The default setting is Enabled.
ME Manufacturing Mode Select
Close JPME2 to bypass SPI flash security and force the system to use the Manufacturing
Mode, which will allow you to flash the system firmware from a host server to modify system
settings. Refer the table below for jumper settings.
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.
BIOS Recovery
Use jumper JBR1 to recover the BIOS settings. The default setting is Normal. See the table
below for jumper settings.
