Unable to Change the FSB of a Biostar M7NcG Pro (nForce2) any sugestions?

[Randog77]

I'm trying to change the FSB of my Biostar M7NCG Pro, and it doesent' change. I can change the Clock Multiplier (on an unmoddified 1.2 Ghz Athlon?), but everytime I change the FSB in the Bios, it does nothing, and keep the "default" of 100 Mhz (200Mhz double data rate). Anyone else have this problem? As I mentioned the CPU is an old Athlon 1.2, but I'm pretty sure it should have a FSB of 133, not 100. Thanks in advance.
