P2B-D Frequency Multiple Jumpers for > 600Mhz

Setting up an Asus P2B-D rev. 1.06 which can handle up to 1 Ghz Pentium
III's. However the manual only shows the jumper settings for the "CPU
Core:BUS Frequency Multiple" up to 600Mhz. Where can I find an updated
settings table?

Ever heard about multiplier lock?

I take it the Jumper settings for Bus Speed and Multipler then on the
motherboard are irrelevant. Doesn't matter what I set them at?

Would the P2B-D be able to support 100mhz and 133mhz Pentium III 1 GHz
processors. Or do I have to use 100mhz processors to maximize the rev. 1.06
board?

The processor will ignore the multiplier jumpers - you can remove them
if you like. To make up for that :-) the motherboard will ignore the
processor's Bus Speed request and use the jumper settings - so the FSB
jumpers need to be set correctly.

That depends on the PCB revision level. Rev 1.06 D02 and earlier support
a maximum FSB of 112Mhz. Rev 1.06 D03 supports 133Mhz, but overclocks
the PCI and AGP buses by 33%. Many AGP video cards will tolerate the AGP
overclock, especially those with nVidia chipsets, but the PCI overclock
causes problems with many devices. Fortunately it can be fixed:

Rev 1.06 D03 boards can be recognised by the yellow sticker near the AGP
slot, as in the picture at the bottom of this page:
