BIOS firmware update, commonly abbreviated as BIOS firmware or simply BIOS flash, is the process of installing a newer version of the Basic Input/Output System onto a computer's motherboard. The BIOS is firmware that initializes hardware during the boot sequence and provides runtime services for operating systems and applications. Over time, motherboard manufacturers release firmware updates to add support for new processors, fix bugs, improve stability, or address security vulnerabilities such as the Spectre and Meltdown family of exploits.

Typical update procedures involve downloading an image from the vendor’s website, creating a bootable USB drive or using a proprietary utility, then restarting the system into a dedicated firmware environment. Some modern firmware images are signed, requiring the system to verify authenticity before installing to prevent unauthorized modifications. Users are advised to back up critical data and, when possible, power the motherboard with an uninterruptible supply to avoid corruption during the flashing process.

Certain updates can unlock previously disabled features; for example, enabling support for newer memory types or expanding overclocking capability. However, unlocking hardware in this way may void warranties or violate manufacturer terms. Consequently, many organizations deploy firmware update policies that balance benefit with compliance, employing tools that automatically check for out‑of‑date firmware across corporate assets. The careful management of BIOS firmware updates is essential for maintaining system security, compatibility, and performance.
