Abstract
A method and system recover from a failure of an operational software program. A second software program which is known to function properly and is capable of downloading an updated copy of operational software is stored on the computer with the first software program. The second software program is a boot program which monitors resets of the first software program, determines if the number of resets which have occurred without the operational software first having reached a set operating point (such as establishing communication with a remote computer) reaches a threshold, and preempts operation of the first software program when the threshold is reached.
