Tried to get your library working for me, but i didn't manage.
I'm using PIC18F4520 and tried udp send, but it seems the program does not get past Eth_Init_(PORTC, 1, 0). The last thing i see on the display is "set parameters done".
I'm using an 8Mhz cristal and run the pic on 32Mhz so i changed the TMR2 postscaller to 8. i tested the delay and is exactly 5seconds, so config word and clock speed is ok...
tried MASTER_OSC_DIV64, MASTER_OSC_DIV4, MASTER_OSC_DIV16..never gets past Eth_Init_(PORTC, 1, 0).
If I don't connect anything to the ethernet port of the ENC, should the lib get past Eth_Init_(PORTC, 1, 0) ? Or can my network hardware also be the problem?

end.I'm going to get a 10Mhz crystal soon, i hope that is the problem.
thanks for any ideas.

GREAT WORK
