5.9. DEFAULT VALUES
The configuration parameters are saved in a particular area of memory (CMOS
RAM) which is call NON VOLATILE because it has a battery back-up that allows the
saved values to be maintained even in the event of a power failure or if the main
batteries are not available (not present/run down).
It may happen, though, that the saved values are unreliable either because the
battery back-up is run down or the data have been changed for some reason.
Only during the F7400 terminal’s boot sequence does the BIOS perform the
function tests of the CMOS RAM and of the data reliability before using them for
the F7400 terminal’s configuration: if the BIOS encounters problems of functioning
or data non-integrity, it proceeds by loading the EEPROM values into the CMOS
RAM, if the EEPROM values have never been written, it loads the default values to
allow the terminal to be used safely.
If the BIOS cannot use CMOS and/or EEPROM values, it sends a message indicating
the kind of encountered problem, you can see this message after the end of the
RAM test.
If the BIOS uses the default values, all the configuration parameters are reset to
their default values – this applies also to the PASSWORD (because it was corrupted).
You can choose to use our default configuration invoking the BSETUP.EXE
application with the “-d” option or by selecting the factory default item on the exit
page, (your password will remain valid).
