In this post, we will discuss what BIOS whitelist , what it is used for and how to dispose of it. In short, a BIOS whitelist is essentially a list of hardware approved for use on that computer; If you try to use something else, your computer will not detect it. OEMs use a hardware BIOS whitelist so that they can restrict users from buying any other brand.
BIOS stands for Basic Input Output System. It is the part of the computer system that the computer checks before loading the operating system. Some of the important functions of the BIOS are:
Check all devices connected to the computer. This list includes a mouse, keyboard, joysticks, etc.
Load the device drivers and check for errors. Your computer sends you an error message if any of the drivers are not available. For example, if the keyboard is not detected, it will say «Keyboard not found». This happens before the operating system loads
It also manages RAM until the operating system takes control
After testing the boot device (HDD or DVD or Flash drive) for malfunctions, it loads the basic parts of the operating system into RAM. From there, the operating system takes control.
What is the BIOS whitelist
A whitelist is generally a list of programs, software, and system files that are allowed on a computer. In the case of a firewall, you may have already created a list of programs that can access the Internet. This is the white list of firewalls. The BIOS whitelist works on similar lines.
If you add new hardware to your computer or replace old and damaged hardware, your computer will first check the BIOS whitelist to see if that hardware (brand, make, or model) is allowed.
Therefore, the BIOS whitelist is essentially a list of hardware approved for use on that computer. If you try to use something else, your computer will not detect it. You may be wondering why a BIOS whitelist is needed. The following paragraphs talk about using the BIOS whitelist.
What is the BIOS whitelist for
The intentional use of the BIOS whitelist is to see that end users do not install any hardware that may cause conflicts with other hardware on the computer. BIOS whitelist means a list of all hardware components that can be used on your computer without conflicting with existing hardware.
But that was yesterday. In my opinion, the real purpose of the BIOS whitelist is to block hardware purchased from any other brand and model. For example, if you buy an XYZ branded computer and want to add a Wi-Fi network card to it, you only need to buy those that are listed in white in the BIOS. This means that brands limit your options so that you stay on the same brand as the computer you own.
Why users don’t like a whitelist BIOS
As mentioned above, not all computer manufacturers agree that people use any other brand of hardware in their computers. Therefore, they impose restrictions on behalf of the BIOS whitelist. Even if you support hardware, such as a network card, you cannot use it unless it is listed in white in the BIOS. This is the main reason why people don’t want any BIOS whitelist.
If there is no whitelist in the BIOS or if it is disabled, users can use any hardware they want with the original equipment. To install any hardware on a branded computer, you must remove the BIOS whitelist.
How to remove the BIOS whitelist
Because many brands, including HP, claim to have removed the BIOS whitelist, you should be able to get the BIOS updated. Keep in mind that you need to download the BIOS update software from the websites of the computer vendor such as HP, Lenovo, etc. – p. For example, Lenovo System Uptade tool, HP support assistant, etc.
There is no other way to remove the BIOS whitelist unless you know binary math. You may or may not be able to clear the BIOS whitelist by flashing the BIOS. People send online requests to Lenovo, for example, asking them to remove the BIOS whitelist, if any. I understand that HP no longer whitelists the BIOS, so I could easily update the BIOS by visiting hp.com.
