ReadyBoard 910
Temperature Monitoring
The Super I/O controller performs the temperature monitoring function. The board temperatures can be
monitored from the Hardware Monitor feature in the Advanced BIOS setup screen.
User GPIO Signals
The ReadyBoard 910 provides eight GPIO pins for custom use. The signals are routed to the CN13 header,
and the enable and initialize values are set in the BIOS.
For more information about GPIO pin operation, refer to the Programming Manual for the Super I/O
controller at:
http://www.smsc.com/main/catalog/sch311x.html
describes the pin signals of the GPIO interface, which provides a 10-pin header of two rows with
odd/even (1,2) pin sequence and 0.079" (2mm) pitch.
Oops! Jumper (BIOS Recovery)
The Oops! jumper 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,
forcing the BIOS to use the default settings. Connect the DTR pin to the RI pin on Serial port 1 (COM0)
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. Change the desired BIOS settings, or select the
default settings, and save 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
serial port DB9 connector at Serial Port 1, as shown in
.

NOTE
The ReadyBoard 910 requires an active heatsink (with fan) for the CPU and a
passive heatsink (without fan) for the PCH.
