Caching unified extensible firmware interface (UEFI) and/or other firmware instructions in a non-volatile memory of an information handling system (IHS)

摘要

Systems and methods for caching firmware instructions in a non-volatile memory of an information handling system (IHS). In an illustrative, non-limiting embodiment, an IHS may include a processor, a non-volatile memory coupled to the processor, and a unified extensible firmware interface (UEFI) chipset coupled to the processor. The processor may be configured to: copy instructions stored in the UEFI chipset to the non-volatile memory prior to a reboot or restart of the HIS, and, at least in part in response to the reboot or restart operation, load at least a subset of the instructions directly from the non-volatile memory rather than from the UEFI chipset as part of a fast boot mode of operation.

1. An Information Handling System (IHS), comprising:
a processor; a non-volatile memory coupled to the processor; and a unified extensible firmware interface (UEFI) chipset coupled to the processor, wherein the processor is configured to:
copy instructions stored in the UEFI chipset to the non-volatile memory prior to a reboot or restart of the IHS, wherein the non-volatile memory includes a non-volatile dual in-line memory module (NVDIMM);at least in part in response to the reboot or restart operation, load at least a subset of the instructions directly from the non-volatile memory rather than from the UEFI chipset as part of a fast boot mode of operation; anddetermine whether the NVDIMM is installed in the IHS, and, at least in part in response to the NVDIMM being installed in the IHS, enter the fast boot mode of operation.
