Реферат: According to examples, an apparatus may include a processor that may delete portions of firmware instructions responsive to an indication that the portions should be disabled. To facilitate the foregoing, the firmware instructions may be deployed in a segmented architecture stored in respective regions of a storage device. The regions may include a metadata region, a main region, and excludable regions. The metadata region may store metadata that describes the structure of the firmware instructions and/or the various other regions. The main region may store core firmware instructions that may not be deleted. Each excludable region may store respective excludable firmware instructions. Each excludable firmware instructions may be associated with a flag that indicates whether or not the instructions should be disabled. If so, the corresponding excludable region in the storage device is identified and the contents may be removed, permanently disabling the excludable firmware instructions that were stored there.
