![]() Computers should ideally have a backup BIOS stored in read-only memory, but not all computers do. If your computer loses power while flashing the BIOS, your computer could become “ bricked” and unable to boot. Each manufacturer has its own instructions for flashing a BIOS. You will often want to flash your computer from DOS (yes, DOS-you may have to create a bootable USB drive with DOS on it and restart into that environment), as problems could occur when flashing from Windows. In some cases, you may even experience new bugs with a new version of the BIOS, as the BIOS that came with your computer may have gone through more testing.įlashing a BIOS isn’t as easy as installing a normal software update. You likely won’t see the difference between the new BIOS version and the old one. If your computer is working properly, you probably shouldn’t update your BIOS. ![]() BIOS updates typically have very short change logs-they may fix a bug with an obscure piece of hardware or add support for a new model of CPU. Why You Probably Shouldn’t Update Your BIOSīIOS updates aren’t big software upgrades that add new features, security patches, or performance improvements. BIOSes are computer-specific (or motherboard-specific), so you will need the BIOS for your exact model of computer (or motherboard) to update your computer’s BIOS.
