Booting firmware from expansion block storage devices

Abstract:

Systems, apparatuses and methods may provide for technology to determine one or more default values associated with a block storage device and automatically retrieve boot code from the block storage device in accordance with the default value(s), wherein the boot code is retrieved via an expansion bus. In an example, the default value(s) include bus number information and address information, wherein the address information corresponds to a bus header of the block storage device. Moreover, the block storage device may be dedicated to the bus controller and retrieval of the boot code from the block storage device may bypass a bus enumeration procedure.
