I emailed the Kworld office in the US asking for some technical support. 
I would like to get a schematic of the board to figure out how things 
are interfaced with the 7135 chip. I got a response saying they are 
forwarding my request to an engineer. So that is at least something.

From what I read in the Philips documentation the 7135 the same as the 
7134 with a few extras. So we shouldn't have much of a problem. I am 
trying to retrieve the programmers guide for this series of devices but 
have not been able to yet. Does anyone else have a programmers guide 
available for the saa713x series?

Since the NIM (network interface module, the metal can) is the same as 
that used on the ATI HDTV Wonder board and several others we should have 
all the drivers necessary to get this board to work. The ATI HDTV board 
is fully functional I hope?

I will see what I can get from Kworld before I start to get creative. 
How do most go about writing a driver for a board. I mean how do you get 
the technical details necessary to make everything work? I guess if I 
need to figure out some deep dark secret that the windows driver does, 
then I can borrow a PCI bus analyzer from work but that shouldn't be 
necessary.
