You have to make sure AvrDude knows about your PARTICULAR cable wiring.  If
you look in "avrdude.conf" the required information should be really
obvious.  Avrdude is very nice in that way.

There are lots of parallel cable programmers out there and for some reason
they all seem to use a different connection scheme.

Subject: [AVR-Chat] Re: AVRdude - initialization failed




Since I am using a parallel programmer, and I already used it with
AEC ISP software to program AT89S8252, I am sure it works fine (it
just a cable that connects MISO, MOSI, SCK, RST and GND to the
parallel port).
I checked continuity from the DB25 connector to the ATmega16
programming pins, and everything is ok.  Also, I verified the power
(5V).
I will check again the board circuit and the parallel port
configuration.

Regards,
Jose

Maybe also your reset pin since the programmer needs to pull reset
to ground for 20ms.
