Preserving firmware setting during firmware update

A system, comprising:

• a processor;
• and
• a computer-readable medium storing instructions that, when executed by the processor, cause the system to perform operations comprising:
• powering on the system;
• retrieving a plurality of future firmware settings from a component of the system, wherein the future firmware settings are firmware settings that need to be changed after a reboot;
• applying the plurality of future firmware settings to the system, wherein the applied plurality of future firmware settings is defined as current firmware settings currently on the server system;
• sending the plurality of the current firmware settings currently on the server system to the component in the form of unique strings, wherein each of the plurality of current firmware settings are mapped to a unique string;
• storing the plurality of current firmware settings on the component in the form of the unique strings;
• performing an entire firmware flash update;
• copying the plurality of current firmware settings stored on the component to replace the plurality of future firmware settings stored on the component;
• and
• rebooting the system by applying the replaced plurality of future firmware settings stored on the component.

A non-transitory computer-readable storage medium including instructions that, when executed by at least one processor of a system, cause the system to perform operations comprising:

• powering on the server system;
• retrieving a plurality of future firmware settings from a component of the server system, wherein the future firmware settings are firmware settings that need to be changed after a reboot;
• applying the plurality of future firmware settings to the server system, wherein the applied plurality of future firmware settings is defined as current firmware settings currently on the server system;
• sending the plurality of the current firmware settings currently on the server system to the component in the form of unique strings, wherein each of the plurality of current firmware settings are mapped to a unique string;
• storing the plurality of current firmware settings on the component in the form of the unique strings;
• performing an entire firmware flash update;
• copying the plurality of current firmware settings stored on the component to replace the plurality of future firmware settings stored on the component;
• and
• rebooting the server system by applying the replaced plurality of future firmware settings stored on the component.
