SYSTEM BIOS Objectives: Describe how the BIOS/ works Change the BIOS setting accordance with hardware requirements Follow the proper procedure in changing the BIOS. What is BIOS? Basic Input / Output System is an essential component of the motherboard. This boot firmware, also known as System BIOS or, on most recent systems, unified extensible firmware interface (UEFI), is the first code run by a computer when it is booted. It prepares the machine by testing it during bootup and paves the way for the operating system to start.  It tests and initializes components such as the processor, RAM, video card, hard drives, optical, and USB drives. If any errors occur, the BIOS/UEFI reports them as part of the testing stage, known as the power- on self-test (POST). The BIOS/UEFI resides on a ROM chip and stores a setup program that you can access when the computer first boots up. How to configure Basic Input Output System (BIOS): 1. Turn on or restart your computer. 2. Press "Esc," "Del," "F1," "F2," "Ctrl-Esc" or "Ctrl-Alt-Esc" as soon as BIOS type or version appears on screen to enter BIOS Setting. There is usually a line of text at the bottom of the display that tells you "Press ___ to Enter Setup.” 3. Adjust all available features within the basic or standard BIOS section. 4. Once you have entered setup, you will see a set of text screens with several options. Some of these are standard, while others vary according to the BIOS manufacturer. Common options in BIOS according to manufacturer System Time/Date Set the system time and date Boot Sequence The order that BIOS will try to load the operating system. This controls the order in which the PC looks at the drives for bootable information. Mouse/Keyboard "Enable Num Lock," "Enable the Keyboard," "Auto- Detect Mouse" Drive Configuration Configure hard drives, CD-ROM and floppy drives Power Management Select whether to use power manageme nt, as well as set the amount of time for standby and suspend Integrated Peripherals This menu allows you to change the various I/O devices such as IDE controllers, serial ports, parallel port, keyboard etc. You can make changes, as necessary. PnP/PCI Configurations This menu allows you to configure your PCI slots. You can assign IRQ's for various PCI slots. It is recommended that you leave the default settings as it can get a bit complicated messing around with IRQ’s  PC Health Status This menu displays the current CPU temperature, the fan speeds, voltages etc. You can set the warning temperature which will trigger an alarm if the CPU exceeds the specified temperature.  Set Password Password protect your BIOS you can specify a password. Make sure you don't forget the password, or you cannot access the BIOS. The only way you can access the BIOS is by resetting it using the reset jumper on the motherboard. Exit Setup Save your changes, discard your changes or restore default settings BIOS Keys by Manufacturer ASRock: F2 or DEL Lenovo (ThinkPads): Enter ASUS: F2 for all PCs, F2 or DEL then F1. for Motherboards MSI: DEL for motherboards and Acer: F2 or DEL PCs Dell: F2 or F12 Microsoft Surface Tablets: Press and hold volume ECS: DEL up button. Gigabyte / Aorus: F2 or DEL Origin PC: F2 HP: F10 Samsung: F2 Lenovo (Consumer Toshiba: F2 Laptops): F2 or Fn + F2 Zotac: DEL Lenovo (Desktops): F1 FAQ (Frequently Asked Questions) Is BIOS hardware or software? BIOS is alternately called ROM BIOS, PC BIOS, and System BIOS. BIOS is the first software that runs when you power on your system, performing an initial pack of diagnostic tests (POST, or Power On Self-Test) to see if there are any issues with the hardware. Is BIOS a memory? A computer's basic input/output system (BIOS) is a program that's stored in nonvolatile memory such as read-only memory (ROM) or flash memory, making it firmware. The BIOS (sometimes called ROM BIOS) is always the first program that executes when a computer is powered up. What is a Firmware? Firmware is a type of software that is embedded directly in a piece of hardware to make the hardware work as intended. Firmware is programmed by the manufacturer and is installed on a digital device right in the factory. All computing devices have firmware. Why does a computer need a BIOS? Helps the computer to locate software and complete the boot process. The BIOS software often lives on the Read-Only Memory (ROM) or flash memory chip connected to your computer's motherboard. What data is stored in BIOS? 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. What happens if the BIOS battery dies? In case of a battery failure, it can no longer set the correct date and time, which is why it keeps resetting every time you shut down the device. The time and date will reset even if you put the correct date as well as time in BIOS settings. It will reset the time as well as the date by default. QUESTION:
