hello again, sorry for the delay. i have uploaded fixed files etc and instructions on how to apply here:

http://sp4m.net/de2_web_fix.zip (http://sp4m.net/de2_web_fix.zip)

i have tested the tcp/ip performance with a simple echo server running on the board and a corresponding app running on my pc (connected directly to the board). i get about 550kb/s each way. with traffic going only one way from the board to the pc (just ack packets going the other way), i get about 3mb/s. the http server example works, but seems a little slow. i haven't looked into why this is. i have not tested dhcp, i'm using a static ip.

I have the ver 1.4a terasic code and have attempted in stall your patch; however, it does NOT seem to work with this version.

1) DE2_NIOS.V does not exist (DE2_WEB.V)

2) After making the changes the DM9000A interface nolonger has a 25MHz clock driving it. Therefre, it no longer works at all.

Any help would be appreciated.
