try pressing the eject and power button really really fast, although, I don't think that will do much. Just worth a try. Maybe that 3 seconds is actually a .5
Anyways, I never installed one of these chips and just now got a glimps at the solder instructions. The d1 probably controls the boot or it is another ground (heh, didn't look like the screw was used), so make sure you have enouph solder there, or that it isn't touching any other points. Also check for solder spots on the board, maybe some solder dripped. If the other chip acted the same, it has to be the points on your mobo. You might also want to try a different wire. It's unlikely, but that could be the problem.
If all fails, I guess a switch on the d0 will be your only option.
