hi, i got the exact same problem as you. aka i also havea 2500+ and a agp 9800 pro. im trying to figure outa solution rihgt now. so far i;ve posted a ticket on the ATI site. And recently i scoured a forum and a guy said he got his 9800 to work by manually installing the .Inf file form the latest XP driver package. now i dont know how to do that. i would give it a shot if i knew though. any help from anyone would be much appreciated.
