BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your system’s BIOS (Basic Input/Output
System). Since most systems are already properly configured and optimized, there is no need to run this utility.

configuration problems. Refer to Chapter 4 Troubleshooting when problem arises.
