Jumpers are electrical pins used on motherboards and some devices, such as hard drives, to enable, regulate, or disable certain functions of a system that are not accessible through software.  See how they can be utilized for your potential benefit.

What are jumpers for?

On older motherboards, there were too many jumpers. As the electrical key, its function was to determine the operation of the various functions of the hub. It was possible, for example, to use a jumper or bridge to limit the power of the processor and consequently reduce its speed and heating system.

Other jumpers, also known as jumpers that restore BIOS information work to factory settings. Those responsible for determining the date and time and the internal battery control scheme of the system were still present.

Now a days it’s difficult to select Motherboard. But when it comes purity and details no one can write better than Blogs Hour. So, once again we have discussed a detailed buying guide of 5 best motherboard for ryzen 9 3900x

The older boards had a larger set of jumpers that allowed wider control over the operation of all hardware that established a link to the motherboard. From meal speeds to expansion cards.

If your computer is a few years old, chances are it still has clusters of jumpers. Be aware that many of these can cause changes in the critical operation of the machine.

Do they still Exist?

Jumpers are rare on new boards (some still have some, mainly LEDs and cabinet buttons used to adjust the behavior). With the development of technology, especially firmware and BIOS, jumpers have lost their usefulness, as it has become possible to make all adjustments through software.

Where are they found?

Today, jumpers are deviating from the right when it comes to plates. But standard IDE hard drives still have keys in their set. In HD, jumpers are used to determine the behavior and classification of the hard drive before the system.

For example, when a jumper is removed and replaced, it determines that the hard disk behaves like a slave in the system, meaning it is not charged to start and boot the system. ۔ Some disks have jumpers that determine the reading speed and can limit the storage space on the disk.

Jumpers are also found on logic boards with specific functions, such as those used in Arduino applications. It should be noted that the Raspberry Pi also brings bridges to its plates.

Update your BIOS

ASUS has delivered major BIOS refreshes for a significant number of its new motherboards with an extremely straightforward reason, to make similarity with Windows 11 simpler.  Windows 11 is ready. We should perceive what they have done and which sheets are viable.

One of the biggest problems users face when upgrading to Windows 11 is the need for TPM 2.0 support. The point is, motherboard manufacturers do not have to enter the name “TPM” directly into their BIOS, but sometimes have to go for alternatives.

For example, depending on the processor used, you may see names like “PTT” or “PSP fTPM”. So Microsoft has urged motherboard manufacturers to make it easier to support Windows 11. How? OK, enable this feature on new motherboards by default.

In response, ASUS has released a BIOS update for its motherboards that has TPM 2.0 fully enabled by default, making the computer compatible with Windows 11. As we said, almost all brand models are compatible, and in particular they have released BIOS boards with the following chip sets:

As we can see, in recent years all chip sets from both Intel and AMD (since 2017, almost approximately) have been covered by this update, although all motherboards currently in use have their BIOS not available. The full list, along with download links, can be consulted on the company’s official website.

If you notice that your motherboard is not compatible, the process for activating TPM is as follows, always inside the BIOS (press delete when you see the ASUS or ROG logo on the screen):

On Intel Processors, go to the Advanced tab, and find the PCH-FW configuration. There, enable PTT by activating it.

On AMD Processors, go to the Advanced tab, and find the AMD fPTM configuration. There, leave “TPM Device Selection” as firmware TPM, and not as discrete PTM.

Then press F10 to save the changes.

If your motherboard is ASUS, it needs to be updated, keeping in mind that Windows 11 is in the corner. It has only 3 months left to start. After making the changes, check out our article to see if your computer is compatible with Windows 11, and be able to verify that you’ve implemented everything correctly.
