Abstract
The method includes following steps. New patch file is copied from external to patch file buffer part in main control board. Based on types of new patch file, loading module loads new patch file to patch areas of all the typed single board, and the patch parameters are written to patch parameter areas of FLASH of all the typed single board as well as FLASH of main control board. When new inserted single board is started, the typed patch file in main control board is copied to the single board through handshaking between the single board and BIOS of main control board. Thus, the single board obtains patch parameters. If the patch parameters obtained is the same as the patch parameters stored in the single board, then loading module in the single board loads the patch file in FLASH of the single board to the patch area of the single board. The invention possesses features of small message coupling degree between loading module and other modules, and simple loading procedure.
