I tried using W7_DRVPREP made by razormoon to prep the latest catalyst driver 10.8 so I can inject it to my wim file using dism but to no avail, but the previous version of the catalyst driver v. 10.7 works. I also tried using the expand command w/ no luck. Can anybody give me pointers on how to inject the latest driver from amd v. 10.8 on win7 x64 using dism? Thanks...
