BIOS archive for a board identified as PR111, version A02, compressed in a 478 KB rar. Neither the brand nor the chipset appears in the name, so identification must come from the PCB markings. The A-style revision number is how some vendors, including Dell, mark BIOS releases, but the source is not confirmed here. Extract the image and program it with a CH341A or similar tool for recovery. Read and save the original chip contents first and verify the image matches the flash chip size.
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 @Laptopdesktopbios. Enginerys does not host this file.
