Compact Flash Master/Slave

The JCF1 jumper allows you to assign

either master or slave status to a com-

pact ﬂ ash card installed in the IDE#1

slot. You will need to connect compact

ﬂ ash power to JWF1 to use. See the

table on the right for jumper settings.

Watch Dog Enable/Disable

JWD controls the Watch Dog function.

Watch Dog is a system monitor that

can reboot the system when a software

application hangs. Pins 1-2 will cause

WD to reset the system if an applica-

tion has frozen. Pins 2-3 will generate

a non-maskable interrupt signal for the

application that is hung up. See the

table on the right for jumper settings.

Watch Dog must also be enabled in

BIOS (setting located in the Power

Menu).

Note: When enabled, the user needs to

write their own application software in

order to disable the Watch Dog timer.
