You then restart your computer and boot from the USB drive.In the minimal DOS environment that appears after the reboot, you run the appropriate command—often something like BIOS3245.bin—and the tool flashes the new version of the BIOS onto the firmware.The DOS-based flashing tool is often provided in the BIOS archive you download from the manufacturer’s website, although you may have to download it separately. In the past, this process was performed with bootable floppy disks and CDs.We recommend a USB drive because it’s probably be the easiest method on modern hardware.On Windows 7, 8, or 10, hit Windows R, type “msinfo32” into the Run box, and then hit Enter.The BIOS version number is displayed on the System Summary pane. Different motherboards use different utilities and procedures, so there’s no one-size-fits-all set of instructions here.The archive should also contain a README file that will walk you through updating to the new BIOS.You should check out this file for instructions that apply specifically to your hardware, but we’ll try to cover the basics that work across all hardware here.
That’s it—after you run the BIOS-flashing utility, reboot your computer and the new BIOS or UEFI firmware version loads.
However, you’ll perform the same basic process on all motherboards.
