I received a request to vote on the best answer on of all days ELECTION day. I doubt that coincidence but as I tried to respond to that it was a NO REPLY forum address. I did reply above to the SINGLE response I got to my inquiry and informed those interested of the situation. I got ONE response and it was CLOSE to what I had, but not exactly. I have an ATI Radeon XP400 series chip set and have not found ANY information regarding this board that tells me it's parameters. The only response I got was close (ATI Radeon XP 200) and I am able to presume that at least I can add RAM to a level of 2 Gig from that. It doesn't appear there are any upgrades or BIOS flashes available for this board to improve it's performance . While I do appreciate that much, it is difficult to choose THE BEST answer when you've only got ONE isn't it? It is by default the best because it is singular in destination, so I did not feel I needed to single that out. IF you desire I do so and close the thread I will comply and allow it to be considered resolved. I await your reply.
