Abstract
In at least some embodiments, a method comprises receiving a first command from a source external to a computer to provide a copy of a read only memory (ROM) image from the computer to the external source. The method also comprises receiving a second command from the source external to the computer to replace the computer's ROM image and, without re-booting the computer, replacing the computer's ROM image with a ROM image received from the external source.
Claims26
A method, comprising:
- receiving a first command from a source external to a computer to provide a copy of a read only memory (ROM) image from said computer to said external source;
- receiving a second command from the source external to said computer to replace the computer's ROM image;
- without re-booting said computer, replacing the computer's ROM image with a ROM image received from the external source.
A method implemented in a computer, comprising:
- a management processor in said computer receiving a first command from a source external to said computer to provide a copy of a read only memory (ROM) image from said computer to said external source;
- the management processor receiving a request from the external source to update the computer's ROM image;
- without having to re-boot said computer, the management processor updating the computer's ROM image with an image received from said external source;
- wherein said management processor receives the first and second commands and updates the computer's ROM image even while a host processor in the computer is in a non-operational state.
1 more element
A system, comprising:
- a management processor;
- and
- a read only memory (ROM) coupled to said management processor;
- wherein, upon request from a device external to said system, said management processor provides a copy of an executable ROM image currently stored in said ROM to the external device and receives a replacement executable ROM image from the external device.
1 more element
A system, comprising:
- a host processor;
- a management processor;
- and
- a read only memory (ROM) coupled to said management processor and said host processor;
- wherein, upon request from a device external to said system, said management processor flashes the ROM with a replacement executable ROM image even while said host processor is in a non-operational state
2 more elements
A system, comprising:
- means for storing boot code;
- and
- means for replacing said boot code with new boot received from a device external to said system while a host processor is in a non-operational state or while the host processor is actively executing.
