Apparatus and method for recovering an information handling system from a non-operational state
View Patent ↗A method recovers an information handling system (IHS) from a non-operational state. The method includes determining if the non-operational state of the IHS has occurred. In response to determining that the non-operational state of the IHS has occurred, a basic input-output (BIOS) recovery device is identified as being coupled to an embedded controller. In response to identifying that the BIOS recovery device is coupled to the embedded controller, an IHS type is transmitted to the BIOS recovery device. The BIOS recovery device is signaled to determine if the BIOS recovery device contains a BIOS payload corresponding to the IHS type. In response to determining that the BIOS recovery device contains the BIOS payload corresponding to the IHS type, the BIOS recovery device is triggered to transmit the BIOS payload to the embedded controller. The IHS is triggered to restart using the new BIOS payload.
