Abstract: PURPOSE: A booter managing method in a communication system is provided to remove necessity for a maintenance person to directly move by constructing a booter (a bug, a booter, a loader) wanting correcting and complementing as a flash memory and thus enabling change from a remote area using an inter-processor communication. CONSTITUTION: When a power is applied to a board of a communication system(S11), a flash memory enables a dumper(S12) to copy a RAMBUG of the flash memory to an SRAM(S13). The dumper enables the RAMBUG in the SRAM(S14). When there is a change to a bug, a booter and/or a loader, a maintenance center transmits the changed content through the inter-processor communication to the board, the flash memory receives it(S15) and a CPU of the board checks an integrity of the bug, the booter and/or the loader. The existing bug, the booter and the loader are backup to the flash memory(S16). At this time, they are backup to a temporary section of the flash memory. The fresh bug, booter and loader transmitted through the inter-processor communication are updated in the flash memory. The processor is rebooted to perform the bug, the booter and the loader(S18). It is determined whether an error has occurred(S19). If an error has occurred, an exception handler substitutes the new RAMBUG with error with the existing RAMBUG which has been stored in the temporary section of the flash memory, logs the fact to the maintenance center and reboots the existing RAMBUG(S20).
