Learn the BIOS Bios system settings

Bios stands for Base Input Output System and includes options for setting and configuring system settings and settings.
The BIOS or Cmos settings are stored on the motherboard in the IC called IC.
When the computer is off, the battery embedded on the motherboard stores the stored settings. In addition to the settings, the clock and date are also IP data that is protected by this battery. In order to
enter the BIOS configuration section, we must press the Delete buttons, or on some systems, Ctrl + F1 or F12, when we turn on the computer. (Depends on the type of motherboard).
In this section, which is configurable only with the keyboard, you can make a lot of settings that are the most important ones.

Note that the menus and options may vary on different motherboards, but the general principles and concepts of all of them are one that we consider being the main options for the two famous BIOS builders (AMI and Award):
1) Standard CMOS Features
1) The standard features of
this section includes the basic and common settings among all systems, including:

Date & Time:
setting and displaying the date – setting and displaying the clock.

• IDE 0 Master:
Setting and displaying a device that attaches to the motherboard’s IDE0 port The board is installed and is in Master mode

▪ IDE 0 Slave:
Set and display the device that is installed on the motherboard of the IDE0 port and in the Slave mode

▪ IDE 1 Mas ter:
Set up and display the device that is installed on the motherboard of the IDE1 port and in Master mode

▪ IDE 1 Slave:
Set up and display the device that is installed on the motherboard of the IDE1 port and in the Slave mode.

▪ Serial ATA 0:
Set up and display the device that is installed on the motherboard of the SATA0 port.

▪ Serial ATA 1:
Set up and display the device that is installed on the motherboard of the SATA1 port.

▪ Floppy Device [Drive A / Drive B]:
Setting and Enable / Disable the floppy disk drive.

▪ System Information:
Displays general information about the system (on some systems).

Note: Devices such as cd-rom, burner, and hard drive Most of the ATAs are connected to the motherboard with an 80-bit cable called the IDE, as shown below. Most motherboards have one or two IDE ports (ie 2 or 4 ATA devices can be connected to the ATA, sometimes called PATA).

IDE | MyComputer.in

Since the IDE cable has a socket, its two sockets can be installed on two devices, one Slave and one Master. To determine which Master and which Salve, the jumper bars are embedded behind these devices, which can be customized according to the description on the device.

Hard drives and laptops are also available with a larger SATA socket and smaller cables. These devices are connected to the motherboard with a socket called SATA. A SATA device is installed on each SATA port. Currently, most motherboards have 2, 4 or 6 SATA ports.

2) Advanced CMOS Features
2) Special features include special settings
specific to the BIOS system.

For example, most BIOSs include:
(Description: Selectable options are set for each setting inside the bracket)

• Boot Sector Protection: [Enable / Disable]
Enable or Disable the system Protecting unauthorized manipulation of BIOS by viruses or unwanted events

▪ Full Screen Logo Screen: [Enable / Disable]
Display or hide the logo of the motherboard manufacturer at the beginning of the system activation.

• Quick Booting: [Enable / Disable]
By setting this option to Enable, the system starts up checking the settings after 10 seconds. (

Boot Up Num-Lock LED: [ON / OFF]
Specifies the default status of the Numbers Keys)

▪ Boot Sequence [C, if the boot sequence exceeds 10 seconds, ignores checking the rest) CD-Rom, A / A, CD-Rom, C / CD-Rom.C, A / CD-Rom, A, C]
By entering this section, you can give the system’s priority to get up to the desired device.

▪ Hard Disk Boot Priority: [HDD 0 / HDD 1 / HDD 2 / …]
Setting the priority between hard disks to rise (whether the operating system will rise with the help of a hard drive)

▪ First (1st) Boot Device: [Hard Disk / CD-ROM / Floppy / USB HDD / …]
Setting the first device used by the system to boot

▪ Second (2nd) Boot Device: [Hard Disk / CD- ROM / Floppy / USB HDD / …]
Setting the second device to be used by the system to boot. (The second device only refers when the first device was unable to boot the system.)

Third (3rd) Boot Device: [ Hard Disk / CD-ROM / Floppy / USB HDD / …]
Setting the third device used by the system to boot. (The third device only refers when the second device fails to boot the system.)

▪ Other Boot Device
Set up other devices by system Used to boot.
Note: When installing from a Windows CD, we need to place the First Boot Device on a CD-ROM so that the system will go back to the CD drive as soon as it’s turned on.
To install the DOS operating system, we need to install the First Boot Device to the Floppy Disk, so that the system returns to the floppy drive as soon as it is turned on and floppy.

3) Integrated Peripherals
3) Integrated Devices on the Motherboard
Settings for all devices and components on the motherboard (integrated on the motherboard), or Onboard
Onboard devices such as the motherboard sound card system or USB (USB) ports. And (also, in some motherboards, the graphics card embedded on the motherboard) as well as the settings for the network card embedded on the motherboard.
To explain important part of the deal:

▪ USB Controller: [Disable / 2 Ports / 4 Ports / 6 Ports / 8 Ports / …]
Enable or disable the USB ports of the motherboard

This option is enabled if your modem is connected to the telephone line and someone calls you.

5) Pnp / PCI Configuration
5) Configuration and settings for

PCI devices. : Peripheral Compounent Interconnect
and PNP: Plug & Play
PCI devices are devices that connect to the motherboard through the slot (PCI slot). Such as a modem, a tv captcha or an audio card
In this section, each slot of the motherboard can be configured to use which interrupt number (IRQ).
It’s better to choose the Auto option so the system automatically assigns the interrupt number to the devices.

6) PC Health Status or H / W Monitor
6) System Health Status
This section shows the overall status of the system, including fan speed, the current temperature of the system and processor, processor voltage, and so on.
Some of the systems in this section also include the following options:

▪ Chassis Instruction: [Enable / Disable]
Chassis Operations such as Door Opener

▪ Smart Fan Target CPU: [Disable / Level 1 / … / Level 5]

CPU Fan Fail Warning: [Enable / Disable]
Alarm when the faulty processor

▪ CPU Temp Warning: [Disable / 50/60/70/80]
warned the CPU temperature to a certain temperature

▪ CPU Temp Warning: [Enable / Disable]
warning when the failure or malfunction of the system fan (s)

7) Frequency / Voltage Control
7) Voltage and Frequency Control
In this section, you can set the processor frequency and the operating voltage of the RAM and processor, as well as the graphics card voltage connected to the AGP slot.
This part is most used for OverClocking.
The manipulation of this part without proper information may cause the motherboard, processor or graphics card to burn.

8) Top Performance / Loaf Fail-Safe / Optimized Default
8) Basic settings and efficient settings
This section is available with the three above names, including the factory default settings and factory settings as well as the manufacturer’s pre-configured settings.
Some of the common options are:

▪ Load Fail-Safe Default:
Load default settings that override some of the features of the motherboard.

▪ Top Performance & Optimized Default:
Renders the predefined settings that have the most performance on the system motherboard.

9) BIOS Setting Password – Set Supervisor & User Password
9) Password BIOS Settings / User Password Setup
In this section, you can log in or log in to the BIOS settings.
By setting the System Password or User Password, you can set up a passphrase to get the system up, so that someone can not use the computer without a license.
By setting Supervisor Password, you can enter the BIOS settings section of the password.
Note: Removing the battery on the motherboard will clear these two passwords and return all the settings to the factory default setting.

10) Save And Exit
10) Save and Exit the BIOS
In most cases, pressing the F10 key changes the BIOS stored and the system will be restarted and ready to work.
In some motherboards, you have to choose the Save And Exit option to save and exit.
Exit Without Saving also exits the settings section without saving the change
