It was traditionally the case that resetting bios was simply pulling the battery because that was the only thing that held it in memory. This isn't a hack -
- this is the official method of the older era which required power for persisted settings.
Even with Dell and the passwd jumper, that still required batteries to persist the settings up until relatively recently. We have a handful of Dell Optiplex 980s (circa 2010) which are now being decommissioned (after a particularly long and reliable service) and their CR2032 batteries are dying and they're losing settings if unplugged.
