ME Manufacturing Mode
Close JPME2 to bypass SPI flash security and force the system to use the Manufacturing
Mode, which will allow the user to flash the system firmware from a host server to modify
system settings. Refer to the table below for jumper settings.
VGA Enable/Disable
Use jumper JPG1 to enable or disable the VGA port using the onboard graphics controller.
The default setting is Enabled.
Watch Dog
JWD1 controls the Watch Dog function. Watch Dog is a monitor that can reboot the system
when a software application hangs. Jumping pins 1-2 will cause Watch Dog to reset the
system if an application hangs. Jumping pins 2-3 will generate a non-maskable interrupt
signal for the application that hangs. Watch Dog must also be enabled in BIOS. The default
setting is Reset.
Note: When Watch Dog is enabled, users need to write their own application software to
disable it.
