BIOS update with service processor without serial peripheral interface (SPI) access

摘要

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.

主权项

1. A system, comprising:
a service processor (SP), comprising a processor, a non-volatile memory, a volatile memory and a system interface, wherein the non-volatile memory stores computer executable codes, and the codes are configured to, when executed at the processor,
receive a basic input/output system (BIOS) image from a remote management computer, and store the BIOS image in the volatile memory;receive, from a BIOS being executed at a central processing unit (CPU) of a host computer through the system interface, a request for the BIOS image stored in the volatile memory, wherein the request for the BIOS image is a first IPMI original equipment manufacturer (OEM) message generated by the BIOS being executed at the CPU of the host computer; andin response to the request for the BIOS image, send a copy of the BIOS image stored in the volatile memory to the host computer through the system interface such that the BIOS being executed at the CPU of the host computer receives the copy of the BIOS image and replaces a current BIOS image stored in a BIOS chip of the host computer with the copy of the BIOS image.
