How to Disable BIOS Settings
BIOS is an acronym for Basic Input/Output System. It is the boot firmware program on a PC, and controls the computer from the time you start it up until the operating system takes over. When you turn on a PC, the BIOS first conducts a basic hardware check, called a Power-On Self Test (POST), to determine whether all of the attachments are present and working. Then it loads the operating system into your computer's random access memory or RAM.
The BIOS also manages data flow between the computer's operating system and attached devices such as the hard disk, video card, keyboard, mouse, and printer. The BIOS stores the date, the time, and your system configuration information in a battery-powered, non-volatile memory chip, called a CMOS (Complementary Metal Oxide Semiconductor) after its manufacturing process. By entering the BIOS menu, computer users can enable and disable BIOS settings at will. By going through each option individually, users can even disable all BIOS functions.
1. Shut down your computer. Turn your computer back on.
2. Press your manufacturer-specified key on the first screen to appear to open the BIOS menu. Each brand of computer requires a different keystroke to open the BIOS menu. Often this is one of the "F" number keys at the top of the keyboard or the "Esc" key.
3. Disable each BIOS setting individually by highlighting it with the arrow keys and pressing "Enter." Each BIOS menu regulates a variety of functions, including memory and power supply options. Navigate through each menu to disable each BIOS setting.
4. Press "F10" when finished to save the settings and exit your computer's BIOS.
