BIOS for a TG-HM65 motherboard based on the Intel HM65 chipset with an Intel CPU, sized for a 4 MB flash chip, distributed in a RAR archive of about 4.9 MB. Such dumps are used to reprogram the SPI flash with a programmer on boards that will not power on properly or display nothing. A 4 MB image requires a 32 Mbit chip, so confirm the fitted part matches. Compare the board markings with the name, and read and save the original chip before erasing or writing.
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.
