在这篇文章中，我们将讨论什么是BIOS 白名单(BIOS Whitelist)、它的用途以及如何删除它。简而言之，BIOS白名单本质上是批准在该计算机中使用的硬件列表——如果您尝试使用其他任何东西，计算机将不会检测到它。 OEM(OEMs)使用硬件的BIOS白名单，以便他们可以限制用户购买任何其他品牌。
BIOS 代表基本输入输出系统。它是计算机系统的一部分，在加载操作系统负载之前检查计算机。BIOS的一些重要功能是：
- 检查所有设备都连接到计算机。该列表包括鼠标、键盘、操纵杆等。
- 加载设备驱动程序并检查它们是否存在故障。计算机会给您一条错误消息，即任何驱动程序不可用。例如，如果未检测到键盘，则会显示“未找到键盘”。(Keyboard)这是在加载操作系统之前
- 它还管理RAM，直到操作系统接管
- 在测试引导设备（HDD或DVD或闪存(Flash)驱动器）的故障后，它将操作系统的基本部分加载到RAM中。从那里，操作系统接管。
什么是 BIOS 白名单
白名单通常是计算机上允许的程序、软件和系统文件的列表。如果是防火墙，您可能已经创建了可以访问Internet的程序列表。那就是防火墙白名单。BIOS 白名单(BIOS Whitelist)也适用于类似的线路。
如果您向计算机添加新硬件或更换损坏的旧硬件，计算机将首先检查BIOS白名单以查看是否允许使用该特定硬件（品牌、制造商或型号）。
因此，BIOS白名单本质上是批准在该计算机中使用的硬件列表。如果您尝试使用其他任何东西，计算机将无法检测到它。您可能会问为什么需要BIOS白名单。下一段将讨论BIOS白名单的使用。
BIOS白名单有什么用
BIOS白名单的预期用途是看到最终用户没有安装任何可能导致与计算机上其他硬件发生冲突的硬件。BIOS白名单是指在不与现有硬件冲突的情况下，可以在计算机上使用的所有硬件的列表。
但昨天就是这样。在我看来， BIOS(BIOS)白名单的真正目的是阻止购买任何其他型号和品牌的硬件部件。例如，如果您购买一台XYZ品牌的电脑，并想为其添加 Wi-Fi 网卡，您将只需要购买BIOS中列入白名单的那些。这几乎意味着品牌正在限制您的选择，以便您坚持使用与您拥有的计算机相同的品牌。
为什么用户不喜欢BIOS白名单
如上所述，并非所有计算机制造商都同意人们在其计算机上使用任何其他品牌的硬件。因此，他们以(Hence)BIOS 白名单(BIOS Whitelist)的名义实施限制。即使你有网卡等兼容的硬件，如果它不在BIOS白名单中，你也不能使用它。这就是人们不想要任何BIOS(BIOS)白名单的主要原因。
如果BIOS(BIOS)中没有白名单或者如果它被关闭，用户可以使用他们想要的任何硬件 - 与原始计算机一起使用。为了能够将任何硬件安装到品牌计算机中，您必须删除BIOS白名单。
如何删除 BIOS 白名单
因为现在包括惠普在内的很多品牌都声称已经取消了BIOS白名单，你应该可以通过升级你的BIOS来解决。请注意，您必须从计算机供应商的网站（如 HP、 Lenovo等）下载BIOS升级软件，例如Lenovo System Uptade Tool、 HP Support Assistant 等。
除非您知道二进制数学，否则没有其他方法可以删除BIOS白名单。(BIOS)您可能无法通过刷新 BIOS来删除(flashing the BIOS)BIOS白名单。例如，人们正在向联想(Lenovo)发送在线请愿书，要求他们删除BIOS 白名单(BIOS Whitelist)（如果有）。我了解 HP 不再创建BIOS白名单，因此您可以通过访问hp.com轻松升级BIOS。
What is a BIOS Whitelist? Explanation and removal.
In this post, we will discυss what a BIOS Whitelist is, what is its use, and how to remove it. In short, a BIOS whitelist is essentially a list of hardware approved for use in that computer – if you try to use anything else, the computer won’t detect it. OEMs use a BIOS whitelist for hardware so that they can restrict users from buying any other brand.
BIOS stands for Basic Input Output System. It is the part of computer system that checks the computer before loading the operating system loads. Some of the important functions of BIOS are:
- Checking what all devices are attached to the computer. That list includes a mouse, keyboard, joysticks, etc.
- Loading the device drivers and checking them for faults. The computer gives you an error message is any of the drivers is not available. For example, if the keyboard is not detected, it would say, “Keyboard Not Found”. This is before loading the operating system
- It also manages RAM until the operating system takes over
- After testing the boot device (HDD or DVD or Flash drive) for faults, it loads the elementary parts of OS into the RAM. From there, the operation system takes over.
What is BIOS Whitelist
A whitelist is generally a list of programs, software, and system files that are allowed on a computer. In case of a firewall, you might have already created a list of programs that can access the Internet. That is the firewall whitelist. BIOS Whitelist too works on similar lines.
If you add new hardware to your computer or replace old, damaged hardware, the computer will first check the BIOS whitelist to see if that particular hardware (brand, make, or model) is allowed.
Thus, BIOS whitelist is essentially a list of hardware approved for use in that computer. If you try to use anything else, the computer won’t detect it. You may ask why BIOS whitelist is required. The next paragraphs talk about of use of BIOS whitelist.
What is the use of BIOS whitelist
The intended use of BIOS whitelist is to see that the end users do not install any hardware that can cause conflicts with other hardware on the computer. The BIOS whitelist means a listing of what all hardware one can use on the computer without conflicting with existing hardware.
But that is so yesterday. The real purpose of BIOS whitelist, in my opinion, is to block hardware parts bought of any other model and brand. For example, if you buy a computer from XYZ brand, and want to add a Wi-Fi network card to it, you will have to buy only the ones whitelisted in BIOS. This pretty much means that brands are limiting your options so that you stick to the same brand as that of the computer you have.
Why users don’t like a BIOS whitelist
As discussed above, not all computer manufacturers are OK with people using any other brand of hardware on their computers. Hence, they enforce restrictions in the name of BIOS Whitelist. Even if you have compatible hardware such as a network card, you can’t use it if it is not listed in the BIOS whitelist. That is the main reason why people don’t want any BIOS whitelist.
If there is no whitelist in BIOS or if it turned off, users can use any hardware they want – with the original computer. To be able to install any hardware into a branded computer, you must remove the BIOS whitelist.
How to remove BIOS whitelist
Because now many brands, including HP, are claiming to have removed BIOS whitelist, you should be able to get around by upgrading your BIOS. Note that you have to download the BIOS upgrading software from the computer vendor’s websites like HP, Lenovo, etc. – e.g. Lenovo System Uptade Tool, HP Support Assistant, etc.
There is no other way to remove the BIOS whitelist unless you know binary mathematics. You may or may not be able to remove BIOS whitelist by flashing the BIOS. People are sending online petitions to Lenovo, for example, asking them to remove the BIOS Whitelist, if any. I understand that HP is no longer creating BIOS whitelist so you could easily upgrade the BIOS by visiting hp.com.
