Jumper Settings

1. CPU Bus Frequency (FS0, FS1, FS2)
This option tells the clock generator what frequency to send to the CPU. 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).
2. CPU Core:BUS Frequency Multiple (CF1, CF2, CF3, CF4)
This option sets the frequency ratio between the Internal frequency of the CPU
and the CPU's External frequency. These must be set in conjunction with the
CPU Bus Frequency.
WARNING! Frequencies above 66Mhz exceed the specifications for the onboard
Intel Chipset and are not guaranteed to be stable.
Intel Pentium II Processor in a SEC Cartridge
(233-400MHz 512KB/128KB/0KB L2 Cache)
Set the jumpers by the Internal speed of your processor as follows:
CPU Model Freq.
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.
