               PREMMIA LX WITH 3COM ETHERLINK II RUNNING BANYON VINES

    PROBLEM:       Error occurred when running a Premmia LX with a 3Com Etherlink
                   II 16 bit card (3C507TP) on a Banyon Vines 5.53 network.  When
                   Banyon attempted to enable the 3Com card, garbage appeared on
                   the screen.  Various I/O address Base address and Interrupt
                   levels were tried to no avail.  Also, the 3Com diagnostics did
                   not recognize the card when it was enabled and running the
                   "Internal Testing of Adapter" program.  It did recognize the
                   3Com card when EMM386.EXE was removed, but it still did not
                   work with Banyon.

    CAUSE:         Firmware corruption on the 3Com 3C507 Ethernet adapter.
