Systems And Methods Of Device Firmware Delivery For Pre-Boot Updates

摘要

Systems and methods are provided that may be implemented to deliver firmware for pre-boot updates of targeted information handling system device/s using custom update capsules (e.g., such as custom UEFI capsules) and a separately-stored firmware update package that is remotely or locally stored. The custom update capsules may contain instruction payload information that may be used to determine location and desired components of the separately-stored firmware update package, and that also may be used to determine whether existing driver/s are to be retained in a firmware module in system memory or to be unloaded and replaced with a new (e.g., upgraded or downgraded) driver version in a firmware module in system memory as part of the firmware update.

主权项

1. A method of delivering firmware for pre-boot updates to an information handling system, comprising using at least one processing device of the information handling system to perform the following steps in an out-of-band manner prior to booting the information handling system:
retrieving a custom update capsule from a source external to the information handling system; reading instruction payload information contained in the custom update capsule to determine a specified location of a given firmware update package that is remotely or locally stored, the given firmware update package being separate from the custom update capsule and including one or more firmware images; and retrieving the given firmware update package from the specified location determined from the the specified firmware update package.
