Come to find out, if you have a customer who replaces his/hers vmpro server,and if they had a license dongle that was Parallel,and if the new server for vmpro does not come equiped with a Parallel port and the cust goes out and buys one. The license dongle will not work on the newly installed Parallel port. Speaking with the hardware guys you will need a pciX extender to give the Parallel card full functionality of the Parallel port. So don't sell the Parallel dongle.
