Firmware for the MSI Pro 22ET 7M-059RU all-in-one, mainboard MS-AC171 version 1.0, provided as a 5.26 MB ZIP archive. MSI uses MS-xxxx codes for its own boards, so the number identifies the internal mainboard of this unit. The image helps recover a system that fails to start after a bad update by writing the SPI chip with an external programmer. Confirm that the PCB reads MS-AC171 at version 1.0, dump the existing chip as a backup, and verify the file size matches its capacity.
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.
