Watch Dog

JWD controls Watch Dog, a system monitor that takes action when a soft- ware application freezes the system. Jumping pins 1-2 will cause WD to reset the system if an application is hung up. Jumping pins 2-3 will gen- erate a non-maskable interrupt signal for the application that is hung up. See the table on the right for jumper settings. Watch Dog can also be enabled via BIOS.

PCI-X Slot Freq. Select

Jumpers JPX1A and JPX1B on the H8DMR-82/H8DMR-i2 can be used to change the speed of PCI-X slots 6 and PCI-X slot 7, respectively. See the table on the right for jumper settings.

Note: JPX1A controls the speed for PCI-X slot #6 and JPX1B controls the speed for PCI-X slot #7. The default setting for both is Auto.

The JI2C1/2 pair of jumpers allows you to connect the System Management Bus to the PCI expansion slots. The default setting is closed (on) for both jumpers to enable the connection. Both connectors must be set the same (JI2C1 is for data and JI2C2 is for the clock). See the table on right for pin defi nitions.
