FULL EmpireEFI For AMD Processors
Sofia Gilcrease
For iOS, the boot process starts by running the device's Boot ROM code. In systems with S1 processors or A9 or earlier A-series processors, the Boot ROM loads the Low-Level Bootloader (LLB), which loads iBoot. In systems with newer processors, the Boot ROM loads iBoot itself. If all goes well, iBoot will then proceed to load the iOS kernel as well as the rest of the operating system.[5] If the LLB or iBoot fails to load iOS, or fails to verify iOS, the bootloader jumps to DFU (Device Firmware Update)[6] mode; otherwise it loads the remaining kernel modules.[2]
The best compatibility seems to be with Intel CPU's Using Intel Chipset's, Not that AMD CPU's won't work they will but they require a hacked kernal designed with them in mind and they are not recommended for OS X because of stability issues. Some Intel CPU's also have issues so I suggest you try and use an Intel 'Core Duo' or Intel 'Core 2 Duo' based machine (Atom processors also work) as others will not be nearly as stable and reliable. You also require a DVD Drive to perform the install and most video cards should work in VESA compatible mode but you may not have accelerated graphics. Other devices may not be recognized so you may not have internet access right-away. Lastly anyone who is planning on having a dual-boot system with Windows and the Mac OS should read the Dual-Boot section below to prepare correctly, click Here to jump to the Dual-Boot section
Offhand, I suspect that the problem lies with the CPU not being natively supported. It has been a while since I worked on this, but I seem to recall that the processors before the Core i3/i5/i7 line (including the Core 2 Duo) require some additional steps to make things work. Since virtualbox is passing instructions through to your processor with a minimum of modification, this is likely to be the issue.
