Hi,
I have just had to build an xp system that is an E system Ei 204. AT first the only thing relating to the system I could find was this thread so I've picked it up for anyone trying to re-install the system in the future. The Motherboard on the one I've just done is made by FOXCONN. If you look in the motherboard by the logo there is a long model number (P4M800P7MB-RS2H). After trawling their website their support doesn’t work. IF you go to post a tech question you get to a second tech site that has all the drivers. foxconnchannel.com/support. Search by product model:Motherboards > Socket 755 > P4M800P7MB-RS2H. All the drivers you need. On the system I just did the USB controller was disabled in the BIOS which threw me for a while so if you get no USB ports after chipset patch look in the BIOS. Hope this helps any future people.
Cheers,
Rob
