TLDR
In this article, a firmware update package is sent at an information handling system, containing a transition basic input-output system (BIOS) and another payload containing a new BIOS.Abstract:
A method includes receiving a firmware update package at an information handling system. The update package includes a payload containing a transition basic input-output system (BIOS) and another payload containing a new BIOS. The new BIOS is stored at an Extensible Firmware Interface system partition (ESP). A firmware image at a BIOS flash device at the information handling system is updated using the new BIOS retrieved from the ESP.read more

TL;DR: In this paper, a data structure is defined to associate each updateable resource with a corresponding identifier to enumerate the updateable resources to the firmware update system, which can be configured to handle firmware updates in a consistent manner across different computing platforms/architectures.
Patent
Trusted support processor authentication of host BIOS/UEFI
TL;DR: In this paper, a host processor is in communication with the memory component via the system interconnect to execute the BIOS instructions to configure the information handling system (IHS) to prevent execution of corrupted bootup instructions in flash memory.
