I'm replacing my kt7a mobo with the iwill kk266 free of charge. I read on the iwill website that it says to use the 4in1 v4.23. Is this true? How do i know which mobos are via based chipsets (which require the 4in1 drivers)? Do all amd mobos require the 4in1 drivers? I'm getting confused as to which drivers need to be downloaded for mobos. I want to make sure I install the proper drivers. I already put the latest bios on disk for when i get the mobo. It's 515, if I downloaded the proper bios update. Any websites that give particular info on this mobo please post.
