    Everything I'm reading on the web about that is bad. Is your laptop booting up normally and everything, or is this before the OS boots?

    I also get it as well when I'm booting and it's at the BIOS boot part.

    I believe it just means that a copy of the Video BIOS is stored in system RAM so that it can be accessed faster; not that I know when exactly it needs to be accessed, and I might be wrong.

    Lol, we don't have much choice, it's enabled by default and no way to change it in the BIOS. We ALL have both our system BIOS and video BIOS shadowed. During boot up you can pause the screen at just the right time you can catch it where it says it. Many times desktop BIOS's allow you to control it, but most modern laptops do not give you any control over it.

    thanx for the link rep+

    I am sure there should be a way to disable it.

    now thats the Video Bios (we know that best if its disabled unless you play doom on dos, Lol)

    what about the normal BIOS? is shadowing it worth doing?

    and if anyone wants to see where it says "Video Bios SHadowed" put your batteries one, and run your laptop without plugging the AC, you will see that the screen will stop and says "its better for you to plug in the AC bla bla for best performance " then you can see it.

    its important to note that before i installed the latest Dell VBIOS i didnt see this message (or did i?)

    edit: dajohu already put a screenshot of the message

    Shadowing is a old technique and if I remember correctly should not hinder any performance at all. I remember testing it quite a bit when it was first introduced and not noticing any impact whatsoever.

    I haven't read the article yet but I usually turn any type of shadowing off now. We've gone passed having to do that I think.

    any idea on how to do it in our machines? R2? (i.e. disabling shadowing)

    I have checked the advanced settings in the BIOS and i didnt find anything related to recaching / shadowing / etc ? let alone the VBIOS shadowing
