CMOS setup is a hard ware configuration program built into the system ROM, called the
complementary metal- oxide semiconductor (CMOS) Setup Utility. Since most systems are
already properly configured and optimized, there is no need to run this utility. You will need to
run this utility under the following condition.
When changing the system configuration settings
When redefining the communication ports to prevent any conflicts
When modifying the power management configuration
When changing the password 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 CMOS setup
NOTE:
NOTE:
If you repeatedly receive Run Setup messages, the battery may be bad. In this case,
the system cannot retain configuration values in CMOS. Ask a qualified technician for
assistance.
CMOS setup 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.
Before you run the CMOS Setup Utility, make sure that you have saved all open files.
The system reboots immediately after you close the Setup.
NOTE:
NOTE:
CMOS Setup Utility will be simply referred to as “BIOS”, "Setup", or "Setup utility" in this
guide.
