4. CPU Bus Frequency (FS0, FS1, FS2)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
440BX 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 fre-
quency (the advertised CPU speed).
5. 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 conjunction with
the CPU Bus Frequency.
P2B-D2 CPU Settings
WARNING! Frequencies above 100MHz exceed the specifications for the on-
board Intel Chipset and are not guaranteed to be stable.
Intel Pentium II Processor in an SEC cartridge (233-450MHz)
Set the jumpers by the Internal speed of your processor as follows:
CPU Model Freq.
Intel Pentium II 450MHz
Intel Pentium II 400MHz
Intel Pentium II 350MHz
Intel Pentium II 333MHz
Intel Pentium II 300MHz
Intel Pentium II 266MHz
Intel Pentium II 233MHz
NOTES: Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not needed for the Pentium II
processor because it sends a VID signal directly to the onboard power controller.
