Small firmware archive for the R3-131T with the board number 14299-1, which follows Wistron's five-digit numbering pattern. At only 56.7 KB it is too small to be a full BIOS image, so it more likely holds an EC firmware or a partial region. Check the contents before flashing and do not write it to the main SPI chip as a complete BIOS. Match the 14299-1 marking on the PCB and read and keep the original chip contents before you change anything on the board.
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 @afsbiosfree. Enginerys does not host this file.
