I have only one HD wich has partition with Leopard 10.5.8 with Boot 132 and Chameleon for HDDrivers (this one is without graphic interface), and another partition wich I just installed a Snow Leopard from SnowOSX, I already patch DSDT, but when I'm trying to boot Snow Leopard with choosing that partition, nothing happend. The cursors spin for a wile and black screen.

What I did wrong
