Saving BIOS Settings The diagnostic and utilities disk that comes with the open controller CPU
module includes a

utility that saves current BIOS settings to
a file. You can also use this utility to restore BIOS settings from
information previously saved in a file (using this utility).
Storing BIOS Settings
To save current BIOS settings to a file:
getcmos> filename
The
getcmos.exe
utility works properly under DOS, a DOS shell in
Windows, and a DOS shell in Windows 95. The utility doesn’t work under
a DOS shell in Windows NT.

The revision of BIOS must be the same between the open controller CPU
module and the BIOS data saved to a file. To restore BIOS settings from an
existing file:
getcmos filename
After you restore BIOS settings, reboot to make those settings active.The
real-time clock will not be correct after you restore BIOS settings.
