Zipped dump of about 940 KB for the ASUS N6506 motherboard, with GN21-X4-A1 in the name, which is an NVIDIA GPU code name and hints at the graphics variant fitted. Because the size is under 1 MB, the contents may be an EC or partial image rather than a full BIOS, so inspect the archive. It serves as a reference when reprogramming a chip with a programmer. Check the board revision silkscreen, back up the original chip, and confirm the image matches the flash capacity.
