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

Systems and methods are provided that may be implemented to deliver firmware for pre-boot updates of targeted information handling system device/devices using custom update capsules (e.g., such as custom unified extensible firmware interface 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/drivers 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.
