5. What is meant by "Restore the nonvolatile memory found in Intel-based system boards?"
This relates to clearing the Real Time Clock (RTC) CMOS memory that contains PC configuration data.
6. Does resetting the CMOS configuration memory return the PC back to factory defaults?
The process of resetting the CMOS will return certain system settings to factory default but will not
reset many of the system data and configuration defaults to their default settings. To return these
system data and configuration defaults to default settings, refer to question and answer 1
and follow the instructions for returning the BIOS settings to factory defaults.
