The BIOS on your computer is essential for it to function, yet it remains behind the scenes. In this article, you will discover what this hidden software does, and the reasons why you may need to access it someday.
A Good Article but OEM Non-Builder Machines do not have very many configurable settings in their Bios thus leaving folks with Pre-Built Machines "up the preverbal creek without a paddle".
As a side note, I haven't found any instructions on How to Upgrade Flash a MS Surface Pro 2 or any other new mini machines either.
Im sorry, but you said to experiment with your BIOS:
Experiment for yourself so you can utilize BIOS in the future when you need to troubleshoot a problem or configure an advanced system setting.
This is an absolutely a horrible suggestion. Never change BIOS settings unless you have a very good idea what will happen, as well as know how to recover from making a change that breaks your system.
Wait... what? Long as you don't mess with overclock settings that your processor hasn't been meant for, or don't flash wrong BIOSes, nothing can happen you can't reverse (far as I know).
As to remarks by ACF and NSDCars5: More like this - yes, whatever you do is reversable, but also yes, you can really mess things up. So, if you don't know what your doing (like moi), start by doing one thing at a time, keeping track of what you did and what effect that change had. Then you will not get in trouble you have no idea how to fix.
Disclaimer: this is a non expert opinion, subject to revision, but I think (for the moment, at least) good procedure.
Well, it's the way I learned my way around BIOS, and no harm ever came of it. As the article says, just be careful that, after messing around, you don't "exit and save changes". Just "discard changes and exit" - I believe that's the wording that most BIOS use.
How else are you supposed to practice using BIOS other than to use it? I definitely agree that you don't want to save any changes unless you're aware what that change does and how to recover from it, as you said.
