I replaced the BIOS chip and flashed it with the file you provided. The laptop powers on and I can see the display backlight, but there’s no logo or image. The indicator lights flash 3 red and 5 white repeatedly.
When I reflash the original BIOS file, the screen only shows a white–blue–red–green color pattern.
