What process is performed during upgrades, security fixes, or feature improvements related to BIOS/UEFI?

Flashing is the process of updating the firmware of the BIOS or UEFI. This process involves writing new data to the firmware chip, which helps address various needs such as upgrades, security vulnerabilities, and feature enhancements. By upgrading the BIOS/UEFI through flashing, users can improve system stability, add support for new hardware, or enhance overall performance.

In contrast, boot order configuration refers to the arrangement of devices from which the system will try to boot, which is not directly related to the process of firmware updates. Secure Boot activation entails enabling a feature that helps ensure that only trusted software loads during the startup process, but it does not encompass the act of updating the firmware itself. A pre-operating system environment check occurs during the boot process but does not specifically mean altering the firmware; instead, it verifies that the boot conditions are set correctly for the operating system to start.
