i've been using this method for a while already... it is a super way to intergrade driver... more and more drivers keep coming and keep bigger... this method helps a lot... just need to ask a simple question to any expert.... of the oem copy... how will it works if i have 2 folder drivers.... with same name abc.inf in each folder... and they are not the same driver..... will they also work? about raid... i already intergrate... nvidia, intel, highpoint, Jmicron, SiImage XXXX, SIS raid, Via raid.. with this method and all works like charm... =)
