Abstract
Certain aspects direct to basic input/output system (BIOS) failover update with a service processor (SP). In certain embodiments, the system includes a host computer and a SP. A CPU of the host computer loads and executes a current BIOS image stored in a BIOS chip to a memory as a BIOS instance. The SP receives, from the executed BIOS instance at the host computer, a BIOS image as a failover backup image, and stores the failover backup image in the volatile memory of the SP. When an error occurs at the host computer, the executed BIOS instance sends a request for the failover backup image to the SP. In response, the SP sends a copy of the failover backup image to the host computer such that the executed BIOS instance may replace the current BIOS image stored in the BIOS chip with the copy of the failover backup image.
