The method of the computer board jumper setting is detailed

First, understand the type of jumper

Up to now, the jumper has developed to three generations, namely the key cap type jumper, dip type jumper, soft jumper.

1. Key Cap type jumper

The key cap jumper is made up of two parts: the base part and the key cap part. The former is two or three disconnected needles up upright, and the adjacent two pins determine a switch function. The operation of the jumper only has short and disconnected two types. When using a jumper, that is, a short jumper, will be able to allow two of the needle to connect the key cap to the two of them, so that two needles are connected to the function of the jumper should have. Otherwise, you can put the key cap on only one needle, and the other tube of the key cap is empty. Thus, because the two needles are not connected, the corresponding function is forbidden, and the key cap will not be lost. Because the key cap only means the connection, so there is no problem of inserting the counter. The key cap type jumper is divided into two stitches and three needles, two stitches are more convenient to use, the application is more extensive, short connection means to have a function, disconnect means to prohibit a function; The three needles are more complex, such as Needles 1, 2, 3, then short pin 1, 2 represents a function, and short 2, 3 represents another function.

2.DIp type jumper

Dip type jumper is also called dip combination switch, dip switch can not only use a button switch to express a function, but also can combine several dip switches to express more states, more functions. A dip switch can be flip on both sides of the button to determine the two switch states, one side of the open (on), the other side of the off. And for the combination of the use of state, how many dip switches can represent the number of power of 2 of the state, there are how many values can be selected, so enter the DIP switch must be compared to the table in the manual set the value, otherwise you do not know so much state.

3. Soft jumper

Soft jumper does not have a real jumper, that is, CPU-related settings no longer use the hardware jumper, but through the Cmossetup program to set up, do not need to open the chassis, very convenient.

In the computer accessories, the motherboard, hard disk, optical drive, sound card are existing jumpers, to the motherboard jumper most complex, the hard drive second.

Second, the motherboard jumper settings

The jumpers on the motherboard generally include CPU setup jumper, CMOS clear jumper, bios prohibit write jumper, etc. Among them, the CPU to set the most complex jumper, if the motherboard is older, you must set the motherboard on the core voltage, FSB, frequency multiplier jumper. According to the motherboard specification and CPU frequency, set the above corresponding jumper. Usually, the motherboard on the corresponding CPU voltage is a set of jumpers, each jumper corresponds to a voltage value, find the appropriate voltage value, plug in a key cap short it, select the voltage value. Similarly, find the FSB jumper and frequency multiplier jumper, respectively, to set the appropriate FSB and frequency multiplier. Note that only one jumper can be selected in each set of jumpers.

The new motherboard is more user-considered and uses almost all similar soft jumpers, leaving only the CMOS jumper switch on the motherboard using the most original key-cap jumper, which is mostly a three-pin jumper, as shown in Figure 1. Usually, the short pin 1, 2, indicating the normal use of the motherboard CMOS, and short of 2, 3 means to clear the CMOS content.

Prohibit write BIOS function is not every motherboard, generally two-pin jumper, specifically short to write bios or disconnect to write bios, to see the motherboard instructions.

Some motherboards will let the user choose the soft jumper or dip jumper. such as Asus P4T, if the motherboard on the 10 dip switch is all set to OFF, the use of the soft jumper settings in the BIOS, otherwise, select Dip jumper, where the switch 6~10 said FSB settings, the motherboard specification on a large table, Need to control the table operation, select the appropriate FSB, DIP switch 1~4 to indicate the multiplier, it has 2 of 4 power species State, that is, 16 states, can allow users to choose 16 voltage values.
