III. H/W SETUP Motherboard Settings III. HARDWARE SETUP 4. CPU External Frequency Selection (FS0, FS1, FS2, FS3) This option tells the clock generator what frequency to send to the CPU, DRAM, and 440ZX 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). 123 FS3 123 123 123 123 FS2 FS1 FS0 CPU 66.8MHz 75.0MHz 83.30MHz 100.30MHz 103.00MHz PCI 33.4MHz 37.5MHz 41.65MHz 33.43MHz 34.33MHz 123 FS3 123 123 123 123 FS2 FS1 P2-99B R FS0 CPU 105.0MHz 110.00MHz 112.00MHz 115.00MHz 120.0MHz PCI 35.0MHz 36.67MHz 37.33MHz 38.33MHz 40.0MHz 123 123 123 123 123 FS3 FS2 P2-99B CPU FS1 External Frequency Selection FS0 CPU124.0MHz 133.0MHz 133.00MHz 140.0MHz 150.0MHz PCI 31.0MHz 33.3MHz 44.33MHz 35.0MHz 37.5MHz 5. CPU Core:External 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 conjunction with the CPU External Frequency.
