device driver. Try removing the new hardware and see if the system will
start. If it does, consult with the device manufacturer for information on
solving the problem. In some cases, a firmware or driver upgrade may
resolve the problem.
6.6.3 Plug and Play Problems
This motherboard supports the automatic recognition and configuration
of expansion cards that support the Plug and Play (PnP) specification.
Most currently available expansion cards support PnP. PnP simplifies
card installation by allowing the system to handle system resource alloca-
tion. If you install an expansion card that is not PnP compliant, you may
still need to configure the card manually. Consult the card’s documenta-
tion for instructions or other information.
6.6.4 Replacing the System Configuration Record
As noted previously, the CMOS Setup Utility creates a system configura-
tion record and stores it in CMOS memory on the motherboard. This
record must be correct and uncorrupted for the system to operate prop-
erly. It is possible for the system configuration record can become cor-
rupted or lost. If this occurs, the system will not operate properly or at all.
This is not a serious problem.
You can restore a working configuration using the CMOS Setup Utility to
create a new configuration record by loading the Optimized Defaults and
reentering any other settings you had made.
6.6.5 Loading Optimized Defaults
The CMOS Setup Utility does not require an operating system to run.
You run the utility by typing the Del or Delete key while the system is
starting up to brings up the utility’s main screen.
There are two sets of defaults listed, Optimized and Fail-Safe. The Fail-
Safe Defaults are a minimum configuration set for use by technicians
when troubleshooting system problems. The Optimized Defaults are what
the system normally operates on. If a corrupted system configuration
record caused the problem you experienced, once you load the Optimized
Defaults and reboot, the system should function normally. The instruc-
tions on the next page illustrate this procedure.
You can easily restore a working system configuration record from the
main screen of the CMOS Setup Utility.
To do so, do as follows:
1. Select the “Load Optimized Defaults” item.
