How to overclock a Soyo 7VCA-2

I have a Soyo 7VCA-2 motherboard with a 750 Mhz processor. I'd like to try
to overclock it, but I the changes I've been randomly making to the bios do
nothing (other than lock up the PC). Can anyone give me an idiots guide
(tell me how) to overclocking this motherboard? What changes do I need to
make to the bios to get this puppy up to at least 800Mhz?

Thanks,

Larry
