BIOS update file used to "flash" the BIOS to ASUS computers running Windows; contains settings and instructions for updating the BIOS on an ASUS motherboard.
BIOS stands for "Basic Input/Output System" and is a type of firmware used by a computer's microprocessor to boot the computer system when it is turned on. It is also used to manage the data flow between a computer's operating system and any attached devices.
NOTE: To update the BIOS on your computer, download the CAP file from the ASUS website and copy it to a USB key (formatted to FAT or FAT 32). Then, connect it to the appropriate ASUS machine, and use the EZ Flash utility (built into the BIOS firmware) to load the update.
