Better visit the motherboard manufacturer's website or find other documentation on exactly what processors that motherboard will support.

i did and the processor i have is supposedly supported, but......

I have a P4 Northwood 2.8 and the bios automatically ses it as a 1.866 ( 14x133) I can set it 166/33 and get 2.2 out of it but still the processor should be 2.8. Its a P4SGX-MX ASUS. Windows correctly sees it as a 2.8 running low, either a 1.8 or a 2.2 depending on what i have it set at ( funny thing is that 14x166 is 2324 and not a rounded 2.2 ) What the heck is going on here? I have the most recent BIOS. I was wondering if the FSB could be a factor here.

I honestly don't know.  I gather 166/33 is the highest setting in the BIOS.  Is that right?  And, you have no control over that multiplier.  Is that right?
