I've been trying massive numbers of installs to no luck unfortunately I've gotten somewhat far with a retail SL disk but I hang up on AppleUSBOHCI[(0xstring that varies)]::CheckSleepCapability - Controller will be unloaded across sleep and then still waiting for root device endlessly. I tried using a kext to fix the still waiting for root device but that led to a CPU halted error. DSDT patching fails also when I tried it from inside Leopard Force compile emits 175 errors. I've also tried using a 10.6.2 Patched release but that always kernel panics when the installer tries to reboot and loading the os again gets stuck on the appleusbohci/root device error. Anyone have any luck with this system or one with similar specs?

Basic Specs are as follows

Foxconn A7GM-S (RS780 Chipset SB700 Southbridge)
AMD Phenom 9750 X4
ATI Radeon HD 4650

Are you running with AHCI enabled?

I got it all straightened out using AHCI finally, I was on IDE until I tried AHCI and finally got it up. The only problem I have is that my apple keyboard won't work properly but I'm not concerned about that
