Coprocessor driver

?

What?

Do you even know what a coprocessor is?

Windows 7 needs a 1Ghz x86 CPU (though you can use less I wouldn't advise it) and none of those have separate coprocessors. The last x86 CPU I know of with a co-processor was the 486SX which could have a separate FPU coprocessor installed thus letting it preform like the 486DX which did have a working FPU.
