HP laptop dv 6705ca coprocessor drivers for windows 8

I installed windows 8 Pro 64bit and have found the basic drivers except I am still getting the coprocessor without a driver.

I have the AMD Athlon 64 X2 Dual Core Processor TK-57   1.9Ghz.

I have tried a couple AMD drivers.  No sucess.

Any help would be appreciated.

Thanks
