BIOS Setup Utility
This chapter provides information on BIOS Setup Utility and instructions on how to use it to
configure the system.
NOTE:
For ease of reading, BIOS Setup Utility will be simply referred to as “Setup Utility” or “Setup” in
this guide.
Setup Utility Overview
BIOS Setup Utility is a hardware configuration program built into your system's Basic
Input/Output System (BIOS). Since most systems are already properly configured and
optimized, there is normally no need to run this utility. You will need to run this utility under
the following conditions:
•
•
When changing the system configuration including:
— Defining the diskette drive
— Defining the serial or parallel (COM/LPT) ports to prevent any conflicts
— Setting the system time and date
— Configuring the hard drives
— Specifying the boot device sequence
— Configuring the power management modes
— Setting up system passwords or making other changes to the security setup
When a configuration error is detected by the system and you are prompted ("Run Setup"
message) to make changes to the BIOS settings.
NOTE:
If you repeatedly receive “Run Setup” messages, the battery may be defective. In this case, the
system cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
The Setup Utility loads the configuration values in a battery-backed nonvolatile memory
called CMOS RAM. This memory area is not part of the system RAM, which allows
configuration data to be retained when power is turned off. The values take effect when the
system is booted. POST uses these values to configure the hardware. If the values and the
actual hardware do not agree, POST generates an error message. You must run this utility to
change the BIOS settings from the default or current configuration.
