You may need to access the BIOS setup for a number of reasons like
- Configure hardware
- Set the system clock
- Enable or disable system components
- Select which devices are eligible to be a potential boot device
- Set various password prompts, such as a password for securing access to the BIOS user interface functions itself and preventing malicious users from booting the system from unauthorized peripheral devices.
Entering BIOS is simple, if you know the key combinations for your computer.
Steps to Enter BIOS setup screen
1. Turn ON your computer or restart if it’s already ON
2. When you find the BIOS screen within few seconds of computer start, search for the message that shows which key to press for entering the BIOS.
3. The message may differ depending upon the mother board. But most common message is
“Press <key> to enter setup”.
Here the <key> refers to a single key or the key combination for entering the BIOS setup depending on your Mother board.
The default key that most computer manufacturers use is Delete Key. But many motherboards use some other keys such as Function Keys (F2 is the most popular key) and even Escape Key.
4. Press the <key> shown in the screen to enter into the BIOS setup screen. Again depending upon the BIOS manufacturers the BIOS setup screen differs.
Note : You may also need to press the <key> several times during first few seconds of the computer startup. Don’t press the key and hold it down as it does not serve the purpose.
5. If your computer shows an image instead of BIOS message, press Escape or Tab Key to show the BIOS Message. By default, most of the motherboard manufacturers configure their motherboard to show their logo instead of BIOS message.
6. If your computer starts too quickly to note the <Key> combination, then press Pause/Break Key to pause your computer startup. After noting down the <key>, press any key to continue to resume your booting.
7. If your computer is too fast, then you may have problems in pressing the Pause button in time. Try turning ON your computer without a Keyboard. Most computer’s will halt startup showing an error that “No Keyboard” is present. You can use this time to note down the key combination.
Note : If you have a USB keyboard, then it will allow input only after POST. In this case, you need a PS2 keyboard to enter into the BIOS Setup screen.
Important: The BIOS configuration has all the system level configurations, a slight misconfiguration in the BIOS can cause problems in your smooth running of your computer.
But you can always restore the BIOS to its factory default settings, if your computer is facing any problems after you change the BIOS settings. Check How to Reset your Bios to Default for help in resetting BIOS to default.
