Hi Tony, Great site. It has saved me an enormous amount of time. I just completed my 1st build, GA-P55A-UD3, i5 750 w/ ATI HD 4650. I just posted in DSDT about the hack I performed for the ATI graphics card I have. I used the provided hack in DSDTSE app, #13. It works great, but know I'm going to try your hack that you provided on a separate HDD. Again thank you very much. Styro
