Abstract: System and method for device support. The system may comprise a processor, a memory, a device controller and a basic input-output system (BIOS). The memory may be mapped according to a predetermined specification, such as the Advanced Configuration and Power Interface (ACPI) specification. A device support component in the BIOS uses a portion of a defined region of the memory, such as the non-volatile sleeping (NVS) memory region, to maintain device data for a device. A method involves providing the software component in the BIOS. The software component maps the memory, reserving a portion of the defined region of the memory to maintain a plurality of device data regarding the device controller, and provides support for at least one device utilizing the portion of the defined region of the memory. The system and method may be used with Universal Serial Bus (USB) devices and controllers, as well as with secondary graphics adapters.
