CPU and CMOS Jumper Settings
FSB/Core Ration (Auto-detect)
The FSB/Core ratio has been prefixed inside the Pentium-II/III and Celeron
CPUs by Intel. The prefixed ratio is auto-detected by the 3303955.
CPU Frequency is ratio multiplied by FSB speed. The FSB value can be set by
jumper to 66, 100 or 133 depending on the speed of the Pentium-III / Celeron.
Maximum frequency supported is 8 x 133 = 1.13 GHz
