The master and slave devices can be adjusted by the rear jumpers of the hard disk or optical drive. Everyone knows that two different devices can be connected to each data line. Generally speaking, the first group of IDE devices is close to the chip, and the main device, Slave device refers to two devices connected on an IDE data line. The first and second groups of devices refer to the first and second IDE data lines on the motherboard. The IDE devices here include IDE hard disks and IDE optical drives. There are the PRIMARY MASTER first group of IDE master devices PRIMARY SLAVE first group of IDE slave devices the SECONDARY MASTER second group of IDE master devices SECONDARY SLAVE second group of IDE slave devices. The standard CMOS settings include DATE and TIME settings, where you can set the time and date on your computer. STANDARD CMOS SETUP (standard CMOS setting) Next, we will focus on the basic setting method of the AWARD BIOS program. The BIOS program is divided into different manufacturers according to the manufacturer: AWARD BIOS program, AMI BIOS program, PHOENIX BIOS program, and other jumper-free BIOS programs and brand-specific BIOS programs, such as IBM and so on. Using the BIOS setup program can also troubleshoot or diagnose system problems. Its main function is to provide the computer with the lowest and most direct hardware settings and control. The BIOS setup program is stored in the BIOS chip and can be configured only when the machine is turned on. CMOS is mainly used to store the parameters and data set by the BIOS setup program, and the BIOS setup program mainly manages and sets the basic input and output system. The BIOS (basic input output system) setting program is a set of programs that are solidified into the ROM chip on the computer motherboard. However, due to the different motherboards used, the specific BIOS setting items are also different (for more detailed introduction, see “Computer Common Sense: Two Mainstream Bios- AWARD and AMI-detailed explanation of the specific settings of the new version and the old version (picture and text)). Enter BIOS settings and basic optionsĪfter turning on the computer or restarting the computer, when the screen displays “Waiting……”, press the “Del” key to enter the CMOS setting interface (Figure 1). It should be noted that if you press too late, the computer will start the system, and only restart the computer at this time. You can press and hold the Delete key immediately after booting until you enter the CMOS. After entering, you can use the arrow keys to move the cursor to select the option on the CMOS setting interface, then press Enter to enter the sub-menu, use the ESC key to return to the parent menu, use the PAGE UP and PAGE DOWN keys to select specific options, and the F10 key to retain and exit BIOS settings.įor computer enthusiasts, BIOS settings are the most basic and commonly used operating skills. BIOS is the lowest level of the computer system, which has a great impact on computer performance. We can use the BIOS setup program to troubleshoot and diagnose system problems. The BIOS program manages and sets the basic input and output system.
What is COMS? coms It is mainly used to store the setting parameters and data of the BIOS setup program. Today we will briefly talk about the coms setting diagram. For those who often repair computers, COMS may be in touch frequently.
For friends who often play with computers, they may be a little unfamiliar with BIOS and COMS.
