G4/533 motherboard

[bmcbean49]

I have a G4/533mhz single processor. It says that if my motherboard is a "revision 7" , I should be able to upgrade to a dual processor. How can I tell if my motherboard is "revision 7".

Usually revision numbers are silk screened onto the motherboard. I'd try reading all the text on it, including the bottom.
