BIOS archive for a board identified as S-TJ31G-Y A170B revision 4.2, supplied as a 2.36 MB RAR. The name does not state the brand, chipset or flash type, so identify the SPI chip on the board and compare its capacity with the image before writing. Dumps like this are used to restore boards that fail to POST after a bad update. Use a CH341A or similar programmer, back up the original chip first, and confirm the PCB marking and revision 4.2 match exactly.
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.
