If you’re trying to make changes to your computer’s hardware or software, you may need to access the BIOS setup. BIOS stands for Basic Input/Output System and is essential to any computer’s functionality. In this article, we will discuss how to enter the BIOS or CMO setup in Windows XP Professional.
Due to the wide variety of computer and BIOS manufacturers over the evolution of computers, there are numerous ways to enter the BIOS or CMO setup. For new computers manufactured in the last few years, you can enter the BIOS setup using one of the five keys shown below during the boot process:
These keys are to be pressed randomly as the computer is booting up. Some older computers may also display a flashing block to indicate when to press the F1 or F2 keys. If you are still unable to enter the BIOS using the methods listed above, check the motherboard’s manual for the appropriate key to enter BIOS.
Once you have successfully entered the CMO setup, you should see a screen similar to this. Your CMO setup may look a little different depending on the manufacturer, but should still have most of the same options in the menu on the left or along the bottom of the screen.
To change and save changes in CMO setup, the method for changing the settings often depends on the BIOS manufacturer. You may use the arrow keys along with the enter key to select category and change their values. All manufacturers show which keys navigate on the bottom or right-hand side of the screen.
If you are trying to change the clock speed or other settings and do not have the option available, it is because it is not supported by the motherboard. If you believe it should be supported, you may need a BIOS update. If changes you made appear to revert back to default settings, or if the date and time setting in the BIOS keeps falling behind, you may need to replace the CMOS battery.
If any changes are made, you need to save those changes by pressing the F10 key on the keyboard. If F10 does not work, look at the bottom or top of a screen for the key that is used to save the settings.
For older computers before 1995, there were numerous methods of entering the BIOS setup. Some of the most common included:
– Ctrl + Alt + ESC
– Ctrl + Alt + Intz
– Ctrl + Alt + Enter
– Ctrl + Alt + S
– Page Up key
– Page Down key
If none of the above suggestions allow access to your CMO setup, you can create a Stuckey error causing the CMO setup prompt to appear until you press a key to continue. To do this, press and hold any key on the keyboard and do not let go. You may get several beeps as you are doing this. Keep pressing the key until the computer stops booting and you have the option to enter setup.
Overall, entering the BIOS or CMO setup on Windows XP Professional can be tricky, but it is essential for any computer user. By following the suggestions outlined in this article, you should be able to access the setup and make any necessary changes.
