I am interested in installing a memory card reader in my XW4550 Workstation in the floppy drive slot. Anyone have info on this operation? HP does not list a unit for the XW.There are several card readers on ebay that are listed for the Pavillion desktops. Will these units connect and operate in my XW desktop? In looking at the wiring for the motherboard, I can not locate a socket to connec the cable from the card reader to the motherboard.
