BIOS Recovery Utility
If your computer loses power and beeps constantly but does not boot when
power is restored, the basic input/output system (BIOS) is probably
corrupted. To restore the BIOS, perform the following steps:
1
Disconnect the computer from its power source.
2
Go to another working computer, and download the BIOS flash
executable utility for the computer from the
File Library
located on
Dell's
support.dell.com
website.
3
On the working computer, go to an MS-DOS prompt and type the
command
xxxxx
- writehdrfile
(where
xxxxx
is the name of the
BIOS flash executable utility you downloaded).
Running this utility generates a file with a
.hdr
extension.
4
Copy the
.hdr
file to a floppy.
5
Insert the floppy into the floppy drive of the corrupted computer and
turn it on.
The computer automatically flashes the BIOS from the floppy.
6
When the computer begins to restart and the Dell logo screen appears,
remove the floppy from the floppy drive so that the computer does not
boot from the floppy again.
