Abstract
Abstract A method and apparatus in a data processing system for automatically restoring an operating system on a local storage device. Prior to loading the operating system, a determination is made as to whether the operating system on the local storage device is corrupted in response to starting the data processing system. If the operating system is corrupted, the operating system is repaired using code from a source storage device without loading the operating system.

Independent Claim
65 words
A method for automatically restoring an operating system on a local storage device in a data processing system, comprising the steps of; determining whether the operating system on the local storage device is corrupted in response to starting the data processing system; and repairing the operating system using code from a source storage device without loading the operating system if the operating system is corrupted.
Claim 2
Independent Claim
65 words
A method for automatically restoring an operating system on a local storage device in a data processing system, comprising the steps of; determining whether the operating system on the local storage device is corrupted in response to starting the data processing system; and repairing the operating system using code from a source storage device without loading the operating system if the operating system is corrupted.

Claim 8
Dependent Claim
24 words
The method of claim 6 further comprising copying other portions of the operating system from the source storage device to the local storage device.
Claim 9
Dependent Claim
18 words
The method of claim 1 , wherein the determining and repairing steps are performed by a boot code.
Claim 10
Dependent Claim
22 words
The method of claim 8 , wherein the boot code is located in a non volatile memory in the data processing system.
Claim 11
Dependent Claim
32 words

Claim 12
Dependent Claim
29 words
The method of claim 1 , wherein error checking information is present on the data processing system and wherein the determining step is performed using the error checking information.
Claim 13
Dependent Claim
98 words
A data processing system comprising: a bus; a non volatile memory connected to the bus, wherein a boot code is located in the nonvolatile memory; a local storage device connected to the bus; and a processor connected to the bus, wherein the processor executes the boot code to determine whether an operating system is present in the local storage device, and copies the operating system from a remote location to the local storage device through a data link from the data processing system to the remote location if the operating system is absent from the local storage device.
Claim 14
Dependent Claim
98 words
A data processing system comprising: a bus; a non volatile memory connected to the bus, wherein a boot code is located in the nonvolatile memory; a local storage device connected to the bus; and a processor connected to the bus, wherein the processor executes the boot code to determine whether an operating system is present in the local storage device, and copies the operating system from a remote location to the local storage device through a data link from the data processing system to the remote location if the operating system is absent from the local storage device.
Claim 15
Dependent Claim
20 words
