Abstract
An operating system (OS) may communicate with a basic input/output system (BIOS) at OS runtime to inform the BIOS of a firmware update storage location. A method may begin with receiving, by an OS, an update for a firmware of an information handling system. The OS may select a memory for storage of the firmware update and may store the firmware update in the selected memory. The OS may then store a location of the firmware update in a portion of a memory accessible by both the OS and the BIOS.
