A computer's Basic Input-Output System (BIOS) is embedded software on a motherboard.
It is the first software your PC loads so that it can use things like CD drives, mice, and keyboards practically from the moment you turn it on.
First, head to the motherboard manufacturer’s website and find the Downloads or Support page for your specific model of motherboard.
You should see a list of available BIOS versions, along with any changes/bug fixes in each and the dates they were released. You’ll probably want the newest BIOS version unless you want an older one for a specific reason.
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.
Only when your BIOS has serious bugs, or newly built hardware such as CPU, RAM, hard drive, etc.
If you purchased a pre-built computer, head to the computer manufacturer’s website, look up the computer model, and look at its downloads page. Your BIOS download probably came in an archive — usually a file. You’ll find some sort of BIOS file — in the screenshot below, it’s the E7887IMS.140 file.
The archive should also contain a README file that will walk you through updating to the new BIOS.
Due to the size limitation of a 2.88MB floppy disk, you can only use a BIOS file and flashtool whose total file size is max ~2.7MB!
