5.1 BIOS SETUP OVERVIEW

The BIOS is a program used to initialize and set up the I/O system of the computer, which includes the ISA bus

and connected devices such as the video display, diskette drive, and the keyboard. The BIOS provides a

menu-based interface to the console subsystem. The console subsystem contains special software, called

firmware that interacts directly with the hardware components and facilitates interaction between the system

hardware and the operating system.

The BIOS default values ensure that the system will function at its normal capability. In the worst situation the user

may have corrupted the original settings set by the manufacturer.

After the computer is turned on, the BIOS will perform diagnostics on the system and display the size of the

memory that is being tested. Press the [Del] key to enter the BIOS Setup program, and then the main menu will

show on the screen.

The BIOS Setup main menu includes some options. Use the [Up/Down] arrow key to highlight the option that you

wish to modify, and then press the [Enter] key to select the option and configure the functions.

Setup Main Menu

The <Main> option allows you to record some basic system hardware configuration and set the system clock and

error handling. If the CPU board is already installed in a working system, you will not need to select this option

anymore.
