Abstract
A read-only memory (ROM) stores firmware code for a hardware component. A firmware controller is directly physically connected to the hardware component and to the ROM. The firmware controller exposes a virtual ROM link to the hardware component. The hardware component accesses the firmware code over the virtual ROM link exposed by the firmware controller.
