Abstract

A system (100) and a method (500) for managing boot errors. When errors occur during boot, the errors may be recorded in non-volatile storage (115). The errors in the non-volatile storage (115) may be retrieved, decoded, and displayed in a form more understandable to the user. Also, tie errors may be analyzed to efficiently detect and correct the causes of the errors. In addition, the analysis may be used to prevent errors altogether.

Claims

1. A data processing system comprising a boot error manager stored on a computer readable medium that is operable in the data processing system, comprising:

a processor; and

a memory, coupled to the processor, storing a plurality of instructions executed by the processor including instructions configured to boot and load an operating system stored in the memory, wherein the boot error manager comprises;

an error log module configured to log one or more boot errors of the data processing system in a non-volatile storage; and

an error processing module configured to process the one or more boot errors stored in the non-volatile storage, the error processing module comprising;

a retrieval module configured to retrieve the one or more boot errors from the non-volatile storage;

a decode module configured to decode the one or more boot errors retrieved by the retrieval module; and

a display module configured to display the one or more boot errors decoded by the decode module,

wherein the decode module is configured to decode boot errors for two or more data processing system types,

wherein the decode module is configured to access one or more tables that include boot error information for the two or more data processing system types to account for variances in the two or more data processing system types, and

wherein boot error decoding information is undated by the decode module based on the variances accounted for by the decode module.

2. The data processing system of claim 1, wherein the error processing module further comprises one or more of:

a localization module configured to interpret the one or more boot errors in one or more languages; and

an analysis module configured to analyze the one or more boot errors,

wherein a type of analysis performed by the analysis module includes one or more of a historical analysis and a statistical analysis, and

wherein the statistical analysis determines most problematic components or combination of problematic components in the data processing system.

3. The data processing system of claim 2, wherein the display module is configured to display one or more of:

the one or more boot errors interpreted in the one or more languages by the localization module; and

the one or more boot errors analyzed by the analysis module.

4. The data processing system of claim 1, wherein one or more of the error log module, the retrieval module, the decode module, and the display module reside in two or more data processing systems in which a first portion of the error log module, the decode module and the display module are located on a first data processing system and a second portion of the error log module, the decode module and the display module are located on a second data processing system.

5. The data processing system of claim 1, wherein one or more of the error log module, the retrieval module, the decode module, and the display module are implemented as instructions in BIOS, as software programs, as dedicated firmware, in hardware, and any combination thereof.

6. The data processing system of claim 1, wherein each of the one or more boot errors is stored by the error log module in the non-volatile memory with an error code and a time stamp corresponding to a recorded error time.

7. A method to manage boot errors of a data processing system, comprising:

logging boot errors of the data processing system in a non-volatile storage; and

retrieving the one or more boot errors from the non-volatile storage;

decoding the one or more boot errors retrieved in the retrieving step; and

displaying the one or more boot errors decoded in the decoding step,

wherein the decode step decodes boot errors for two or more data processing system types,

wherein the decoding step further comprises;

accessing one or more tables that include boot error information for the two or more data processing system types;

based on the boot error information accessed from the one or more tables, accounting for variances in the two or more data processing system types, and

updating boot error decoding information based on the variances accounted for.

8. The method of claim 7, wherein the decoding step comprises:

decoding boot errors for one or more data processing system types.

9. The method of claim 7, further comprising:

interpreting the one or more boot errors in one or more languages; and

analyzing the one or more boot errors, wherein a type of analysis performed includes one or more of a historical analysis and a statistical analysis.

10. The method of claim 9, wherein the step of displaying further comprises one or more of:

displaying the one or more boot errors interpreted in the interpreting step; and

displaying the one or more boot errors analyzed in the analyzing step.

11. The method of claim 7, further comprising:

interpreting the one or more boot errors in one or more languages; and

analyzing the one or more boot errors,

wherein a type of analysis performed by the analyzing step includes one or more of a historical analysis and a statistical analysis; and

determining most problematic components or combination of problematic components in the data processing system based on results of the analyzing step.
