Greetings, all,

This is a summary of the responses I received to my posting about 
using a 3Com 3C905 PCI Ethernet card in an Ultra 10 (original message 

Apparently, the 3C905 is meant only for Intel-based systems and not 
for SPARC systems.  It was worth a try since it was lying around, but 
it appears that the group will need to purchase a Sun PCI NIC.

I did receive pointers to some web sites that could have useful 
information.  I have not had a chance to check these, yet.  For the 
record (and for the benefit of anybody who finds this message in the 
archives), they are the following:

Thanks go to the following for very prompt and informative responses:

I appreciate everybody's time.
