Tested working BIOS for the J&W H61M-D3 motherboard, supplied as a 2.48 MB RAR archive. The name states the board model and the tested status but no BIOS version or flash size. Use it to rewrite the SPI flash when the board shows no display, loops on power-up or stopped after a failed flash. Always dump and store the existing chip contents first, compare the model silkscreened on the PCB, and make sure the extracted image size equals the flash chip capacity.
