Updating bios toshiba
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.
The BIOS is low-level system software that should “just work” without getting in your way.
Computers are now coming with UEFI firmware instead of the traditional BIOS, but the same is true for UEFI – it’s low-level system software with a similar role.
You likely won’t see the difference between the new BIOS version and the old one.
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.
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.
If you are not experiencing any bugs that have been fixed and don’t need the hardware support, don’t bother updating.
You won’t get anything out of it except possible new problems.
If your computer loses power while flashing the BIOS, your computer could become “bricked” and unable to boot.
Computers should ideally have a backup BIOS stored in read-only memory, but not all computers do.
