BIOS .rar 14.6 MB Shared

Firmware archive for the MSI Z170A desktop motherboard, MSI board code MS-7977, an Intel Z170 chipset platform. MSI marks its desktop boards with MS-xxxx numbers printed on the PCB, and several Z170A variants share the same code, so check the exact model before flashing. The archive is about 14.6 MB, which suggests full-chip images or multiple files rather than a single dump. Use it to restore a damaged BIOS chip with a programmer or MSI recovery tools, and always keep a copy of the original contents.

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.
