Hi Roger, Mats & Kristian...

Your "bad english" is better than most native speakers ;-)

Getting out my little "cheat sheet" I have drawn the jumper
configuration for the ATMega48/88/168 series...

1. Jumper "Prog Ctrl" to "Port D"

2. Jumper "Prog Data" to "Port B"

3. Single wire jumper from BSEL-2 (pin toward power connector side) to
PORT-C pin 3 labeled PC2

4. Shorting jumpers on P-JUMP (two of them) ... place so they are
parallel to the long edge of the STK500 board.  (hard to describe!)

5. You should have shorting jumpers on VTARGET, RESET, XTAL1 and pins
1-2 of OSCSEL.

Use socket 3200A2 (green) for your chip.

In AVR Studio, besides setting the correct COM port, not much to set
other than make sure you have the correct chip ATmega168 selected.

Hopefully that will get you going.  All this information is buried in
the help sections of the Studio program -- but it is rather disorganized
and confusing even to one who has used it many times.

The ATMega168 (and its smaller brothers) are very neat microcontrollers!

Best of luck,

Don
