* don't have access to, one can specify an LED type, which allows
* you to enable/disable a particular LED amongst many. On my Sun
* Fire 4140, it appears to do nothing and affect nothing. I will
* add in a new option later if it becomes necessary for the user to
* specify an LED type. In the meantime, I will copy the code use
