3.1 Overview
The BIOS is a program that takes care of the basic level of communication between the CPU and
peripherals. It contains codes for various advanced features found in this system board. The BIOS allows
you to configure the system and save the configuration in a battery-backed CMOS so that the data retains
even when the power is off. In general, the information stored in the CMOS RAM of the EEPROM will
stay unchanged unless a configuration change has been made such as a hard drive replaced or a device
added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need to install
a new CMOS battery and reconfigure the BIOS settings.
3.2 Default Configuration
Most of the configuration settings are either predefined according to the Load Optimal Defaults settings
which are stored in the BIOS or are automatically detected and configured without requiring any actions.
There are a few settings that you may need to change depending on your system configuration.
3.3 Entering the BIOS Setup Utility
The SBC EPI-I901’s BIOS Setup Utility can only be operated from the keyboard and all commands are
keyboard commands. The commands are available at the right side of each setup screen. The BIOS Setup
Utility does not require an operating system to run. After you power up the system, the BIOS message
appears on the screen and the memory count begins. After the memory test, the message “Press DEL to
run setup” will appear on the screen. If the message disappears before you respond, restart the system or
press the “Reset” button. You may also restart the system by pressing the <Ctrl> <Alt> and <Del> keys
simultaneously.
