Filed:

Jun 18, 2020

Appl. No.:

16/905668

Inventors:

- Round Rock TX, US
Zhao Hui Yu - Cedar Park TX, US

International Classification:

G06F 8/654
G06F 9/4401
G06F 1/3206

Abstract:

An information handling system includes power inputs, a battery, a BMC, a memory, and a processor. The BMC determines which of the power inputs are coupled to associated power sources, and a first duration of time that the battery can provide power to the information handling system. The memory stores a firmware element. The processor receives a firmware that includes a second indication as to which of the power inputs are to be coupled to their associated power source as a condition for saving the firmware update, and that includes a second duration of time that it is expected to take to save the firmware update. The information handling system saves the firmware update to the memory when the first indication matches the second indication and when the first duration of time is greater than the second duration of time.

Assignee:

Dell Products L.P. - Round Rock TX

International Classification:

G06F 8/65

Abstract:

An information handling system may include at least one processor, an information handling resource including a firmware, and a memory having an initial identifier stored therein. The information handling system may receive a first firmware update package specifying the initial identifier, wherein the first firmware update package includes therein an intermediate identifier different from the initial identifier; based on the first firmware update package specifying the initial identifier, update the firmware with contents of the first firmware update package, and update the initial identifier in the memory with the intermediate identifier; receive a second firmware update package specifying the intermediate identifier; and based on the second firmware update package specifying the intermediate identifier, update the firmware with contents of the second firmware update package.

Abstract:

Systems and methods are provided that that may be implemented to detect and optionally recover corrupted data written to non-volatile random access memory (NVRAM), e.g., such as corrupted system configuration data (e.g., UEFI variables) stored in the NVRAM. The disclosed systems and methods may be implemented by writing a copy of the NVRAM data to volatile system memory (e.g., RAM) while the system is active, and satisfying requests to read data from the copy maintained in volatile RAM. Error correction code (ECC) data may written to the NVRAM when the system enters a lower power state. When the system resumes from the low power state, the copy of data is made in system RAM from the NVRAM, and the ECC data is used to determine whether there are errors in NVRAM data, in which case the ECC data may be used to correct data in the copy on RAM before writing the corrected data to NVRAM from the system RAM.
