Unknown Registry Keys

[Aegis]

Anyone have any idea what these undocumented registry keys are for?

Uh... I bet the first one disables the FPU and has the CPU do math instead. (This was needed for some crappy Intel FPUs IIRC.)

That wouldn't make sense since the FPU is part of the CPU. BTW how do people find out what registry tweaks do in the first place?

The FPU may be built into the CPU but it is a separate circuit. In this case the OS would simply use standard x86 code to do floating-point math instead of having the FPU do it.
