Hi all, just a general note. My Dad's install of SP2 failed miserably. Even a scratch/reinstall failed miserably. Symptoms - freeze during boot. A safe-boot boot shows the infamous "mup.sys" as the last entry. Board - Asus P4P8 Deluxe. Same with my uncle. Identical board, identical problem. In both cases, flashing to the latest BIOS solved the problem. And why am I writing this posting? Because I'm currently pulling my hair out with a friend's Time Computers ( ) system. Same problem, but no BIOS to download. £1/min for technical support - I don't think so! Sigh....slipstreamed SP1 currently going on. I'll then apply all the hotfixes (via my SuS laptop), and then disable Automatic Updates. So....the moral? There's something seriously stuffed in SP2. BIOS updates seem to solve the problem, but if you cannot get a later BIOS, it's just tough! Jim
