When you operate or repair your computer on weekdays, you can often hear some statements about BIOS settings and CMOS settings, and many people don't know much about BIOS and CMOS, or even confuse the two. Today you master the differences and connections between BIOS settings and CMOS settings. BIOS is an EPROM or EEPROM chip on the motherboard, which contains i

The difference between BIOS and CMOS:1. The so-called bios, in fact, is the basic computer input and output system (basic input-output systems), its content is integrated in a microcomputer motherboard on a ROM chip, the main preservation of the computer system is the most important basic input and output programs, System Information settings, Power-On self-test program and system startup bootstrap program.

Open the chassis, find the battery on the motherboard, and disconnect it from the motherboard (that is, remove the battery). At this time, CMOS will lose all internal storage information due to power failure. Connect the battery and close the chassis to boot. Because CMOS is

CMOS parameters are lost, after the boot prompts CMOS Battery state Low, the computer can sometimes start, using a period of time will panic. The above phenomenon is generally caused by comso power supply. If it is a welded battery, use soldering iron to reconnect with a new

The BIOS is an EPROM or EEPROM chip on the motherboard, which contains important information about the system and setup procedures for setting system parameters (BIOS setup program);CMOS is a read-write RAM chip on the motherboard, which is equipped with the specific parameters of the system configuration, the contents of which can be read and written by the Setup program.The CMOS RAM chip is powered by the

After the CMOS is set, the changed settings cannot be saved. This situation is generally due to the motherboard battery problem, you can replace the motherboard battery. However, the motherboard battery replacement can not solve the problem, there are the following two possible. 1. Motherboard circuit problems

burn the entire equipment, so in the adjustment jumper must carefully read the instructions, check jumper name, jumper column number and break relationship. The most common jumpers on the motherboard have two main types, one being only two needles. This two-pin jumper is the simplest, with only two states, on or off (Figure 3). Figure 32 Jumper method for pin jumper The other is a three-pin jumper, which can have three states: short between 1 and 2, short between 2 and 3 (Figure

take precedence over the setting in the CMOS. 1. Energy-saving settings in the BIOS In CMOS settings, there is mostly a "power savings", where you can select multiple options such as "Maximum Battery Life" and "Maximum performance". "Maximum Battery Life" is the default energy-saving mode setting. There are several

Open the chassis, locate the battery on the motherboard, disconnect it from the motherboard (that is, remove the battery), and the CMOS will lose all information stored internally because of power loss. Then put the battery on, close the chassis on, because the CMOS is a bla

Open the chassis, locate the battery on the motherboard, disconnect it from the motherboard (just remove the battery), and CMOS will lose all internal storage information due to power loss. Re-connect the battery, close the chassis boot, because the CMOS is a blank, it will

In the use of the computer, prompted the CMOS parameters are lost, sometimes the system can be successfully started, but in the use of a panic occurs. The above situation, most of which is due to the lack of CMOS power supply. Different types of batteries need to be replaced in different ways. The CMOS battery is divi
