Power-On Self Test Warning Messages
The cRIO-9081 POST displays warning messages for specific issues onscreen. You can use
MAX to enable Console Out to send these warning messages through the RS-232 serial port.
Note
When a warning message is displayed, 10 additional seconds are added to the
POST to give the user time to read the warning.
The POST can display the following warning messages:
•
First Boot Detected—This warning is displayed at the first boot of the system after
updating the BIOS firmware. This warning indicates that the BIOS settings have the
default values.
•
BIOS Reset Detected—This warning is displayed when the CMOS Reset button has been
pushed. This warning indicates that the BIOS settings have the default values.
•
CMOS Battery Is Dead—This warning is displayed when the CMOS battery is dead and
must be replaced. The BIOS settings are preserved even when the CMOS battery is dead,
but that the system will boot very slowly because the BIOS cannot optimize boot time by
saving specific system information to CMOS.
