Microcode update system

An Information Handling System (IHS), comprising:

• a processing system that includes at least one hardware processor that is configured to execute instructions that cause the processing system to provide a microcode update engine that is configured to:
• receive a microcode update;
• write the microcode update to a data region of at least one memory device;
• perform, subsequent to writing the microcode update to the data region of the at least one memory device utilizing initialization code in a code region of the at least one memory device, and utilizing existing microcode that is to be updated with the microcode update, initialization operations, wherein the microcode update is provided without an initialization code update for the initialization code;
• identify, during a microcode update portion of the initialization operations, the microcode update in the data region of the at least one memory device;
• and
• perform microcode update operations using the microcode update in the data region of the at least one memory device.

A method for updating microcode, comprising:

• receiving, by a microcode update engine provided via operation of a processing system in a computing device, a microcode update;
• writing, by the microcode update engine, the microcode update to a data region of at least one memory device;
• performing, by the microcode update engine subsequent to writing the microcode update to the data region of the at least one memory device, utilizing initialization code in a code region of the at least one memory device, and utilizing existing microcode that is to be updated with the microcode update, initialization operations, wherein the microcode update is provided without an initialization code update for the initialization code;
• identifying, by the microcode update engine during a microcode update portion of the initialization operations, the microcode update in the data region of the at least one memory device;
• and
• performing, by the microcode update engine, microcode update operations using the microcode update in the data region of the at least one memory device.
