Mechanism for obviating the need for host-side basic input/output system (BIOS) or boot serial peripheral interface (SPI) device(s)

The present disclosure describes several embodiments, e.g., a method, a baseboard management controller (BMC) system, a computer-readable non-transitory medium, for managing boot images for a computer system. These embodiments may include obtaining, by a BMC of the BMC system, a first boot image for the processor-based system, storing, by the BMC of the BMC system, the first boot image at a first location in a memory element of BMC system, and informing, by the BMC of the BMC system to a bus-to-memory bridge, first location information indicating a first location at which the first boot image is stored. The present disclosure also describes the bus-to-memory bridge which interfaces between a bus of the processor-based system and the memory element of the BMC system to allow one or more processors of the processor-based system to access the memory element of the BMC system to obtain boot image(s).
