How to configure the BIOS

The BIOS is the most basic and important system software, which is stored in a special chip, which plays a key role in the process of computer startup and operation. The BIOS setup tool allows you to configure your computer's hardware environment as needed to prepare for system initialization.

The BIOS is the short name of the basic input output system. is the most basic and important program in the computer, which is stored in the Flash ROM of the motherboard.

The role of BIOS

The BIOS is responsible for the underlying work of the computer, including power-on self-test, device initialization, and boot operating system.

(1) power-on self-test

POST (Power on-Self test, power-on-test) refers to the testing of hardware devices when the computer is plugged in, or a warning message or siren if a problem is found.

(2) initialization

Save the parameters of the computer hardware and read the parameters when the computer starts to achieve the purpose of the system initialization.

The hardware parameters are stored in the Flash ROM or CMOS (complementary metal oxide semiconductor, complementary metal oxide semiconductors) chip.

CMOS is a computer motherboard of a read-write RAM chip, can be powered by the battery on the motherboard, even if the computer loses power, the information stored therein will not be lost.

(3) booting the operating system

The BIOS reads the boot record (BR) from the specified storage device in a pre-set order or user selection, and if a boot record is found, the BIOS gives the computer control to the boot record and has a boot record to load the operating system into memory.

CMOS Setup utility (CMOS settings tool)

The CMOS Setup utility (or CMOS setup utility) is part of the bio to set the hardware parameters to initialize the system.

(1) Enter CMOS Setup utility

The BIOS will provide a hotkey to enter the CMOS Setup utility when the computer starts, usually the "delete" key or the "F2" key.

①delete/del

Start the computer when the display "Del:setup", "Press Del to enter Setup", "Presses del to RUN Setup" or "press [Tab]to show post Screen,[del] to Ente R Setup, press the "Del" or "Delete" key of the keyboard to enter the CMOS setup utility.

② Other hotkeys

Start the computer, when the "press XX to enter Setup" or "Presses XX to Run Setup" (XX on behalf of its keys, such as F1, F2), pressing the corresponding keys on the keyboard, you can enter the CMOS setup utility.

Different versions of the BIOS respond to different keys, but will display the message when the computer starts, carefully observe, will find the way into the CMOS setup utility.

BIOS Response button time is relatively short, if the prompt message is not displayed in a timely manner, you must restart the computer to regain key opportunities.

(2) Setting the interface style of the tool

The bios of the manufacturer and version, the Settings tool has a different interface style, mainly has the following two styles of interface, respectively, such as:

Even with different versions of the same vendor, the setup options will be different, as long as the key words of the common settings are remembered, the BIOS settings are not difficult to master.

Award CMOS SETUP UTILITY

The award CMOS Setup utility uses the classic Blue interface style and is familiar with the operation of this style setting tool, so you can master the use of most BIOS setup tools.

(1) Operating instructions

The following is a common key description, the setting tool has a corresponding prompt.

ESC: Exit.

F10: Save and exit;

Arrow keys (top, bottom, left, right): Toggles the selection between menus.

Enter: Enter the submenu.

Pageup/pagedown: Modifies the value of the setting item.

(2) Standard setting

Select the award CMOS SETUP UTILITY menu to identify and modify the computer's time, display the number of hard drives, and interface. In this example, a 6.4GB hard drive is connected to the motherboard's primary master interface.

Example 1.1 shielded floppy drive

Floppy disk due to low capacity, read and write slow, has exited the historical stage, but some bios still put the 3.5-inch 1.44MB floppy disk drive as the default a drive, the computer Qidong will be detected, if the floppy drive is not detected, some BIOS will prompt the error.
