Abstract
A processor-based system performs automatic reboot for some initialization failures. The processor-based system runs an operating system. When initialization failures occur, the operating system may reboot the processor-based system and control the direction of a power-on routine. The power-on routine may send a page to a remote processor-based system, enter an emergency mode of operation, update system software, or perform other operations.
Claims19
A method, comprising:
- identifying an initialization failure on a processor-based system during execution of an operating system program;
- sending an indicator to a memory location in response to the initialization failure;
- initiating a power-on program to read the memory location;
- and
- executing a predetermined set of operations by the power-on program based upon the indicator.
2 more elements
A system, comprising:
- a processor;
- a memory coupled to the processor;
- and
- a storage medium coupled to the processor including a software program that, upon execution:
- identifies an initialization failure on the system;
- sends an indicator to the memory in response to the initialization failure;
- initiates a power-on program to read the memory;
- and
- executes a predetermined set of operations by the power-on program based upon the indicator.
6 more elements
An article comprising a medium storing software that causes a processor-based system to:
- identify an initialization failure during execution of an operating system program;
- send an indicator to a memory location in response to the initialization failure;
- initiate a power-on program to read the memory location;
- and
- execute a predetermined set of operations by the power-on program based upon the indicator.
2 more elements
A method, comprising:
- identifying an initialization failure on a first processor-based system;
- sending an indicator of the initialization failure to a second processor-based system;
- receiving a command from the second processor-based system;
- and
- performing an operation on the first processor-based system in response to the initialization failure.
