    YES.  The system will never display the warning message while system
boot up or
    media changed.

  Do you modified the following lines in tulip.c(v.90f)?

1372c1372
<           tp->csr6 = 0x814C0000 | (tp->full_duplex ? 0x0200 : 0);
(new)

  Could you tell me how do you measure the performance and your testing
environment ?
I would like to simulate it. Thanks.
