fix broken track + what's point Q's function?
After messing about with a DMS3 installation I've been attempting for a few days now, I took everything out last night and managed to find a TINY bit of solder on the chip (not sure which one it is - the one with point D/E on it.
After managing to remove that and testing the PS2, I continued to try and install the modchip from scratch. This was at about midnight so I was getting rather tired, and for some reason my soldering iron seemed to stop working so i turned up the heat, and managed to pull off one of the pads on the underside of the motherboard. It's point Q that has been pulled off... and most of the track along with it. If you follow the track from point Q, you find a little circle... well, the track is off the motherboard from just below the chip above it, right to that little circle.
I'm actually wanting to know a few things:
1 - What does point Q allow the modchip to do? (what data is transferred over the track that passes Q?)
2 - To fix this, I have the idea that I just (try to) attatch a wire from the track just visible under the chip (assuming i can actually get some wire to stick to the REALLY thin track) to the little circle?
3 - If I can't get the wire/solder to stick on the small/thin track, is there any other point I could attatch this to? - I wouldn't really expect to find another point, as the track goes under the chip and I'd assume that it needs to carry data to the chip itself.
