I have a K7SEM motherboard with a Duron 850 processor. I would like to upgrade to an Athlon XP. My motherboard's website has a CPU Support Table that says I can go up to an Athlon XP 2100+ as long as I upgrade the BIOS. The only concern I have is that the motherboard manual says it can support FSB speeds up to 100/133 Mhz. The Athlon XP 2100+ has a 200Mhz FSB. Does that mean the BIOS upgrade will allow it to run a processor with a FSB over the 100/133????? Is the Athlon XP going to be compatible?
