== Ethernet desoldering == I attempted to desolder the RTL8139DL chip I had broken earlier. Even with a large amount of flux and 40 minutes of hot air rework at various it didn't come off, instead making a flux mess and possibly damaging the board. I tried again the next day, changing my technique to use a larger nozzle, putting the nozzle closer to the chip and using tweezers to push the chip upwards to try and defeat surface tension. It worked! I prepared to re-solder the 6 lost pads, belonging to the following pins: * GND * AD21 * AD20 * AD17 * IRDYB * TRDYB Only to find out only AD17, TRDYB were visibly connected. It's unclear where IRDYB connects, if at all.
