【 Weak current College 】 describes IDE interface hard drive jumper jumper settings method---Power By 【 China power house network 】

To recommend a good use of hard drive jumper, like everyone on the hard drive jumper, and then on the hard drive jumper comprehensive explanation describes, in the hope that is useful to everybody. Jumper while type variety, but it is mainly present in the motherboard, hard drive jumper, optical drives these three hardware, video cards, sound cards and other accessories in the relatively rare. Here we follow learning jumper.

Motherboards jumper

Jumper up to the most complex is the motherboard jumper. In General, the motherboard jumper mainly include CPU setting jumpers, BIOS clear jumper, jumper BIOS prohibition. These jumpers, set the jumper CPU is the most complicated, it mainly has the CPU multiplier and FSB, voltage, three jumper.

On board the corresponding CPU multiplier jumper is a set of jumpers, each jumper corresponds with a multiplier that you want to find the appropriate multiplier value (or jumper combo), and then unplug the keycap shorted it (or pull to ON), this multiplier is set.

By the same token, when setting the CPU FSB jumper and voltage jumper is too, but it is important to note that the CPU FSB, double frequency and voltage setting is the most complex and each motherboard settings may not be the same, it is recommended that you set before you must carefully read the motherboard manual, follow the instructions in the specific instructions for hands-on, safer.

Motherboard manufacturers in order to reduce the user's workload, but also to attract user attention, has above the CPU FSB, multiplier and voltage jumpers are moved to the motherboard BIOS Setup, so now the motherboard has been harder to see than jumper, sometimes see also three of one or two.

In the motherboard jumper has existed in the BIOS to clear jumper. When we forget the BIOS password, the most direct way is to open the case, find the BIOS clear jumper (it usually next to the motherboard battery) to clear. Typically, clear information, as long as BOIS will be key cap from 1, 2-pin unplug and then plug in 2, 3-pin (expressed clear BIOS content) is cleared, then Reseat keycap 1, 2-pin.

Just now we introduce the main on the Board, in fact, the jumper on the motherboard with some small jumper. Like the keyboard on the jumper, etc., of the specific situation depends on you own to see your motherboard documentation. For the convenience of everyone, some manufacturers also on board set the jumpers on hard and soft jumper between the jumper function. Like Asus P4T motherboard, if we put 10 DIP switch all set to "OFF", then we can use the BIOS soft jumper, otherwise, only hard-jumper.

Hard drive jumper

Hard drive jumper on the system with master and slave. These two States are usually in a set of jumpers in the control. Most of the hard drive jumper jumper settings on the hard drive jumper power socket and cable outlet, and of course there is also a small part is set in the circuit board (such as: Samsung WN312021A hard drive jumper). Due to the hard drive jumper by interface is mainly divided into IDE and SCSI interface, so the hard drive jumper's jumper has two situations, where we introduce the IDE interface hard drive jumper jumper settings.

Current personal computer hard drive jumper mostly IDE interface, because the manufacturers are different, their settings there are significant differences. However, they are divided into three jumper settings, that is, Master, Slave and CableSelect three. Which Master indicates primary disk (normally the factory preset values), the Slave is a slave, but CableSelect refers to data line answered the IDE device, from the "identity" is received by them in the location on the data line.

ATA only use CableSelect/66 and ATA/100 dedicated cable can be achieved, and ATA/66 and ATA/100 dedicated cable blue connector must be connected to the motherboard IDE connector, connect the cable between the plug devices must be connected from disk, the data line end plugs on the device or the primary disk.

As vendors, standards are not standard and determine hard drive jumper's jumper is varied. However generally hard drive jumper spare body reverse text we can find the detailed setup instructions. Hard drive jumper jumper is actually a set of key Cap-jumper, we just follow the instructions in the keycap corresponding PIN.

In General, if our IDE interface (channel) on only by one hard drive jumper (no other IDE devices), we do not require a jumper. Only when IDE connector on the two devices only need to be set, otherwise it will cause a conflict. In general the IDE1 connector on the hard drive jumper settings for master and the other IDE device (such as another hard drive jumper or optical drive) is set to slave, this can improve overall system performance.

Optical jumper

Optical drive (including burner, DVD-ROM) and hard drive jumper, mostly IDE interface, they are also called IDE device. Jumper settings and hard drive jumper almost, in General, the jumper in the optical drive data cable from the left, it consists of three sets of pins. Represent the three States, namely, the Master, Slave and CableSelect. The motherboard is different is the optical drive of jumper description is generally printed on the CD-ROM jumpers over metal case above, we just follow the above instructions to set it.

In General, people will drive IDE2 connector installed on the motherboard, and set the master (actually drive the factory default values is the master, so do not set up to use). But if the IDE2 connector on the existence of the second IDE settings (such as a second hard drive jumper, the recorder or DVD, etc.)We are the main settings, from disk, or system does not recognize. At the same time we should note that due to the hard drive jumper jumper with CD key cap are embedded in the jumper inside plug by hand, generally difficult, it is recommended that you use tweezers.
