Hello Mr. Yap !
Is it possible for you email the docus you have. I have to port/
deveop a driver for the 82559ER for an other UNIX-like system
and the way with INTEL (non-disclosure agreement) is ongoing,
but take a while. But I will start now.
Is it possible for you to send me things, like Developer's Software
Manual and other important things. In the basics of the 82559 and
82559ER are identical....
ith friendly regards
Christoph Plattner
