           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.
