How to backup the CMOS values.

Solutions:

Print CMOS values

It is possible that the CMOS setup program may allow you to print the values of your CMOS setup. If available, it is recommended you backup the CMOS values by printing a hard copy of the current CMOS values. These values can then be re-entered if needed. 

Third-party utility

There are various utilities available on the Internet and sometimes from computer manufacturers that will allow you to make backups of your computer CMOS. These utilities are not always compatible with all versions of CMOS or types of CMOS, so be cautious.

We have available on our hardware download section a file that we have found helpful called cmos.zip, which allows you to do various helpful things with the computer CMOS.

Additional information:

There are a few methods that can be done to backup the CMOS values. It is also important to know that most computers today will automatically backup the default CMOS values on the BIOS chip.
