in the how to the pic is gone i think so ill just upload a pic (NOT MINE).
now just to fix the box you will have to solder a wire from that side of that resistor (R4D4). then solder the other end of the wire to the trace i highlighted in red on your picture here

it's a little harder than soldering to a pad so i don suggest this if your new to this stuff and this could be your last chance with the cpu-rst but if you think you can handle it scrape the trace, flux it, tin it, then solder a small wire to it, then to the resistor on the top side mobo.
