e Select FlashBIOS Updates for the download category.
f Click Go.
3 Follow the instructions on the screen to download the BIOS update
utility.
NOTE: For some Dell systems, you are given a choice to create a diskette
containing the BIOS update files or to download a file you can use from
the hard drive. Select the choice to use the file that requires no
installation mechanism, or application. This allows you to download a file
that you can use from the hard drive.
4 Go to an MS-DOS prompt.
5 Change to the drive and file path where you downloaded the utility.
6 Type the command
xxxxx -writehdrfile
(where xxxxx is the name
of the BIOS update executable file on the diskette) and press
<Enter>.
This generates a file with an .hdr extension, and a message appears
indicating that the .hdr file has been written.
7 Copy the .hdr file to a blank, formatted diskette.
NOTE: This diskette does not have to be bootable. All operations for the
recovery utility are performed by the BIOS, and no boot files are required.
8 Insert the diskette into the diskette drive of the malfunctioning
computer. Then turn the computer on.
The computer automatically regenerates the BIOS from the diskette.
9 Remove the diskette from the diskette drive so that the computer does
not boot from the diskette the next time you start the computer.
