guys i,ve done 3 of these now and had problems with the first one with the dvd controller points and the ps2 would only boot ps2 backups

guys its boots every ps2 i,ve put in so far fine
very easy install lads as i cant solder to bios pins

but i advise anyone who does not have the right equipment and experience to do a full 23 wire or 24 messiah to go for a clipkit because failing that you,ll goose your ps2

guys get flux spray or flux pen
solder paste
and precision blade set

and you,ll do these no probs if you got patience

all the best

and cant wait untill the messiah clip kit is on sale
