BIOS image for the MSI MS-16Y1 board, revision 2.0, with A15HC included in the name as an additional model or version tag, packed in a 1.93 MB RAR file. MSI uses its own MS-xxxx numbering, printed on the motherboard, and that code should match the one here before flashing. The dump is meant for restoring firmware on the SPI flash with an external programmer when a notebook will not post or is stuck after an update. Save the original chip contents first and verify the image size suits the flash chip.
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.
