read network conf from sd

i'd like to know if it is possible to accomplish this:

  • copy a text file into a sd card with some network settings (ip, mac, gateway)
  • read the file at arduino boot
  • use the configuration read to setup the ethernet communication

if it possibile, have you any link to point me in the right direction?
Thank you

Yes, I do it. Here is the basic code.

Thank you so much! karma+1
