overclocking a shelf system

I read the tutorial on overclocking and what to give it a try. My friend always says that to overclock you just adjust jumpers on the board? Whatever. From what I gather it's all about settings in the bios. I don't have any of these settings in my bios so is there nothing I can do. My system is an off the shelf system. An HP. It's a AMD3000+, 512 pc2700, via chipset. Don't know the board type yet. Please if there's anything that I can do please help. I'm not looking to do anything drastic, I just want to start learning. Thank you very much.

 

your bios has none of the settings? did u try do get it updated maybe?
