triple speed ethernet without external memory

Thank you very much for support, with ref. to Nios II Ethernet Standard Design Example, I removed CFI controller and Tristate bridge and inserted onchip ram in place of DDRx, compiled in Quartus II. Created simple socket server project in NIOS II eclipse (with above sopcinfo file), when I was building the project, got some errors (related to Flash memory), then editted and commented Flash related code lines. Now, it is working (with telnet commands able to toggle leds). I will modify this code for my application, if, I find any difficult, get back to you.
