Supertimer, Yes, the control panel was set to YOUR CARD. I hadn't seen the post on removing the first bank of SIMS. I did not get much doc with the card. There are 5 sets of 3 jumpers on the front of the Sirius card. Do any of these jumpers need changed if the SIMM is pulled? Do you have any idea what these jumpers control. Thanks for your help.
