Updating dell d620 bios

For example, MSI “strongly recommends” using their BIOS-based menu option instead of their Windows-based utility in the README file of the sample BIOS update we downloaded.

Flashing your BIOS from within Windows can result in more problems.

It’s better to be safe than sorry, so we recommend using a BIOS-based flashing tool or booting to a minimal DOS environment to flash your BIOS.

That’s it—after you run the BIOS-flashing utility, reboot your computer and the new BIOS or UEFI firmware version loads.

Some manufacturers provide Windows-based flashing tools, which you run on the Windows desktop to flash your BIOS and then reboot.

We don’t recommend using these, and even many manufacturers who provide these tools caution against using them.

In the minimal DOS environment that appears after the reboot, you run the appropriate command—often something like BIOS3245.bin—and the tool flashes the new version of the BIOS onto the firmware.This will render your computer unbootable—it’ll be “bricked.” Your computer’s BIOS version is displayed in the BIOS setup menu itself, but you don’t have to reboot to check this version number.There are several ways to see your BIOS version from within Windows, and they work the same on PCs with a traditional BIOS or a newer UEFI firmware.If there’s a problem with the new BIOS version, you may be able to downgrade it by downloading an older version from the manufacturer’s website and repeating the flashing process.Error: An unexpected error occurred while running the Flash application.
