I formatted my C:Windows partition and did a clean Install of my custom Windows XP pro with latest hotfixes. However, all the other drivers install fine except when I try installing the audio drivers for the RealTek HD Audio. It says in the installation process that the Windows System Bus drivers are missing during installation. I've gone almost everywhere on the internet looking for a solution. I got the windows UAA hotfixes,latest REALTEK HD drivers,Intel HD audio drivers,etc. but none of that seems to work. For right now i'm on the standard windows xp home that came with my recovery partition. I would really like to make a clean install of XP pro on my s460 and get everything working the way it should be without having to rely on the recovery partition. Can someone please help me? I assume that since this section of the forum is dedicated to sony notebooks that I may be able to recieve help from someone who has experienced this very same issue.
