Hello all, I'll try to make this quick. I've got a Dell XPS 400, 2.8GHz Pent. D, 4GB RAM, running Vista Home Premium 64-bit SP2. It has been a great PC all things considered. It came from Dell with XPMC on it. I'm trying to update my BIOS from revision A05 to A07. I downloaded the file, which is an .exe and it will not run. I tried running as admin but no dice. Any ideas as to why it won't let me flash the bios?

Board: Dell Inc. 0FJ030
Serial Number: ..CN7082163B107A.
Bus Clock: 800 megahertz
BIOS: Dell Inc. A04 04/19/2006

XP051A07.exe This is the file that Dell gave me for the revision. I dunno what the heck is going on, and I'd appreciate some assistance on the matter please. Thank you.Attached File  Untitled.jpg   27.03KB   18 downloads

You NEVER flash a motherboard BIOS while running windows!!!!!!!!!!!!!!!!!!!!!!!!

You were about to make your system permanently un-bootable.

The proceedure is done in DOS.

You make a bootable floppy disk.
Delete all files from the disk.
Add the flash utility to the disk.
Add the correct BIOS image to the disk.
Remember the BIOS files name.

Boot to the floppy disk.
once you get the A: prompt you type the name of the flash utility. (Example: aflash )
The utility will run and present options.
(MAKE SURE you choose save origional BIOS to disk and save it to the floppy.)
Once thats done go back to the flash main menu.
Choose update new BIOS image.
Then type the EXACT name of your NEW BIOS image file.
DO NOT TURN OFF THE POWER or RESTART machine until you are told to restart, not until then.
TO restart hit ALT-CTRL-DELETE
Upon restart hold the correct key to enter the BIOS setup (either f2 or delete) choose LOAD SETUP DEFAULTS.
Then F10 to save and exit.
Hope for the best that your operating system loads.

if you have a cd-rw or dvd burner, burn a bootable disk with just those two files. Problem doing it this way is you cant save your origional BIOS to a rom drive in DOS without burning software running.
In your BIOS setup go to BOOT options. make sure the drive you use is set to boot before the drive C: does.
if your lost as to what drive your dvd is in DOS. just try D:dir or E:dir
Run the flash program from there

But I suggest you do the following, which is BEST option.
If there is a Floppy port on your motherboard, I suggest you borrow a floppy drive to use/

It isn't usually recomended to update the BIOS unless the update will fix a specific problem you are having

I agree with Stang updating the bios if not absolutely needed if very foolish, it can if not done PERFECTLY leave you without your machine IE Bricked!

Both stang and phil are correct!
Flashing the BIOS ROM does involve irreverseable consequences!

Proceed with caution if you choose to flash the chip.

Also doing a search engine serach for flashing the BIOS rom, before doing so will give you more input both good and bad to give you a better idea of what's involved.

Good luck!

You NEVER flash a motherboard BIOS while running windows!!!!!!!!!!!!!!!!!!!!!!!!

This used to be true

Run the BIOS update utility from Windows environment


1. Double click the Icon on your desktop labeled XP051A07.EXE.
The Dell BIOS Flash window appears


2. Click the Continue button.
The message Pressing OK will close all applications, shut down Windows, Flash the BIOS, then reboot. appears.


3. Click the OK button.
The system will restart and the BIOS Flash will be completed.

From Dell's installation instructions
http://support.us.dell.com/support/downloa...p;fileid=192889

Some other boards have this capability also
This does not mean that the process should be taken lightly
Precautions should still be followed
