This computer is a Dell XPS T series computer, with a PIII 550 mhz processor (i believe its a slot 1 processor), but im having a hard time trying to figure out what is the motherboard model. I called Dell and all they could tell me whats that it is using the 440BX AGPset. Also when restarting the computer, no Motherboard model comes up in the loading screen. can anyone give me some clues to find out what motherboard model i have?
