AMIUCP.exe is a small 424 KB Windows executable whose name points to an AMI utility; the name gives no version, board or brand. Tools from American Megatrends with this kind of name are generally used to view or change configuration strings and settings embedded inside AMI Aptio BIOS images before they are flashed. Treat it as a workshop utility rather than firmware. Run it on a copy of the BIOS file, never on your only backup, and scan unknown executables before launching them on a bench PC.
