This device firmware can be updated using a device driver package using the same mechanism as system firmware. Device firmware updatesįor the purposes of updating device firmware, the device firmware can be assigned to one of these two categories: The driver package will contain an INF file and a binary file containing the system or device firmware image. After the firmware update package is on the end-user's system, Windows will use the UEFI UpdateCapsule function to hand-off the firmware payload to the platform firmware for processing.ĭeploying the update as a driver package allows the firmware update process to align with many existing deployment and servicing tools, and ensures simple update package authoring for hardware vendors.Īlthough the firmware update is delivered as a driver package, it does not mean that the update is written as an actual driver. A firmware update package contains a binary file containing the system firmware image. Windows will use information provided by the platform to ensure that the update package only applies to appropriate systems. System firmware updates for UEFI-based systems will be deployed as device driver packages (INFs).
Such device firmware typically works together with a device driver, allowing the OS to expose the device to OS-level services and applications. System firmware is responsible for providing critical boot and runtime services to the system as a whole, and device firmware is associated with a particular device integrated into a system. There are two types of firmware that can be serviced via Windows: system firmware and device firmware. Overview of the UEFI firmware update platform
UEFI firmware update support in Windows 10Īll systems that run Windows 10 for desktop editions should implement UEFI firmware updates by following the UpdateCapsule-based update process described in this section of the documentation. Windows 10 for desktop editions (Home, Pro, Enterprise, and Education)
The UEFI firmware update platform is supported by the following operating system versions: The UEFI firmware update platform guidance is intended for SoC vendors and OEMs who are building hardware platforms that run Windows. This platform provides a consistent, reliable firmware update experience, and it improves the discoverability of important system firmware updates for end-users. Windows supports a platform for installing system and device firmware updates via driver packages that are processed by using the UEFI UpdateCapsule function.
