AVR-Chat

I created a programmer definition in avrdude.conf.  I
am using Win XP, and have had to start giveio.sys to
make AVRdude to access the parallel port.  The pins
that I've used on the DB25 connector are 5,6,7 and 8
(GND is on pins 18 thru 25), so my programmer is
similar to the one you use.

I saw some articles about AVRdude and PPI programmers,
and they say that sometimes brand new AVR chips have
problems with fuses configuration so microcontroller
can not enter programming mode.  I have to try using
"-v" option to see data transferred.

Another possible problem would be the parallel port
configuration.  I will try the following:
Start -> Settings -> Control Panel -> System ->
Hardware -> Device Manager -> Ports -> LPT1 ->
Properties -> disable "Legacy Plug n Play Detection"


At this point I think the cause of this problems is
fuses configuration or parallel port configuration.
