Hi... I'm still trying to install SL from a SATA>USB restored DVD partition from about 12 hours... I need some help, guys... just to make a step forward...
My situation:
1) Rampage II gene 0904 -> AHCI -> JMicron disabled
2) Restored a partition on USB disk with SL DVD -> installed Chameleon 2 RC3 on it -> replaced boot with PCEFI 10.5 -> added kexts and dsdt.aml from this 3d in Extra
3) Start booting from USB and everything works until the gray screen with mouse cursor..

I've tryed with -v -x32 but the only failed action was AppleSMBusPCI

Thanks everyone...
