This wasn&#x27;t removing firmware as in the actual boot code for the motherboard. It was just clearing the list of what drives to attempt to load an OS from. That list is explicitly intended to be accessible to and modifiable by operating systems, to provide a better user experience than the old method of the user having to manually change BIOS settings.<p>The standard practice for PCs has always been that firmware configuration settings can be cleared (through a jumper or by pulling the battery) to reset the system to its factory state, forcing it to fall back to its conservative and safe defaults. Some systems have apparently forgotten to have defaults. Their firmware is already broken and afflicted with a major bug even if you avoid triggering it in this particular manner.
