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 PIA-662Pro.
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
FSB speed (JFSB1, JFSB2)

1-2 2-3 100 MHz
1-2 1-2 133 MHz
