I've read through many different threads and guides on this forum, all which have been extremely helpful, but I've gotten to a point where I'm just stuck, and I'm hoping someone can help.

I've got a Mini 10 (1010) with A11 BIOS.
I currently have OS X 10.6.3 running stably on it, but here's the problem:
I've had to remove the internal HDD and put it in a dock in order for OS X to recognize it. I installed the OS this way, and I can boot from the drive when it's connected with USB, but the minute I try and put it back inside the machine it won't boot.

I've already installed the AppleIntelPIIXATA kext with Kexthelper b7, but still no luck.

Would really appreciate any help on the issue. I feel like I'm so close.
