM" speed along with the appropri-
ate "CPU" speed.
IMPORTANT: When JumperFree mode is enabled, use BIOS setup in place of
these switches (see CPU Speed in 4.4 Advanced Menu). Only selected switches
are illustrated, see the next page for a complete frequency listing.
NOTE: For JumperFree mode, DIP switches 2-6 (DSW) must be set to OFF.

WARNING!
CPU frequencies other than 66MHz, 100MHz, and 133MHz are
not guaranteed to be stable. Premature wearing of the processor may result when
overclocking. Be sure that the DIMM you use can handle the specified SDRAM
MHz or else bootup will not be possible.
