Clear CMOS Operation
The following table indicates how to enable/disable CMOS Clear Function hardware
circuit by putting jumpers at proper position.
JP7
Function
Off Normal
Operation
★
1-2 Short
Clear CMOS contents
To correctly operate CMOS Clear function, users must turn off the system, move JP7
jumper to short pin 1 and 2. To clear CMOS contents, please turn the power back on
and turn it off again for AT system, or press the toggle switch a few times for ATX
system. Move the JP7 back to Off (Normal Operation) and start the system. System
will then produce a “CMOS Check Sum Error” message and hold up. Users may
then follow the displayed message to load BIOS default setting.
3.5 WDT
Function
The working algorithm of the WDT function can be simply described as a counting
process. The Time-Out Interval can be set through software programming. The
availability of the time-out interval settings by software or hardware varies from
boards to boards.
ROBO-6710/6730 allows users control WDT through dynamic software
programming. The WDT starts counting when it is activated. It sends out a signal to
system reset, when time-out interval ends. To prevent the time-out interval from
running out, a re-trigger signal will need to be sent before the counting reaches its
end. This action will restart the counting process. A well-written WDT program
should keep the counting process running under normal condition. WDT should
never generate a system reset signal unless the system runs into troubles.
