In a method of integrating image and release note of BIOS, a memory space such as flash ROM used for storing machine codes of the BIOS is planned at least one independent block with a specific length, and each block is used for storing a release note of the BIOS. All release notes of the BIOS are compiled into at least one independent binary module, and the binary module is compressed according to actual requirements. In the process of building the BIOS, the compressed binary module is placed in the image of the BIOS, and the image of the BIOS is written into each block. When a setup utility of the BIOS is executed, all release notes of the BIOS can be displayed through an output device, so that a user can select and search a related item of each release note through an input device such as a keyboard.
