System and method for self-healing basic input/output system boot image and secure recovery

1. A method comprising:

detecting, at a baseboard management controller (BMC), a basic input/output system (BIOS) boot failure on a host central processing unit (CPU);

directing by the BMC, the host CPU to reboot to a non-volatile memory device to obtain a recovery image, the recovery image comprising instructions to perform a system software management (SSM) task;

executing, by the host CPU, the instructions to perform the SSM task, wherein the executing comprises:

loading a BIOS image from a persistent storage memory device attached to the BMC;

verifying the BIOS image; and

writing the BIOS image to a BIOS non-volatile memory device.

2. The method of claim 1 wherein the obtaining from the non-volatile memory device the recovery image comprises:

obtaining the recovery image using a recovery flash memory device attached to the BMC.

3. The method of claim 1 wherein the obtaining from the non-volatile memory device the recovery image comprises:

obtaining the recovery image using a recovery flash memory device attached to a southbridge portion of a chipset.

4. The method of claim 3 wherein the writing the BIOS image to the BIOS non-volatile memory device comprises:

writing the BIOS image using a recovery flash memory device attached to the BMC.

5. The method of claim 1 wherein the writing the BIOS image to the BIOS non-volatile memory device comprises:

writing the BIOS image using a recovery flash memory device attached to a southbridge portion of a chipset.

6. The method of claim 1 wherein the BIOS non-volatile memory device is the non-volatile memory device.

7. The method of claim 1 wherein the detecting is performed based on an occurrence of a BIOS event and a timing of a timer.

8. The method of claim 1 wherein in directing the host CPU to reboot to the non-volatile memory device to obtain the recovery image, the method further comprises:

setting a strapping option in a southbridge, wherein the CPU reboots to the non-volatile memory device in response to the strapping option being set.

9. An information handling system comprising:

a host central processing unit (CPU);

a platform controller hub (PCH) coupled to the host CPU;

a basic input/output system (BIOS) non-volatile memory coupled to the PCH;

a baseboard management controller (BMC) coupled to the PCH; and

a BMC persistent storage memory device coupled to the BMC, wherein the BMC is configured to detect a basic input/output system (BIOS) boot failure on the host CPU, the BMC is configured to direct the host CPU to reboot to a non-volatile memory device to execute a recovery image, the recovery image comprising instructions to perform a system software management (SSM) task, and to execute the instructions to perform the SSM task so as to load a BIOS image from the BMC persistent storage memory device, to verify the BIOS image, and to write the BIOS image to a BIOS non-volatile memory device.

10. The information handling system of claim 9 wherein, to obtain the recovery image, the processor is configured to use a recovery flash memory device attached to the BMC.

11. The information handling system of claim 9 wherein, to obtain the recovery image, the processor is configured to use a recovery flash memory device attached to the PCH.

12. The information handling system of claim 11 wherein, to write the BIOS image, the processor is configured to use a recovery flash memory device attached to the BMC.

13. The information handling system of claim 9 wherein, to write the BIOS image, the processor is configured to use a recovery flash memory device attached to the PCH.

14. The information handling system of claim 9 wherein the BIOS non-volatile memory device is the non-volatile memory device.

15. The information handling system of claim 9 wherein the BMC is configured to detect the BIOS boot failure based on an occurrence of a BIOS event and a timing of a timer.

16. The information handling system of claim 9 wherein in directing the host CPU to reboot to the non-volatile memory device, the BMC is further configured to set a strapping option in a southbridge, wherein the CPU reboots to the non-volatile memory device in response to the strapping option being set.

17. A method comprising:

detecting, at a baseboard management controller (BMC), a basic input/output system (BIOS) boot failure on a host central processing unit (CPU);

directing, by the BMC, the host CPU to reboot to a non-volatile memory device to obtain a recovery image, the recovery image comprising instructions to perform a system software management (SSM) task;

executing, by the host CPU, the instructions to perform the SSM task, wherein the executing comprises:

loading a BIOS image from a persistent storage memory device attached to the BMC;

verifying the BIOS image; and

writing the BIOS image to a BIOS non-volatile memory device, wherein a recovery flash memory device selected from a group consisting of the recovery flash memory device attached to the BMC and the recovery flash memory device attached to a southbridge portion of a chipset coupled to the CPU is used to perform at least one of the obtaining and the executing.

18. The method of claim 17 wherein the BIOS non-volatile memory device is the non-volatile memory device.

19. The method of claim 17 wherein in directing the host CPU to reboot to the non-volatile memory device to obtain the recovery image, the method further comprises:

setting a strapping option in a southbridge, wherein the CPU reboots to the non-volatile memory device in response to the strapping option being set.
