synogeek: No, this card is here to stay; it gives me USB 3 and UPS compatibility support, plus I was not using the PCI slots.
ordimans: Thanks for the links. However the post is old and refers to a lower DSM version. Unless someone posts the procedure for microservers and DSM 6, I would not want to break my install and lose access to my files.
In short: if you have a free PCI slot, that card is not expensive and WORKS!!. Now I can wait for a new boot procedure for 6.1.
