does the log show any other result than 0xff/0x00 (for any chip, if you
probe for all of them)? i think you have not posted a log for that one,

no, i aborted after entering the loop. the enable method is executed at
startup of the programmer... hm. maybe it gets reversed since then.
carldani added some kind of roll-back mechanism where the code
registers certain actions in init functions etc. that are reversed on
shutdown. but i think ctrl+c just aborts anyway...
after looking at the code... the comments in nicintel_spic.c explain
that the roll-back thingy is not possible, but it does it manually in
the shutdown function, but i am quite sure that this is not called at
all when you abort while probing... so it should be ok. *shrug*

that was my motivation too... and that's not a very strong one ;)
