Your computer's BIOS (Basic Input/Output System) is the first software your PC loads. It sets the stage for your operating system, so to speak, by finding all your PC's various hardware components and letting the operating system know it can use them.
As with any software, your computer or motherboard manufacturer periodically updates the BIOS to fix bugs, add compatibility with new devices, improve caching functions, and make several other hardware tweaks that can speed up your boot time and fix annoying issues. These updates are available at the manufacturer's site. But if you make a mistake in the update process, you risk rendering your PC unbootable. Here's how to make sure your BIOS update goes without a hitch.
