blazingeagle2c,I want to stay with the "jumper" aspect of this just because in my case there were other contributing factors re the "external cases'. I actually had 3 ,all the same make,all new.Of the 3 only 2 would work with the pin configuration as stated by the case mfg. Wouldn't you know the 1st one that i tried when i set the jumper pins was the one that DID NOT work. Of course that caused me to question the jumper solution. Fortunately i tried the other 2 and they both worked (and continue to work).I say this only to apprise you of my own experience in case it leads to solving yours.If you have not contacted the case mfg. i urge you to do that if possible.truenorth
