BIOS package for the Walton WP156US laptop, with a 6-77-W950JU00-D02B code in the name, delivered as a 3.99 MB ZIP. The 6-77 W950 style resembles Clevo board and part numbering, suggesting a Clevo-based barebone rebranded by Walton, though verify on the PCB. A technician uses this image to recover a dead or corrupted board by reprogramming the SPI flash with a programmer. Check the marking on the motherboard, back up the original chip data, and confirm the image matches the flash size.
