BIOS archive in RAR format for the S-TH310C-M4 motherboard, containing an 8 MB image according to the name. The model string points to an H310-based desktop board, and 8 MB matches a 64 Mbit SPI flash chip. Technicians use this kind of dump to revive a board stuck without display or post after firmware corruption, writing it with a CH341A or similar programmer. Check the model printed on the PCB, save the existing chip contents as a backup and make sure the chip is 8 MB before programming.
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.
