Hello Forum

Im new here and from germany (so sorry for my bad english).

Actually I have installed Snow Leopard on my Notebook. I reached this, because i used a boot CD and the command: EHCIacquire=yes.

Now i want to install Mountain Lion. I created an external HDD to install ML. To succesfully reach the ML Setup I have to use the following commands: EHCIacquire=yes PCIRootUID=0 npci=0x2000. I also tried rd=disk0s1.

But in the Setup there is not shown my internal SATA HDD (also in Disk Utility).
In Bios there is no option for AHCI and its the newest version.

Why Snow Leopard Setup could detect the HDD and ML not ?

I also tried an installation via myHack, but the same result.

You can take my Notebooks technichal data from the signature.

Can / Do you want to help me?
Im really looking forward to your answers
Thanks alot !
