System and method to remotely recover from a system halt during system initialization

摘要

An information handling system includes a memory, a processor, and a management controller. The memory includes code to implement a power on self test (POST). The management controller operates to receive an indication that the POST has halted execution in response to a POST error, to log the indication and the POST error, and to send an input to the POST. The POST operates to receive the input and to continue execution based upon the input.

1. An information handling system comprising:
a memory including code to implement a power on self test (POST); a processor operable to execute the POST; and a management controller operable to:
receive a first indication that the POST has halted execution in response to a POST error;log the first indication and the POST error; andsend an input to the POST, wherein in sending the input the management controller is further operable to:
write a second indication to a memory of the information handling system; andprovide a management interrupt to the processor, the system management interrupt invoking an interrupt handler that reads the second indication from the memory; wherein the POST is operable to receive the input and to continue execution based upon the input.
