The BIOS, much like the Windows Registry, is a part of the system we rarely configure. It seems fairly technical, and with all the warnings doing the rounds, it feels like something best left untouched. For a long time, I didn’t change much in the BIOS, except for capping the battery charge level and a few other simple settings. But as I dug more into it, I found out that there are a bunch of other settings, which, if optimized, could boost the PC’s performance. And these are not those risky overclocking tweaks we have all heard about. These are simple changes anyone can make, usually without introducing instability.
