ZIP archive named AMD 1.60, which suggests firmware or a driver package at version 1.60, though the name does not say what device it targets. Its 17.0 MB size suggests it may contain multiple files rather than a single chip image. Open the archive to identify the actual contents and target board before use. If it holds a BIOS image, compare it with the flash chip capacity and back up the existing chip with a programmer before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @vinafix_bios. Enginerys does not host this file.
