If you want to know if its compatible, go here.

Intel has a little tool on their website that lets you know what motherboard is compatible with each processor type. its has thousands of mbs listed so it looks pretty helpful.

I found my abit bx6 2 on it. intel says my mb will work with any 100mhz fsb intel p3. kind of nice to know when abit never responded to my email.

I also found it interesting to know intel released a p3 1.1 ghz 100 fsb cDo chip too.
