Oops! Jumper (BIOS Recovery)
The Oops! jumper is provided in the event you’ve selected BIOS settings that prevent you from booting
the system. By using the Oops! jumper you can stop the current BIOS settings in the CMOS from being
loaded, allowing you to proceed, using the default settings. Connect the DTR pin to the RI pin on Serial
port 1 (COM 1) prior to boot up to prevent the present BIOS settings from loading. After booting with
the Oops! jumper in place, remove the Oops! jumper and go into BIOS Setup.
To restore your BIOS setting changes without the errors, you must first select Load Factory Default
Settings, which will automatically load and save the defaults and reboot the system. Then you can
modify the default settings to your desired values. Ensure you save the changes before rebooting the
system.
NOTE The CoreModule 420 Serial Port 1 (J3) is a 10-pin header and uses
pin 7 = DTR and pin 8 = RI. At Serial Port 1, short pin 7 to 8, as
shown in Figure 3-2. Alternatively, you may short the equivalent
pins on the DB9 connector attached to Serial Port 1 as shown in
Figure 3-2.

Serial Console
The CM 420 BIOS supports the serial console (or console redirection) feature. These I/O functions are
provided by an ANSI-compatible serial terminal, or the equivalent terminal emulation software running
on another system. This can be very useful when setting up the BIOS on a production line for systems
that are not connected to a keyboard and display.
