I2C Bus for VRM
Jumpers JVRM1 and JVRM2 allow the BMC or the PCH to access CPU and memory VRM
controllers. Refer to 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, the user needs to write their own application software
to disable it.

JPB1 allows you to enable or disable the BMC (Baseboard Management Control) chip and
the onboard IPMI connection for debugging purpose only. This jumper is used together with
the IPMI settings in the BIOS. After the BMC is disabled, IPMI health monitoring and remote
management functions are no longer supported.
