First, may I say that you should take it slowly and carefully. I saw your post asking for an installer and I'm sorry that nobody has come forward. Second, I assume you've followed the kit list for soldering in the install guide that I supplied. Anyway, to your questions.
1. About the Controller wires,in one place it says to connect the wires direct to the chip and the other to the alternative pointes.
Where do i need to connect them ( A,B,C,D,E,F,G,H,I )?
ANSWER: I earnestly recommend that you connect them directly to the chip. The vias (the alternate points) are deadly if you accidentally overheat one and it can zero the board if it sinks in. So take a razor blad and put it between the leg you are working on and its neighbour. Work from the razor side so that there is no bridge to the other side. If you use two razor blades, you might have a lighting problem!
2. How can i know the defrant between Bios with gap or not,i think i have with Gap.
ANSWER: The BIOS chip located as per the diagram will have 44 pins, 22 each side and a gap half way down.
3.Just to anderstand the connection area on the board, in the side of the Main board there are 4 chips.the first is the BIOS pointes M,N,O,P,Q,R,T,U,V,W ,the second is not conserned use, and between the third and the forth we have the connect points for the controller ( few of them on the forth chip).
About the RESET,GND,3.3 volt and scex are in the same side of the Controller and the Bios but behind the big all where the flat cable is.i know its sound strange how i describe it but i think you will understand, or hope.
Please tell me if i correct with the description about the position of the conection on the board.
ANSWER: I have to duck this question. I have never seen a v4 board in this way, only v5 and v3 (which I have documented). v4 will come! But my installer tells me that it is unambiguous from the diagrams as to chip location.
4. About the solder points on the Messiah for V4,how many do i need to solder,if i understand corect, it's three.
ANSWER: I'm not sure I understood you. There are 23 solder points on the Messiah as per the schematic.
5.If the connection of the wires are good,will i have any problems with the operation?
ANSWER: If you had a previous modchip, or your lens is dirty, i.e. if the laser is not in good condition, then DVD-Rs might not play. First clean the lens if this happens. Then you would have to recalibrate the laser by turning the DVD pot up by about/no more than 10%. There is a tutorial on
www. infofree.org. In my opinion (all my opinions are at your risk), there is a 90% chance that if your PS2 has not been abused, has not played DVD movies all its life and the laser hasn't been stressed, then DVD-R should work. You will have no other problems.
