Abstract

The embodiment of the invention discloses a method and a system for out-of-band upgrading. The method for out-of-band upgrading comprises the following steps: switching a firmware chip onto a firmware upgrading controller through an isolation switching circuit; and upgrading the firmware chip through the firmware upgrading controller. The out-of-band upgrading system comprises a south bridge chip, the firmware chip, the isolation switching circuit and the firmware upgrading controller, wherein the isolation switching circuit is used for switching the firmware chip onto the firmware upgrading controller; and the firmware upgrading controller is used for upgrading the firmware chip. The embodiment of the invention provides quick out-of-band upgrading channel for the firmware chip, and can complete upgrading of the firmware chip without entering an operation system, facilitate upgrading of the firmware chip, and improve the reliability of the firmware chip.

Description

technical field [0001] The invention relates to hardware upgrading technology, in particular to an out-of-band upgrading method and system. Background technique [0002] The basic input / output system (Basic Input / Output System; hereinafter referred to as BIOS) is a set of programs solidified into a read-only memory (Read-Only Memory; hereinafter referred to as ROM) chip on the computer motherboard. The hub between the program and the hardware device, which stores the most important basic input and output programs of the computer, system setting information, power-on self-test program and system startup bootloader program, provides the computer with the lowest-level and most direct hardware setting and control . [0003] Since the BIOS chip currently on the market usually uses Flash ROM, the BIOS can be upgraded through a specific writing program. By upgrading the BIOS, new functions can be obtained free of charge, such as a central processing unit (Central Processing Unit) ...
