Abstract:
An update-startup apparatus includes: an OS startup processor unit configured to start a first OS and a second OS; an initial startup processor unit configured to start the OS startup processor unit; and an update information storage unit configured to store first OS update information for updating a first OS program constituting the first OS and second OS update information for updating a second OS program constituting the second OS. The OS startup processor unit starts the first OS after updating the first OS program by using the first OS update information, when the first OS update information is stored at a time of power-on or at a time of rebooting the first OS; the OS startup processor unit starts the first OS, when the first OS update information is not stored at a time of power-on; and the OS startup processor unit cancels a reboot of the second OS, when the second OS update information is not stored at a time of rebooting the first OS.
