I'm looking for the jumper settings, the P2B manual has the "CPU Core (BUS)
Frequency Multiple" & "CPU External Clock (BUS) Frequency Selection" Jumpers
shown, but I'm not sure which of the following specs pertains to these
jumpers?

Intel specs for my PII/400:
CPUID String 0653
Package Type S.E.C.C.2
Core Voltage 2.0V
Bus Speed 100 MHz
Thermal Guideline 24.3W
Core Stepping dB1
Thermal Spec 90°C
L2 Cache Size 512K
Manufacturing Technology 0.25 micron
L2 Cache Speed 200 MHz
Bus/Core Ratio 6.0

Thank you in advance for any help!

Set the "CPU External Clock (BUS) Frequency Selection" jumpers to 100Mhz
to match your processor's bus speed. The settings for "CPU Core (BUS)
Frequency Multiple" don't matter because the processor will ignore them
anyway - the "Bus/Core ratio" is locked at 4.0x on the processor.

BTW, from the information you provided, I determined your processor
sSpec is SL3D5 - and yes, Intel's site does say the Bus/Core ratio is
6.0, but that's an error.
