Abstract
A computing device includes an accessory containing an option ROM, a first processor adapted to boot the computing device and to execute the option ROM, and a second processor adapted to be activated by the first processor to monitor execution of the option ROM by the first processor. The second processor is adapted to restore the first processor to a state prior to execution of the option ROM in response to the first processor becoming hung during execution of the option ROM. A computer program product includes program instructions executable by a processor to monitor execution of the option ROM by a first processor of a computing device, determine whether the first processor has become hung during execution of the option ROM, and restore the first processor to an execution environment that the first processor had prior to execution of the option ROM.
