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.

Claims

1. An update-startup apparatus comprising:

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;

wherein,

the OS startup processor unit is configured to start 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 is configured to start the first OS, when the first OS update information is not stored at a time of power-on; and

the OS startup processor unit is configured to cancel a reboot of the second OS, when the second OS update information is not stored at a time of rebooting the first OS.

2. The update-startup apparatus according to claim 1, wherein,

the update information storage unit is configured to store update cancellation information for canceling an update of the first OS program when an update of a startup program constituting the OS startup processor unit is not completed;

the OS startup processor unit is configured to update the first OS program by using the first OS update information, when the update cancellation information is not stored at the time of power-on or at the time of rebooting the first OS; and

the OS startup processor unit is configured to cancel an update of the first OS program, when the update cancellation information is stored at the time of power-on or at the time of rebooting the first OS.

3. The update-startup apparatus according to claim 1, wherein

the update information storage unit is configured to store update cancellation information for canceling an update of a second OS program when an update of the first OS program is not completed;

the OS startup processor unit is configured to update the second OS program by using the OS update information, when the update cancellation information is not stored at the time of power-on or at a time of rebooting the second OS; and

the OS startup processor unit is configured to cancel an update of the second OS program, when the update cancellation information is stored at the time of power-on or at a time of rebooting the second OS.

4. The update-startup apparatus according to claim 2, wherein,

the OS startup processor unit is configured to delete the update cancellation information, when the startup program is updated.

5. The update-startup apparatus according to claim 3, wherein

the OS startup processor unit is configured to delete the update cancellation information, when the first OS program is updated.

6. The update-startup apparatus according to claim 1, wherein

the update information storage unit is configured to store startup update information for updating a startup program constituting the OS startup processor unit;

the initial startup processor unit is configured to update the startup program by using the startup update information, when the startup update information is stored at the time of power-on or at the time of rebooting the first OS or the second OS; and

the initial startup processor unit is configured to start the OS startup processor unit, when the startup update information is not stored at the time of power-on or at the time of rebooting the first OS or the second OS.

7. The update-startup apparatus according to claim 1, wherein

the update information storage unit is configured to store startup disabling information for canceling a startup of the second OS when an update of the first OS program is not completed;

the OS startup processor unit is configured to start the second OS, when the startup disabling information is not stored at the time of power-on or at a time of the second OS; and

the OS startup processor unit is configured to cancel a startup of the second OS, when the startup disabling information is stored at the time of power-on or before the second OS is rebooted.

8. The update-startup apparatus according to claim 7, wherein,

the OS startup processor unit is configured to delete the startup disabling information, when the first OS program is updated.

9. An update-startup control method, comprising:

(A) starting a first OS and a second OS;

(B) starting the step (A); and

(C) storing 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;

wherein

in the step (A), the first OS is started after the first OS program is updated 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;

in the step (A), the first OS is started, when the first OS update information is not stored at a time of power-on; and

in the step (A), a reboot of the second OS is cancelled, when the second OS update information is not stored at a time of rebooting the first OS.
