need help - REALTEK gigabit ethernet datasheet for RTL8169 series wanted

Hi,
I am planning to write an WINDOWS NDIS 6.0 driver for any of the
latest cheap gigabit ethernet cards for self-learning purposes.
STARTECH.com and hawking 32-bit PCI cards seem to implement this
realtek RTL8169 chipset. I happened to see a open source driver for
this in LINUX. Hence, I am appealing to the LINUX community, where
someone might have access to datasheet for this, providing the register
level details.

Can you email it to me at kernwind@yahoo.com

thx in advance
ugk

P.S realtek website does NOT provide one
