Programming information for nForce2 chipset?

Hello,

I'm searching for technical programming information for
my 8RDA+. Especially for the built-in PLL of the chipset.

I'm trying to program a software tool to set the Voltages
and FSB on my 8RDA+, currently only voltage setting is
working (http://www.hasw.net/8rdavcore) and I'm stuck on
the PLL programming. Because NVidia do not want to support
somebody with programming information I'm now searching
for other people which are "researching" in the same direction.

Because disassembling of the Bios is "illegal" (but the
POST Code output is maybe a good reference point to search
for the PLL settings code , I have not much options...

Thanks,
Sebastian
