Basic BIOS Tweaking Guide

Basic BIOS Tweaking Guide

By: TweakTown Staff | Guides | Posted: Jul 12, 2001 4:00 am



Nothing much else you can do on a rainy day! I have created a Basic BIOS Tweaking article which will run through certain settings and describe what they do, in 'people language'


When your computer starts up either hold the DEL key or when you see a message saying change setting or something similar to that press DEL. No we are in the bios, you should see a blue screen with a few menu options. These setting were designed for a ABIT Bios but I'm sure you'll find the below options in newer motherboards! The options are in order as they appear in my bios, but you may have to search around for them, they also may have a slightly different name to below, good luck!
