Abstract
Abstract A bootloading system in a multiprocessor system down-loads programs from an auxiliary memory device into a plurality of volatile memories when a power source is switched on. A common loader ROM (42) is shared by boards, and when the power source is turned on, the programs are down-loaded into the volatile memories (12, 22, 32) of respective processors (11, 21, 31) according to a program stored in the loader ROM (42). The number of loader ROMs is reduced, and loading control is simplified.
