The pattern is 0x5A5AC3C3A5A53C3C. + * + * HEADER SIZE (Bytes) + * ------------------- + * The header size is the next longword. This is provided + * to allow for some backward compatibility in the event that + * the header is extended in the future. When the header + * is located, current versions of SROM code determine where + * the image begins based on the header size. Additional data + * added to the header in the future will simply be ignored + * by current SROM code. Additionally, the header size = 0x20 + * implies version 0 of this header spec. For any other size + * see HEADER REVISION to determine header version. + * + * + * IMAGE CHECKSUM + * -------------- + * The next longword contains the image checksum. This is + * used to verify the integrity of the ROM. Checksum is computed + * in the same fashion as the header checksum. + * + * IMAGE SIZE (Memory Footprint) + * ----------------------------- + * The image size reflects the size of the image after it has + * been loaded into memory from the ROM. See ROM IMAGE SIZE. + * + * DECOMPRESSION FLAG + * ------------------ + * The decompression flag tells the SROM code if the makerom + * tool was used to compress the ROM image with a "trivial + * repeating byte algorithm". The SROM code contains routines + * which perform this decompression algorithm. Other + * compression/decompression schemes may be employed which work + * independently from this one. + * + * DESTINATION ADDRESS + * ------------------- + * This quadword contains the destination address for the + * image. The SROM code will begin loading the image at this + * address and subsequently begin its execution there. + * + * HEADER REV + * ---------- + * The revision of the header specifications used in this + * header. This is necessary to provide compatibility to + * future changes to this header spec. Version 0 headers + * are identified by the size of the header. See HEADER + * SIZE. + * + * FIRMWARE ID + * ----------- + * The firmware ID is a byte that specifies the firmware type. + * This facilitates image boot options necessary to boot + * different operating systems. + * + * firmware + * firmware type + * -------- -------- + * DBM 0 Alpha Evaluation Boards Debug Monitor + * WNT 1 Windows NT Firmware + * SRM 2 Alpha System Reference Manual Console + * + * ROM IMAGE SIZE + * -------------- + * The ROM image size reflects the size of the image as it is + * contained in the ROM. See IMAGE SIZE. + * + * OPTIONAL FW ID + * -------------- + * This is an optional field that can be used to provide + * additional firmware information such as firmware revision + * or a character descriptive string up to 8 characters. + * + * HEADER CHECKSUM + * --------------- + * The checksum of the header. This is used to validate + * the presence of a header beyond the validation provided + * by the validation pattern. See VALIDATION PATTERN. + * The header checksum is computed from the beginning of + * the header up to but excluding the header checksum + * field itself. If there are future versions of this + * header the header checksum should always be the last + * field defined in the header. The checksum algorithm used + * is compatible with the standard BSD4.3 algorithm provided + * on most implementations of Unix.
