AUTOMATED BASIC INPUT/OUTPUT SYSTEM (BIOS) RECOVERY

1 . A computer-implemented method, comprising:

attempting to boot an operating system (OS) from a Basic Input/Output System (BIOS) while running an Intelligent Platform Management Interface (IPMI) watchdog timer, the BIOS being stored in a first partition of a memory of a communication device in a wireless communication system;

after a timeout of the watchdog timer, automatically triggering performance of a BIOS recovery procedure; and

after the performance of the BIOS recovery procedure, automatically re-attempting to boot the OS from the BIOS.

2 . The method of claim 1 , further comprising, after the timeout of the watchdog timer and before triggering the performance of the BIOS recovery procedure, incrementing a failure counter; and

determining if the failure counter is less than a threshold;

wherein the performance of the BIOS recovery procedure is triggered in response to determining that the failure counter is not less than the threshold.

3 . The method of claim 2 , further comprising, in response to determining that the failure counter is less than the threshold, re-attempting to boot the OS from the BIOS without triggering the performance of the BIOS recovery procedure.

4 . The method of claim 2 , wherein the failure counter is zero when the OS is attempted to be booted from the first BIOS; and

the method further comprises resetting the failure counter to zero in response to determining that the failure counter is not less than the threshold.

5 . The method of claim 2 , wherein the failure counter is zero when the OS is attempted to be booted from the first BIOS; and

the method further comprises, in response to the timeout of the watchdog timer, incrementing the failure counter by one.

6 . The method of claim 1 , wherein attempting to boot the OS includes a BIOS Power On Self Test (POST) attempt; and

the timeout of the watchdog timer occurs during the BIOS POST attempt.

7 . The method of claim 1 , wherein attempting to boot the OS includes an attempt to load the OS; and

the timeout of the watchdog timer occurs during the OS load attempt.

8 . The method of claim 1 , wherein the timeout of the watchdog timer includes timeout of at least one of a BIOS Fault Resilient Booting level 2 (FRB2) timeout, a BIOS FRB level 3 (FRB3) timeout, and a BIOS Power On Self Test (POST) timeout.

9 . The method of claim 1 , wherein performing the BIOS recovery procedure includes copying a golden BIOS image stored in a second partition of the memory of the communication device to the BIOS.

10 . The method of claim 9 , wherein the golden BIOS image was pre-stored in the second partition of the memory during manufacturing of the communication device.

11 . The method of claim 1 , wherein the communication device is a distributed unit (DU).

12 . The method of claim 1 , wherein at least one of the attempting and the automatically attempting is performed by a base station in the wireless communication system.

13 . The method of claim 12 , wherein the base station includes at least one of an eNodeB base station, a gNodeB base station, a wireless base station, and any combination thereof.

14 . The method of claim 1 , wherein the wireless communication system is at least one of a long term evolution communications system, a new radio communications system, and any combination thereof.

15 . An apparatus, comprising:

at least one processor, and

at least one non-transitory storage media storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:

attempting to boot an operating system (OS) from a Basic Input/Output System (BIOS) while running an Intelligent Platform Management Interface (IPMI) watchdog timer, the BIOS being stored in a first partition of a memory of a communication device in a wireless communication system,

after a timeout of the watchdog timer, automatically triggering performance of a BIOS recovery procedure, and

after the performance of the BIOS recovery procedure, automatically re attempting to boot the OS from the BIOS.

16 - 28 . (canceled)

29 . At least one non-transitory storage media storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

attempting to boot an operating system (OS) from a Basic Input/Output System (BIOS) while running an Intelligent Platform Management Interface (IPMI) watchdog timer, the BIOS being stored in a first partition of a memory of a communication device in a wireless communication system;

after a timeout of the watchdog timer, automatically triggering performance of a BIOS recovery procedure; and

after the performance of the BIOS recovery procedure, automatically re attempting to boot the OS from the BIOS.
