BIOS binary for a Lenovo IdeaCentre 720-18ASU AMD desktop, with O38KT29A appearing as the firmware identifier and AM4MH as the board name. The 4.81 MB ZIP holds a BIN file meant for direct SPI programming. The AM4 tag points to AMD's socket AM4 platform. Technicians use such images to recover a dead or bricked board with an external programmer. Back up the existing chip before writing, and check that the image size matches the flash capacity, since a mismatched file will not fit.
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 @biosarchive. Enginerys does not host this file.
