Update of boot code handlers

A method comprising:

• based on execution of a portion of a first version of boot firmware code by a processor, generating a region in memory of a size to store the first version of boot firmware code and a second version of boot firmware code and
• based on a detected indication of an update to boot firmware code, storing a portion of the second version of boot firmware code in the region in the memory, wherein:
• the first version of boot firmware code is associated with a first System Management Interrupt (SMI) handler,
• the second version of boot firmware code is associated with a second SMI handler,
• the second SMI handler comprises an alternate version of the first SMI handler,
• the first SMI handler and the second SMI handler are stored simultaneously in the memory;
• and
• performing a portion of the second version of the boot firmware code by executing the second SMI handler.

At least one non-transitory computer-readable medium, comprising instructions stored thereon, that if executed by one or more processors, cause the one or more processors to:

• allocate a region in memory that is hidden from an operating system (OS), wherein the region is to store at least a first version of boot firmware code and a second version of boot firmware code;
• based on an indication of a second version of a boot firmware code and authentication of the second version of the boot firmware code, copy a portion of the second version of the boot firmware code into the region, wherein:
• the first version of boot firmware code is associated with a first System Management Interrupt (SMI) handler,
• the second version of boot firmware code is associated with a second SMI handler,
• the second SMI handler comprises an alternate version of the first SMI handler,
• the first SMI handler and the second SMI handler are stored simultaneously in the memory;
• and
• perform a portion of the second version of boot firmware code by executing the second SMI handler.
