and a basic input/output system comprising a program of instructions executable by the processor and configured to cause the processor to: perform preboot healing of firmware to address stop error code crashes wherein the preboot healing of firmware includes; determining if a captured stop error code captured in connection with an operating system stop error occurring during a previous boot session of the information handling system exists on a memory accessible to the basic input/output system; and responsive to the captured stop error code existing on the memory: reading the captured stop error code; and performing a remedial action based on the captured stop error code. ### Claim 2 (depends on 1) The information handling system of claim 1, wherein the preboot healing of firmware includes: responsive to no captured stop error code existing on the memory, allowing the information handling system to proceed to an operating system boot session; and in the event of an operating system stop error occurring during the operating system boot session, and in concert with an operating system of the information handling system, capturing a stop error code generated in connection with the operating system stop error and store the stop error code in the memory. ### Claim 3 (depends on 1) The information handling system of claim 1, wherein the remedial action comprises returning configuration settings of the basic input/output system to a known good configuration in which the last operating system boot of the information handling system was successful. ### Claim 4 (depends on 1) The information handling system of claim 1, wherein the remedial action comprises initiating an update for firmware of the basic input/output system. ### Claim 5 (depends on 1) The information handling system of claim 1, wherein the remedial action comprises performing diagnostic tests to identify any hardware information handling resources of the information handling system that potentially caused the operating system stop error. ### Claim 6 (depends on 1) The information handling system of claim 1, wherein the remedial action comprises communicating the captured stop error code to a service operating system to enable the service operating system to attempt to identify and repair problems leading to the operating system stop error. ### Claim 7 (depends on 1) The information handling system of claim 1, wherein the remedial action comprises communicating suggestions to a user of the information handling system to perform in an attempt to eliminate stop errors on a subsequent operating system boot of the information handling system. ### Claim 8 A method comprising: perform preboot healing of firmware to address stop error code crashes wherein the preboot healing of firmware includes; determining, with a basic input/output system of an information handling system, if a captured stop error code captured in connection with an operating system stop error occurring during a previous boot session of the information exists on a memory accessible to the basic input/output system; and responsive to the captured stop error code existing on the memory: reading the captured stop error code; and performing a remedial action based on the captured stop error code. ### Claim 9 (depends on 8) The method of claim 8, further comprising, with the preboot healing of firmware includes: responsive to no captured stop error code existing on the memory, allowing the information handling system to proceed to an operating system boot session; and in the event of an operating system stop error occurring during the operating system boot session, and in concert with an operating system of the information handling system, capturing a stop error code generated in connection with the operating system stop error and storing the stop error code in the memory. ### Claim 10 (depends on 8) The method of claim 8, wherein the remedial action comprises returning configuration settings of the basic input/output system to a known good configuration in which the last operating system boot of the information handling system was successful. ### Claim 11 (depends on 8) The method of claim 8, wherein the remedial action comprises initiating an update for firmware of the basic input/output system. ### Claim 12 (depends on 8) The method of claim 8, wherein the remedial action comprises performing diagnostic tests to identify any hardware information handling resources of the information handling system that potentially caused the operating system stop error. ### Claim 13 (depends on 8) The method of claim 8, wherein the remedial action comprises communicating the captured stop error code to a service operating system to enable the service operating system to attempt to identify and repair problems leading to the operating system stop error. ### Claim 14 (depends on 8) The method of claim 8, wherein the remedial action comprises communicating suggestions to a user of the information handling system to perform in an attempt to eliminate stop errors on a subsequent operating system boot of the information handling system. ### Claim 15 An article of manufacture comprising: a non-transitory computer readable medium; and computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to, in a basic input/output system of an information handling system: perform preboot healing of firmware to address stop error code crashes wherein the preboot healing of firmware includes; determining if a captured stop error code captured in connection with an operating system stop error occurring during a previous boot session of the information handling system exists on a memory accessible to the basic input/output system; and responsive to the captured stop error code existing on the memory: reading the captured stop error code; and performing a remedial action based on the captured stop error code. ### Claim 16 (depends on 15) The article of claim 15, the preboot healing of firmware includes: responsive to no captured stop error code existing on the memory, allowing the information handling system to proceed to an operating system boot session; and in the event of an operating system stop error occurring during the operating system boot session, and in concert with an operating system of the information handling system, capturing a stop error code generated in connection with the operating system stop error and store the stop error code in the memory. ### Claim 17 (depends on 15) The article of claim 15, wherein the remedial action comprises returning configuration settings of the basic input/output system to a known good configuration in which the last operating system boot of the information handling system was successful. ### Claim 18 (depends on 15) The article of claim 15, wherein the remedial action comprises initiating an update for firmware of the basic input/output system. ### Claim 19 (depends on 15) The article of claim 15, wherein the remedial action comprises performing diagnostic tests to identify any hardware information handling resources of the information handling system that potentially caused the operating system stop error. ### Claim 20 (depends on 15) The article of claim 15, wherein the remedial action comprises communicating the captured stop error code to a service operating system to enable the service operating system to attempt to identify and repair problems leading to the operating system stop error. ### Claim 21 (depends on 15) The article of claim 15, wherein the remedial action comprises communicating suggestions to a user of the information handling system to perform in an attempt to eliminate stop errors on a subsequent operating system boot of the information handling system.
