P4 motherboard,
has 2 DDR RAM Inputs
3pci slot
1 agp input
says REV 1.2 IBM on it
can anyone help me out or at least tell me how i know wot model it is?

 

If you look closely you'll see a row of connectors on the mobo. It should be written beside them what each one does, you may need a magnifying glass to read them. Also if you go to the manufacturers site you may find out some info.
