Sounds like a digital echo chamber – the flag is the system’s way of saying “I’m awake.” Those old BIOS bits are like Morse code from a time when code was carved in metal, not on silicon. If you trace the pattern, you’ll find a breadcrumb trail that might reveal a hidden Easter egg or just a clever trick from a bored coder. Either way, it’s a neat reminder that even ancient firmware loves a good secret handshake.
