It'll save you hours of fruitlessly trying to find a software problem that doesn't exist. Don't ask me how I know this unless you want a rant... ;) > > Mark Thankfully not. It's an ALi (or ULi - same company I think) chipset. Although it could still be the problem. I'll probably tinker some more tonight. Thanks for the idea though! Chris.
