Bob, thank you very much for doing this!  I downloaded the PDFs of the 
21143 last week to get an Asante card with a 21143 to work with Etherboot 
(it doesn't have a ROM socket, unfortunately, but knowing that it works 
from floppy would be good).

The Etherboot tulip.c driver doesn't support 100BaseTx with DEC21143 at 
all, to the best of my knowledge.  There are comments in the code that 
suggest that SROM/MII support was not finished.

I added support in ntulip.c for several 10/100 tulip clone cards, 
including the MX987x5, the LC82C115 (aka LNE100TX), and the LC82C168 (aka 
FA310TX).  They don't have SROM, so media selection is simplified.  I was 
about to see about integrating the Linux SROM parsing code to handle 
21143-like boards.

Ken's the maintainer, but I will certainly be happy to test your patch, 
and see if it works with my AsanteFast 10/100 card.  

Thanks again for your efforts!
