Help with magic 3 instalation in v3

[Londo Mollari]

hi all, first sorry for my bad english :D

I need some help, a friend and i installed two magic 3, the first in a v7, works fine, load all games etc. The second magic 3 we installed in a v3, you know that the soldering points are very dificults, afther many hours the modchip work, load ps1 backups and originals too, play DVDmovies, and load ps2 CD games, but don't load ps2 CD backup (the same backup that's work in the v7).

my question is: Exactly wich points are the ones who send the signal to bios, to corfim that the cd is a ps2 game?

We inspected all the soldering points, and they are fine.

I know that: the s point is for ps1 signal
What point is for ps2 signal?

Thanks for your help.

afther many days looking in many forums i don't find nothing that can help us, but i think that meyousikmann pointme in the correct way to solve the problem. I see that there a many comuns point in the install of messiah2 and magic 3, in a v3 non-gap. That points are soldered in the bios and in messiah2 install they are named M, N, O, P, V, U, T, Q (the same letters that in the magic3) that are conected in the pins of the bios. I have a v3-gap (and the bios is in the underside of the motherboard) and for magic3 that same points are soldered in via points near of CD/DVD controler, but in the diagrams of the messiah2 are soldered direct in the pins of the bios (that is underside of motherboard). I think: if the v3 non-gap have the same points for the two chips (magic3 and messiah2) probably with my v3 gap i can use the same point that messiah2 and conected direct in the bios underside of motherboard. I compare the points of magic3 and messiah2 in other version of ps2, and i find the same comuns points. I think that the makers of messiah belive that the via points (for v3 gap) are not good.

In the case i'm rigth, what's doing that points (M,N,O,P,V,U,T,Q)?
They tell to the bios that the inserted disc is a ps2 game?

I don't try to soldered that point direct to the bios because i'm probably wrong, but i'm not sure.

Can some one tellme what function make that's points?

Thanks for your help.
