Flashing your BIOS with the wrong BIOS file Most BIOS updates come as a zipped file containing the binary code file, the flash utility, and sometimes a README file.
Flashing the erasable memory of your BIOS with the wrong code is almost certain to cause failure the next time you try to boot. Many motherboard model names are similar within a single manufacturer.
As a rule of thumb if your computer is operating normally, leave it alone.
If you are unsure if a BIOS update will fix a problem that you are having with your PC, you can ask for more information from the manufacturer.
You might be able to get the information by entering the serial number of the PC on a Web site, but when it comes to flashing your BIOS you need to be 100 percent accurate and the information on the Web site could be incorrect.

I have a Dell XPS-M1530, trying to update from BIOS A08 to A9 (1530_A09.exe) or A12 (1530_A12.exe). My tech friend says he cannot understand why the Windows 7 upgrade program is asking to update the BIOS before it will load. I can download the BIOS file from Dell, but when I try to execute I get the following error: "An unexpected error occurred while trying to execute the flash application. Application error return 0x00000406" I reboot and no help.
