SYSTEM AND METHOD OF COMPOSING AND DECOMPOSING A ROM IMAGE

A decomposable ROM image sequentially including an OS header corresponding to an OS image, the OS image, a non-OS header corresponding to a non-OS image and the non-OS image. To compose the decomposable ROM image, the OS header, which includes OS size information of the OS image and the non-OS header, which includes non-OS size information of the non-OS image are created first. Then, the OS header, the OS image, the non-OS header and the non-OS image are sequentially combined. To decompose the decomposable ROM image, the OS image is retrieved from the ROM image according to the OS size information obtained from the OS header. The non-OS image is then retrieved from the ROM image according to the non-OS size information obtained from the non-OS header.
