American Megatrends Inc, or AMI, is a company that develops BIOS (Basic Input/Output System) programs for motherboard manufacturers such as ASUS and MSI. AMI BIOS allows you to configure hardware and software settings on a computer during startup. However, most motherboard manufacturers lock some of the BIOS settings because they are usually dangerous to modify. If you are an advanced user, you can unhide the locked settings by using certain key combinations.
Turn on the computer.
