Method and apparatus of detecting fault for external device

An apparatus of detecting a fault for an external device, the external device being in communication connection with a Basic Input Output System (BIOS), wherein the apparatus comprises:

• an execution unit, configured to execute a preset operation according to target information, wherein the execution unit is configured to execute the preset operation according to the target information by following steps:
• in a case where the target information comprises first error information, executing the preset operation of injecting the first error information into the external device, and in a case where the target information comprises first register data, executing the preset operation of sending the first register data to the BIOS, wherein the first register data is register data generated by a register, which simulates the external device, in response to second error information;
• a first acquisition unit, configured to acquire a first log, and/or, a second log reported by the BIOS, wherein the first log is a log obtained by the BIOS parsing second register data, the second register data is register data generated by the register in response to the first error information, and the second log is a log obtained by the BIOS parsing the first register data;
• and
• a first determination unit, configured to determine a running state of the external device according to the first log and standard register data corresponding to the first error information, and/or determine a running state of the BIOS according to the second log and a standard log corresponding to the first register data, wherein the running state is a fault state or a normal state.
