System Recovery
Reset Button Recovery
The CMX32M provides several methods for recovering from an incorrectly configured system. In order to enter
the recovery mode, follow the steps below:
1.
Remove power from the system, including standby power.
2.
Press and hold the reset button attached to the Utility Connector.
3.
Apply power to the system while continuing to hold the reset button.
4.
Wait the amount of time shown in Table 63 for the desired recovery mode.
5.
Release the reset button, allowing the system to boot.
Load Default BIOS Settings
Loading BIOS defaults allows recovery from an incorrectly configured display device, incorrect boot options, and
many other incorrect settings. It is also a good starting point when making BIOS changes. After restoring defaults,
the BIOS settings should be reviewed and modified as needed.
The default BIOS can be restored either by using Reset Button Recovery, or the “Load Defaults” option in the
BIOS.
Serial Power On Self Test POST Code Output
The POST Codes represents a series of events that take place in a system during the Power On Self Test. If the
POST fails the system will not boot as expected. Knowing which POST code the failure occurred may help system
debug.
This recovery mode configures serial port connector
CN3
as dual RS-232, and sends the POST codes on the
second port (i.e. pin 7 is the transmit pin). The port settings are 115kbps, 8 bits, no parity, one stop bit. When
using this recovery mode, the POST codes can be logged on another computer running terminal software.
Contact RTD technical support for more details.
BIOS Boot Block Recovery
This recovery mode allows you to re-load a BIOS that has been corrupted. The BIOS can be loaded from a file on
a USB key or other removable drive. In order for this to work, the boot block of the BIOS must still be intact.
