hi, I followed your method and exact pinning as written in first post by admin. I tried many times but i get this message from the software: ***CPU and JTAG communications check*** ERROR: communication with LPT/JTAG ERROR: register test failed Check your JTAG/LPT1 connection and/or adjust your voltage regulator Have you any idea what is happening? I became sick checking and checking all day, but nothing's wrong.
