Flash BIOS Update in PE environment

Posted on 2005-04-13
Last Modified: 2012-06-27
Im using BartPE, trying to figure out a way to flash the bios. Currently I'm using the Dell Optiplex GX280..

I downloaded the GX280A04.EXE from Dell.

When I try to run this inside PE, I get the error..

Flash Access Denied
Please make sure you are logged in as an Administrator then try re-starting the application.

Has anyone tried this before?

Anyone? I'll set the question at 20 points for now. If I can get a working answer then I will increase. Im not sure how difficult this is. Thanks everyone!

    I understand and know how to update the bios through DOS, but my confusion comes straight from the comments for this particular BIOS update,


    This file format consists of a BIOS executable file. <b>The Universal (Windows/MS DOS) format can be used to install from Windows XP, Windows 2000, NT, Windows 9X, Windows ME or a MS DOS environment</b>.


    Does that not say that this update can be run in each of the above environments, not just DOS? Or am I mis-understanding?

    The BIOS flash, even if started from a Windows GUI, is executed in DOS, the OS is shut down. Please explain your objectives in trying to use BartPE (Bootable CD BIOS Flash?), etc. Many DOS tools are incompatible with BartPE, this may be where the problem lies.
