I am referring to the use of two 10/100BaseT Quads with Solaris and not the
old 10BaseT Quad.
My Source is the Product Announcement Information on the "Sun Quad
FastEthernet SBUS Network Interface Card (Q1CY97 #49). I enclose an excerpt
from the Question and Answers section (without permission from anyone).
QUESTIONS AND ANSWERS
---------------------
Q. How many cards can I put in a system?
A. The system should have one CPU per FastEthernet port on the QFE card
(i.e., 4 Ports equal 4 CPUs). This provides the highest speed
performance possible.

I have also installed multiple 10BaseT Quads without too much of a
a performance impact. However, I have not had the oppurtunity to test
multiple 10/100BaseT Quads :(( as yet.
