+
+Through modify buttons' property "Enabled" to disable/enable
+corresponding button.
+Currently support power and reset button.
+
+Test-By: ipmitool raw 0x0 0xa 0x2 //disable reset button
+         ipmitool raw 0x0 0xa 0x1 //disable power button
+         ipmitool raw 0x0 0xa 0x0 //enable all buttons
