In an embodiment, a computing device may include a control unit. The control unit may acquire a request from a central processing unit (CPU), contained in the computing device, that may be executing a basic input/output system (BIOS) associated with the computing device. The request may include a request for a value that may represent a maximum authorized storage size for a storage contained in the computing device. The control unit may generate the value and send the value to the CPU. The CPU may generate a system address map based on the value. The CPU may send the system address map to the control unit which may acquire the system address map and configure an address decoder, contained in the computing device, based on the acquired system address map.
