8) CPU External Frequency Setting (SW1-1, SW1-2, SW1-3, SW1-4)
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. 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 PC66 (66MHz) or PC100 (100MHz), select the appropriate “RAM”
speed along with the appropriate “CPU” speed.
9) Memory Transfer Mode Setting (SW1–5)
You can set the memory clock frequency to be in synchronous or asynchronous
mode with respect to the CPU external frequency.
