1. A method for coping with OS failures, said method comprising:
- starting up a first OS by loading the first OS onto a memory of a computer;
loading a second OS onto the memory by securing a second OS area not erased from the first OS;
starting up the second OS upon detection of a failure in the first OS; and
executing failure processing of the first OS under control of the second OS.

Abstract
In provision against an unrecoverable failure in a first OS, a second OS for undertaking failure processing is loaded onto a memory beforehand. On detecting a failure in the first OS, a gate driver saves the first OS, moves the second OS to its executable area within the memory, and starts up the second OS. After this, control is transferred to a failure-processing application program placed under the control of the second OS.

9. A program allowing a computer in which a first OS operates to execute:
-
a function which secures an area of a second OS not erased from the first OS, and loads the second OS onto a memory of the computer;
a function which starts up the second OS when a failure in the first OS is detected; and
a function which transfers control to a failure-processing application program executed under control of the second OS. - View Dependent Claims (10, 11, 12, 13, 14, 15)
