(Help me) Still waiting for root device

[espaçobine]

I had downloaded the Mac os X 10.7.3 Niresh12495 recorded the V2. Iso file to a DVD I pressed the boot "F8" and typed the command:

"Kernel Cache"=\amd arch=i386 -v

Then came this display screen.

 

Then I tried the command without "-v" and appeared

 

I read something about this error and said I would change in the system BIOS for the SATA AHCI mode. I tried to change, but in my mainboard was not possible. I even updated the BIOS, but nothing changed

 

If you can try to help me now I thank you.

 

Sorry for my bad English
