Most of the CMOS jumper CMOS jumper is near the motherboard battery. Its setting is relatively simple, only two ways: Normal and CLEAR CMOS (generally have a description of the jumper near the CMOS jumper). When set to 1-2 (short), it is normal; when set to 2-3 (short), to clear the CMOS setting, it can be used to clear the CMOS password, the boot password, etc. (as shown in Figure 6). Figure 6 CMOS jumper hard disk jumper, the default settings when the hard disk is shipped, is the primary disk, when only one hard drive is installed; but when installing multiple hard drives, it is necessary to re-re-hard disk jumper. already setup. The jumper on the hard disk is relatively simple, and its jumper position is more on the hard disk, and the power cord interface (as shown in Figure 7). Figure 7 Hard disk jumpers also have instructions on jumper settings on the surface of the hard disk, taking the Seagate hard disk as an example (as shown in Figure 8), there are four sets of settings: "Master or Single Drive" (indicating that the hard disk is the primary disk or that Only one hard disk is connected to the channel, that is, the hard disk exclusively an IDE channel. This channel cannot be slave on this channel), "Drive is slave" (indicating the current hard disk as slave), "Master With A Non-ATA Compatible Slave" Indicates that there is a primary disc, and the slave is a hard disk that is not compatible with the ATA interface hard disk, which includes the old-fashioned hard disk or SCSI interface hard disk that does not support DMA33. "Cable Select" (using the data cable to select the hard disk master, this way After special processing data cable to set the primary disk and slave disk, the 28th data line is a selection line, it is the primary disk, which is not worthwhile to slave. True support for this function, the market is rarely ). Figure 8 Jumper of the hard disk surface Description Tip: The hard disk jumper has no uniform standard, different brands of hard drives, and jumper setting methods may vary. Usually we can find the jumper instructions on the front or IDE interface of the hard disk, or the IDE interface. The optical drive jumper optical drive is set by default to slave. The optical drive jumper is very similar to the hard disk jumper, and its jumper position is more behind the optical drive, the data cable interface and the power cord interface. Generally only Master (primer), slave, Cable Select (cable selection), very few other cases, all brands of optical drives are almost like this, relatively standard, make settings simple. Usually we can find the jumper instructions on the upper part of the IDE interface (Figure 9). Figure 9 CD-ROM jumper Description Tip: If the optical drive and the hard disk share an IDE data cable, the optical drive jumper is usually selected as slave, and the hard disk is set to Master.
If the optical drive is a stand-alone IDE line, you can jump into the master. : Why is the computer will automatically restart after shutting down?
This problem is more common, and the wake-up function in the power management in the BIOS can be resolved.
If you are award BIOS, you can set "Power By Ring", "Wake-up BY PCI Card", "Wake By LAN", etc. in Power Management Setup, "Wake By LAN", and "Wake By LAN".
