The BIOS (Basic Input/Output System) is critical firmware embedded on a small memory chip on the motherboard. For the Latitude 3420, official updates are typically distributed as .exe files from the Dell Support site . However, a "patched bin file" is a raw binary dump of this firmware that has been modified using third-party tools to remove specific lock bits.
