Abstract
Certain aspects direct to BIOS update with a service processor (SP) without access through a serial peripheral interface (SPI). In certain embodiments, the system includes a SP, which includes a processor, a non-volatile memory, a volatile memory and a system interface. The SP receives a BIOS image from a remote management computer, and stores the BIOS image in the volatile memory. When the SP receives, from a BIOS executed at a central processing unit (CPU) of a host computer through the system interface, a request for the BIOS image, the SP sends a copy of the BIOS image in response to the request for the BIOS image to the host computer through the system interface such that the BIOS executed at the CPU of the host computer replaces a current BIOS image stored in a BIOS chip with the copy of the BIOS image.
