<P>PROBLEM TO BE SOLVED: To provide an image formation device capable of restoring a program without mounting a rescue on a device. <P>SOLUTION: An RRU application receiving a start address of an updated data area and the area size of the updated data area by a ROM update mode thread of MCS eliminates network information and develops an updated data packet from the start address of the updated data area given by the ROM update mode thread of MCS (S11), and then reads the setting of a net boot address of NVRAM. An access is actually made by using a tftp protocol to check if the net boot address is authentic (S12). In a case of success, a copy of a usual system from a program storing medium is put by using the tftp protocol (S14). When the program storing medium is a flash memory, the copy is put after retrieval from the memory. When the program storing medium is a flash card, the copy is put with leaving a file as it is. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
