Asus P4B - what fsb:pci ratios available?

A friend of mine has this board, but he doesn't know much about OCing or anything. Anyway I've been looking through the manual online and at some reviews, and can't seem to find if it has a 4:1 fsb: pci ratio or not, or if it's fixed. Does anyone know what ratios it has?

Thanks Acko. That thread is about the P4B533, but I'm sure that somewhere in those forums there is an answer about the regular P4B, so I will take a look.
