When my friend was trying to install ATI MCE for Microsoft Media Center 2005, it asked for a Hyper-Threading processor. Is this O/S only compatible with a Intel HT cpu? I do know there are hacks to get around non-HT CPU's, but wondering why ATI would work with Intel only on this O/S? Does anyone also know if older ATI All-In-Wonder Radeons (pre-9200) work? Such as the very first ATI All-In-Wonder Radeon 7000?
