The BIOS (Basic Input/Output System) on an ASUS motherboard stores all of the hardware configuration settings for the computer. The BIOS on your ASUS motherboard is also responsible for instructing the operating system on how to allocate resources for various computer components. To ensure compatibility with newer types of hardware, ASUS releases BIOS updates from time to time. If you need to correct compatibility issues or solve hardware conflicts, updating the BIOS can help. ASUS BIOS update programs use .BIN files to overwrite or flash the ROM chip. However, before you can update the BIOS chip, you must first decompress or extract the downloaded update file.
