Watchdog Timer
Watchdog (JWD1) is a system monitor that can reboot the system when a software application
hangs. Close pins 1-2 to reset the system if an application hangs. Close pins 2-3 to generate
a non-maskable interrupt (NMI) signal for the application that hangs. Refer to the table below
for jumper settings. The Watchdog must also be enabled in the BIOS.
TPM Enable
Use JPT1 to enable or disable the onboard TPM 2.0. Refer to the table below for jumper
settings.
Audio Enable/Disable
JPAC1 allows you to enable or disable the onboard audio support. The default position is on
pins 1 and 2 to enable onboard audio connections. Refer to the table below for jumper settings.
ME Manufacturing Mode
Close pins 2-3 of jumper JPME2 to bypass SPI flash security and force the system to operate
in the manufacturing mode, which allows you to flash the system firmware from a host server
for system setting modifications. Refer to the table below for jumper settings.
