I decided to risk trying them out as I wasn't getting a reply, I didn't want to damage my board in anyway. But yes you're right the ROM for my P5Q deluxe didn't seem to add any settings in bios. Judging by King T's settings he had extra settings in his from whichever bios he used, hence why I kindly asked him before if he could verify or upload his ROM, if it was for the P5Q deluxe.
RGWoods ROM didnt flash to my board. EZ Flash reported that it was the incorrect size, so I had to make do with Ket's.
