What is a BIOS Jumper?

Jumper is a plastic piece inside with a metal connection and is used to connect two pins in electronic components. Jumpers play the role of a connector. In the computer world, there are several types of jumpers, the most important of which are BIOS jumpers, motherboard jumpers, and hard jumpers, each of which has its function.

What is Jumper?

The jumper is a piece of plastic inside which has an electrically conductive body. Pacing the jumper on the special pins establishes the connection between the pins; removing it, the links are lost. One of the advantages of the jumper is that it shrinks when exposed to heat, and as a result, as the temperature rises, the connection between the pins becomes more stable. For this reason, jumpers are used in parts that may work in hot environments.

The jumpers somehow implement some functionality on the parts with this connection. Any piece with a jumper location is considered an optional piece that performs a particular task when the jumper is present and performs another job when the jumper is removed.

What is Jumper, and what do Hard Jumper and BIOS Jumper do?

The jumper is most commonly used in computer circuits. Jumpers can somehow send their data when connecting and not connecting; For example, when jumpers and pins are connected, the binary number 1 is shipped, and when not connected, the binary number 0 is shipped. Each of these numbers will have its interpretation in computer processing.

What is a bios jumper?

The BIOS jumper stores the information in the computer’s BIOS. You can change this information by entering the BIOS section of your computer. When exiting the BIOS environment, these changes are saved in the BIOS memory, and the new changes are applied the next time the computer is turned on. Suppose the changes are problematic for the computer or even the BIOS program. In that case, you can restore the BIOS program settings to the factory and default settings by placing a jumper or removing it from the motherboard (a special place for the BIOS near the BIOS battery). This jumper is used in all old and new motherboards.

 

BIOS jumper can be called one of the most used parts placed on motherboards, which can solve BIOS problems in many cases. To clear the connection established in the BIOS and somehow reset the CMOS and return to the initial BIOS settings; you can do this by removing the BIOS jumper. Jumper BIOS can even erase the passwords placed on the BIOS system.

What is a jumper on a motherboard?

Motherboards may have several jumpers on them. The most famous jumper on the motherboard is the BIOS jumper. There are also several jumpers on the motherboard, each doing a specific job. The most famous jumper after the BIOS jumper is the sound card jumper. You can enable or disable the motherboard sound card by removing or placing this jumper on the motherboard on the special pins related to the sound card.

 

There are other jumpers on the motherboard. A jumper in a motherboard can sometimes be responsible for sending a particular bit. In particular motherboards and server motherboards, jumpers can activate or deactivate a series of unique settings. For example, placing a specific sequence of jumpers on the server motherboard can enable or disable the ability to use a piece of hardware such as an internal network card.

What is a hard disk jumper?

In the series of IDE hard drives, to determine which hard drive is the primary hard drive and which Windows is installed on it, and which hard drive is the secondary hard drive and should be used after the main hard drive, they used the jumper hard drive feature. These jumpers are no longer used in today’s hard drives, and their settings are placed on the intelligent board of hard drives and motherboards. Hard disk jumpers are still used in certain types of hard disks. These jumpers can implement and apply specific settings on hard drives. The most crucial setting applied by the hard drive jumper is the master or slave mode, which is used when two hard disks are inserted.

 

 

You can activate different sections and modes of the hard disk by placing the jumper on the pins on the back of the hard disk in a specific way. The hard drive jumper was heavily used in the old IDE hard drives. With the advent of SATA hard drives and NVMe hard drives, jumpers are functional in these hard drives, and their related settings are made in the BIOS of motherboards.

 

As announced, Jumpers play an essential role in computer components and continue to play an active and colorful presence in these hardware components. You can activate or deactivate a unique feature on your motherboards or even hard disks by changing the jumpers connection location. Of course, you should remember that if the jumpers are manipulated by mistake, The hardware part does not work correctly or even in the worst case it gets damaged. So, before you want to change the hard jumper or the jumper on the motherboard, make sure how they work and their activities according to the manual.

FAQ:

Is there a hard jumper in the SATA hard drive?

No, in the SATA hard drive, there is no news about the hard reset jumper, and the enslaver or enslaved person settings of the hard drives have been transferred to the motherboard BIOS. There are jumper hard drives on old IDE and specific hard drives.

Do you have to pull out the BIOS jumper to reset the BIOS?

You can reset it by moving the BIOS jumper, and if you don’t know where your jumper is, you can do it by removing the BIOS battery from the motherboard body (a flat battery that looks like a small coin). The safest way to reset the BIOS is to use the BIOS jumper.

Is it possible to burn the motherboard by changing the jumper on the motherboard?

No, Changing the jumper on the motherboard does not allow them to burn; of course, you should be careful that each jumper on the motherboard does a specific job, and it is possible that by changing the location of the jumper on the motherboard, a piece of your hardware will be removed from the circuit and disabled.

Is there a possibility of electric shock if you touch the jumpers?

The electricity available in computers is generally 12 volts and 24 volts. It is better not to change the jumpers when the computer is on. Jumpers can be changed when the computer is off. To be more sure, it is better to disconnect the power cable from the computer’s power supply.
