Updating your bios

In most cases you should update to the latest version of the firmware that is available from your manufacturer.

The release notes for each release will describe the bug fixes for each release and will help you decide if you need to update.

WARNING: Dell notebook computers must have the battery installed and also be running on A/C power prior to updating the BIOS.

The BIOS is low-level system software that should “just work” without getting in your way.To upgrade the firmware, follow the instructions provided by the PC manufacturer.Some versions of the MEBx have a FW Update Settings option that may prevent local updates in the field if PC was previously configured with this option.Computers are now coming with UEFI firmware instead of the traditional BIOS, but the same is true for UEFI – it’s low-level system software with a similar role.Unlike your operating system (which is stored on your hard drive), your computer’s BIOS is stored on a chip on your motherboard.
