Updating the bios averatec
It’s better to be safe than sorry, so we recommend using a BIOS-based flashing tool or booting to a minimal DOS environment to flash your BIOS.
At the prompt, type (or copy and paste) the following command, and then hit Enter: You can also find your BIOS’s version number in the System Information window.
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.
You probably shouldn’t update your BIOS, but sometimes you need to.
Here’s how to check what BIOS version your computer is using and flash that new BIOS version onto your motherboard as quickly and safely as possible. If your computer freezes, crashes, or loses power during the process, the BIOS or UEFI firmware may be corrupted.
