You must have seen the CSM option inside BIOS whenever you entered it knowingly or unknowingly.
In this article, we are going to explain everything you need to know about what is CSM option in BIOS, why it is present there, and what is its purpose.
Also, users have been wondering if the CSM option in BIOS should be enabled or disabled and what will happen if they enable or disable it.
So we will explain everything to you down below which means that you need to read each and everything carefully.
What is CSM support in BIOS?
CSM stands for Compatibility Support Module and it is a component of the UEFI that allows legacy BIOS compatibility.
In other words, it allows the legacy operating systems to support UEFI even if they didn’t have that support at launch.
It is similar to the cross-compatibility modules that we have seen in PlayStation and Xbox consoles so that they can support older models as well.
Should CSM be enabled or disabled in your BIOS?
Now that you know what CSM stands for and what it is meant to do, you must be wondering if you should enable it or disable it inside your BIOS.
First of all, we must mention that you should not tinker with the default settings on your PC’s BIOS.
If your CSM support is enabled by default, keep it enabled and if it is disabled then you don’t need to enable it.
Apart from that, CSM support is needed for legacy operating systems.
For example, if you are running Windows 10 then it already supports UEFI which means you don’t need to enable CSM on PCs running Windows 10.
However, if your PC is running Windows XP or other legacy operating systems then you need to enable CSM in order for it to support UEFI.
