Help me decipher the install diagram for modbo 745/Matrix Infinity 1.99 plz!

Ok, that's it, I'm about to give up. I bought a Matrix Infinity 1.99 - I have a SCHP-50001/N, v9 PS2. Now all I needed was the installation diagram how to solder. I've looked EVERYWHERE, I've asked the website I bought it from, I've asked other forums/website that talk about PS2 mods, and have been pointed to dozens of diagrams. A helpful chap also told me the mod 745 uses the same exact diagram. After tons of searching, I've found some for the Matrix Infinity 1.99/Modbo 745 or the v9 PS2. However, NONE are for the Matrix Infinity 1.99/Modbo 745 AND the v9 PS2! Except this one:

Am I slow? Look at the chip in the diagram, pretty much same as mine. But the chip DOESN'T have SCEX or RST. Just as well, the chip has an "S" and the diagram does not. If that's not enough, how come on the diagram there are TWO sets of B, G, I, and H? How can I solder one point on the chip to two points on the mobo?

Can someone tell me once and for all how to install this Matrix Infinity 1.99/Modbo 745? No one seems to really know. If I don't figure this out soon I'm just going to return it. Thanks for any help whatsoever.
