TW557438B - Device for maintaining contents of basic input output system (BIOS) chip and method thereof - Google Patents

Abstract

The present invention relates to a device for maintaining contents of basic input output system (BIOS) chip and a method thereof. Particularly the present invention is a technology to be applied for detecting and updating contents of BIOS chip when power-on is inaccessible due to BIOS damage. In accordance with the technology, the maintaining device stores all the data required for updating the BIOS chip and, when computer power-on is inaccessible, can be connected with the computer to form a data transmission path. By means of the data transmission path, not only all the power, address, and data buses required by the computer can be provided but also, at the same time, the updated contents of the BIOS chip can be obtained and debugged. When any error or overtime is found in the contents of the BIOS chip, updating will be carried out on the BIOS chip based on the updated data. Thus, research and development efficiency can be improved and fabrication cost can be lowered.
