Hi, I'm trying install Snow Leopard (retail DVD ver. 10.6.3) using iBoot 3.3.0 in my HP/Compaq dc7900 SFF
I'm using boot flags -v -x to Verbose mode and safemode. But when the installation screen comes the USB ports not working, any of them. I was try several combination of boot flags with the same result. I attached print screen of the loading where I can see an constant failure, something about "AppleUSBUHCI.......Start unable to initialize"

I did a search, no find anything help.

Check that you have the latest BIOS update :

Yeap, before start this project I updated the BIOS to the last version.

Remarkably, in one of the attempts did work, I managed to do the installation, delete the AppleHPET.kext and everything worked correctly, but during the installation of devices make a mistake and after a restart, the system would not load. I tried to reinstall the operating system and is where I am detained without progress, Back to square one.
