BIOS settings are a menu that almost anyone who has an enthusiasm for formatting on a computer is tampered with. Many people unknowingly make changes to the BIOS menu and have trouble finding solutions. Let's try to recognize the unknowns of the BIOS menu now.
What is the BIOS?
BIOS (Basic Input Output System) enables the system to be powered on by controlling the input and output devices. The BIOS is permanent software and is stored in ROM memory. The software that enables us to use many features of the motherboard establishes a connection between our systems and hardware.
What are the duties of the BIOS?
Tests hardware like RAM , graphics card on boot (BOOT).
Adjusts thevoltagelevels of theequipment.
It isused to determine the starting drive to operate the system in a system other than the hard disk.
Itallows us to turn off unused hardware parts.
How To Open BIOS Setup?
The opening key may differ from computer to computer. Usually , it is opened using "F2 " , " F10", " DEL" keys. With this menu, we can make the changes we want in mainboard. The "+" and "-" keys on the keyboard are used to change the settings in the menu . After making the settings, exit is done by saving the settings in Exit section.
We can count the most used BIOS brands on the market as
What is CMOS?
CMOS (Complementary Metal Oxide Semiconductor) is a memory chip in the BIOS chip that contains initialization information and consumes very low power. When starting the computer, it gets information such as BIOS, date, time etc. from this memory. It derives its power from the battery we call the BIOS battery .
What are the BIOS menus?
►STANDARD CMOS SETUP
►BIOS FEATURES SETUP
►CHIPSET FEATURES SETUP
►POWER MANAGEMENT SETUP
►LOAD BIOS DEFAULTS
►LOAD SETUP/PERFORMANCE DEFAULTS
►SAVE & EXIT SETUP
►EXIT WITHOUT SAVING
Standard CMOS Setup
► Date / Time is the tab where the system time and date are set. ► Hard Disk is the partition where the BIOS will be introduced automatically (AUTO) or manually . ► Disk Drives determines the type of your floppy drive. ► Halt On is the section where it is determined what to do if the BIOS encounters any errors while testing .
BIOS Features Setup
► Virus Warning provides warning for viruses in the Boot sector. ► CPU Internal Cache is a memory that can be kept open to increase system performance. ► External Cache is a feature found on all new motherboards and should be in the "ENABLED" position. ► Quick Power on Self Test (POST) is the section where the speed of the opening test is set. ► Boot Sequence is the tab from which drive the operating system is decided to start. ► Floppy Disk Access Control is the partition where information sharing is set from the hard disk to other devices. ► Boot Up Floppy Seek while the computer is starting upIt asks if the floppy drive should be checked. ► Boot Up Numlock Status, it is set whether the Numlock key will be active at startup. ► Security Options, in this section, the password is set to boot the computer . ► Typematic Rate is set how many characters can be entered from the keyboard in one second. ► Typematic Delay, delay time between two character spelling is determined. ► PS / 2 Mouse Function Control must be "ENABLED" if the mouse is used from the PS / 2 port. ► HDD SMART Capability is the part of the disk test. ► Video ROM BIOS Shadow, the BIOS of the video card RAMMoves to.
Chipset Features Setup
► This is the section where the chipset settings are changed. But changing settings is not recommended. Because while the motherboard is sold, it is sent with the most ideal settings.
► VGA Shared Memory Size is the section where you can set how much RAM the video card will use. ► 8/16 Bit I / O Recovery Time should be left at Default settings. ► Onboard PCI IDE is a tab required for the IDE (Integrated Electronic Devices) device to use the PCI bus . ► Data Integrity Mode, if your memory is a memory with error correction, "Non-ECC" is done if it is not "ECC". ► Current CPU CORE Voltage, the operating voltage of the processor is displayed. ► CPU Fan Speed shows the fan speed of the processor . ► Current System Temperature shows the temperature values of the sensors in the system. ►CPU Temperature allows the processor to warn if it exceeds the specified operating temperature. ► Shout Down Temperature, the computer turns itself off if the processor exceeds the specified temperature. ► On Chip USB must be left in the "ENABLED" position to use the USB devices in the system . ► Fan Fail Alarm warns when the operating speed of the fans in the computer is reduced. Integrated Peripherals ► Power On Function allows us to set how we want to turn on the computer (keyboard, mouse, etc.). ► IDE HDD Block Mode must be in the "ENABLED" position on disks larger than 2 GB. ►On Chip Primary / Secondary IDE provides control of IDE 1 and IDE 2 circuits . ► Onboard FDC Controller provides control of the floppy drive. ► USB Controller controls USB ports . ► USB Keyboard Setup, USB keyboard permissions are set. ► UART Mode Select is a section that can be adjusted according to the use of infrared devices. ► On Board FDD Controller provides FDD control. ► On Board Parallel Port, Working addresses of parallel ports are set. ► PWRO the After PWR Fail, this setting means is electricallyyour computer can automatically turn itself on when it goes back and forth. ► PS / 2 Mouse Power On is set to "ENABLED", the computer is turned on as soon as the mouse button is pressed. ► Keyboard Power On, in "ENABLED" position, the computer turns on when any key is pressed on the keyboard.
Power Management Setup
This sectionprovides adjustment of thecomputer's energy consumption. ►Power Management, this section includes allpoweroptions. ►PM Control by Apm allows power management by computer. ►Automatic Power Up allows the computer toturnonautomaticallyat the set times. ►Video Off Option, this tab is alsoset when themonitorgoes into saving mode. PNP / PCI Configrutaion
►It is the section where the Plug and Play operating systems are set. If you want to use the BIOS, this setting should be saved as "NO".
► If you have PnP Os Installed, Plug-and-Play operating system, do "YES".
► Resources Controlled By, "AUTO" setting is recommended. In this setting, IRQ is automatically assigned to each bus. If you want to make the settings manually , you must select the appropriate slots yourself.
Load BIOS Defaults
►This setting is used if you enter the BIOS settings incorrectly or you want to restore them.
Save & Exit Setup Enables you to exit bysaving the settingsmade.
Exit Without Saving Enables to exit without saving the changes. Load Setup / Performance Defaults Restores the settings in which the BIOS system can operate at optimum performance. Supervisor Password The password is thespecified part for controlling BIOS settings by a single person. User Password It only puts the password on the system, it does not affect the BIOS. ►If there aredifferentmenus on yourcomputer that you do not know, please specify as a comment. Let's try to help.
