Oops! Jumper (BIOS Recovery)
The Oops! jumper function is provided in the event the BIOS settings you have selected prevent you from
booting the system. By using the Oops! jumper you can prevent the current BIOS settings in flash from
being loaded, allowing you to boot using default settings.
Use a jumper to connect the DTR pin (4) to the RI pin (9) 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 return to BIOS Setup. You must now load factory defaults by selecting Load Optimal
Defaults from the Exit menu. Then select Save Changes and Exit to reboot the system. Now you can modify
the default settings to your desired values. Ensure you save the changes before rebooting the system.
To convert a standard DB9 connector to an Oops! jumper, short together the DTR (4) and RI (9) pins on the
front of the connector as shown in
on the Serial Port 1 DB9 connector.

Remote Access
The CoreModule 745 BIOS supports Remote Access (or console redirection). This I/O function can be
utilized through 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.
Remote Access Setup
The Remote Access feature is implemented by connecting a standard null modem cable or modified serial
cable (“Hot Cable”) between one of the serial ports (Serial 1 or 2) and the serial terminal or a PC with
communications software. The BIOS Setup Utility controls the Remote Access settings on the
CoreModule 745. Refer to
“Remote Access Configuration” on page 40
for the settings of the Remote
Access feature.
Hot (Serial) Cable
To convert a standard serial cable to a “Hot Cable”, certain pins must be shorted together at the Serial port
header or on the DB9 connector. Short together the RTS (7) and RI (9) pins on either serial port DB9
.
