As as computer user, you’ve probably heard of the BIOS by now, which stands for Basic Input/Output System. It’s that blue DOS-like screen that pops up if you press F8 or F2 while the computer is starting. The BIOS is the “firmware” for your computer. It’s code that is stored on a chip attached to your motherboard and is the first code that is run when your computer starts.
So what exactly does the BIOS do and do you need to update it? In this article, that’s what I am going to try and answer. Depending on who you talk to, you’ll quickly find that there is no one answer. Lots of people feel updating the BIOS is not necessary unless there’s a specific reason while others feel updating to the latest version is always a good idea. I’ll try to list out the pros and cons of both schools of thought. Feel free to let us know what you think in the comments.
What is the BIOS?
The main purpose of the BIOS is to check all the hardware components attached to the computer and then to load the software on a boot device (hard disk or CD/DVD). This first step is called a power-on self-test.
The BIOS will check for all hardware components like hard disk drives, CPUs, RAM, graphics cards, keyboards, mice, optical disk drives, and other hardware.
So what else can you do with the BIOS? Mainly, you can use it to configure the hardware on your computer. You can modify settings for hard drives, RAM chips, the CPU and other hardware. You can disable components like USB ports, optical drives, etc. You can change the system clock and manage the power settings from the BIOS also.
One of the main things you can do is setup the main and secondary boot devices. For example, you can change the order of the boot devices so that you can boot from CD/DVD first, then to USB, then to a hard drive, etc.
What does a BIOS Update Include?
If you see there is an update for your BIOS, either through Windows or by visiting the PC manufacturers website, you can usually download an executable program that will perform the update for you. Occasionally, you have to update the BIOS by other methods like using a CD or DVD, but that’s more rare now.
So what does a BIOS update usually include? Here are some of the possible reasons for an updated BIOS:
1. Bug fixes. The BIOS is just code and code is never perfect. An update may include fixes that help the software work better on your machine.
2. Compatibility. An updated BIOS may also include support for newer devices, newer features or newer standards.
3. Performance – There are times where an update include hardware tweaks that can speed up boot time.
The benefits are greater if the computer is older. If you have a machine that is 5 years old and the BIOS has never been updated, the latest version of the BIOS probably has a lot of update and fixes.
Do you need to Update the BIOS?
Now for the real question: do you need to upgrade your BIOS to the latest version? I personally feel that you should only update your BIOS if you’re currently having a problem. If you system is running smoothly and everything is working, why take a risk and possible corrupt your BIOS and end up with a dead machine.Also, I always check the BIOS change log to see what the latest version of the BIOS has to offer. For example, here’s a change lot for a set of Toshiba computers:
As you can see, the latest version of this BIOS adds support for certain keyboards, support for Celeron and Core i3 processors, improves on some settings for SSD drives, etc. Now if you are having an issue where your computer resumes from sleep or hibernate and takes a long time while using an SSD, that might be fixed with this update, according to the change log. That’s definitely a worthy reason to update the BIOS.
However, if you’re not using an SSD, don’t care about the Brazilian keyboard, don’t have a Celeron or Core i3 processor and don’t plan on changing your processor, etc, etc then the update is probably not necessary. I’ve always felt that a newer version of something is not always better. I’ve run into problems before updating drivers to the latest version and then having to roll back because the new driver was actually causing problems that the older driver never did.
Even though the process to update the BIOS is not very complicated, especially with newer computers, it’s still should only be done if you really need it. Don’t fix it if it’s not broken! If you really are not sure whether you need to upgrade or not, you can try to create a backup of your BIOS and then perform the upgrade.
Check out the link above, which walks you through the process of backing up your BIOS depending on the BIOS company. There are a couple of major ones like American Megatrends, AMI, Award, or Phoenix. Each company has their own tools for making backups of the BIOS.
