When the number of times of restarting the server reaches the preset threshold and the BMC is still not activated, the BMC is determined to be abnormal. When the number of times of restarting the server has not yet reached preset threshold, the BIOS performs the action of restarting system, wherein preset threshold is confirmed by a variable self-defined inside the BIOS and may be set freely.
