post (subpost #15), I'm giving you a "key" to access your BIOS easely, no matter what type of a motherboard you have.
It's useful to change the boot order through your BIOS to be CD-ROM first, so that you could install Windows XP, Windows 7, Linux 9.10, Linux Mint 8... whatever you want to.
Changing BIOS / setting it to (some specific) wrong parameters CAN "KILL" YOUR HARDWARE!! So, be warned, and don't "play around" with your BIOS... BIOS is not the thing, to play within it... unless you're a system admin, and you know, what you're doin'.
==> If you want to "stress up" your computer, but overclocking it (still, can't see a reason, why people are doing this, unless it's just for their fun) - you always have some tools, that can be ran through OS's environment.
