custom empire efi?

[jznomoney]

Is there a way to make a custom empire efi from inside of virtualbox? I want to try to make one for my motherboard. Does anyone have any insite.

I have a gigabyte GA-MA78GM-US2H http://www.gigabyte.com/products/product-page.aspx?pid=2995#ov

it is based off the 780g/sb700 series.
I also have a geforce gts 250, a phenom II 940 and 4gb of memory. I will also be installing to an IDE drive if possible from a SATA dvd drive.

Thanks in advance for an pointers you can give me.

So you are going to include Chipset kexts?

It is no problem you can use Mkext Tool by pcwiz to extract and recreate Extensions.mkext & the following command to rebuild the ISO:

sudo hdiutil makehybrid -o custom.iso yourfiles/ -iso -hfs -joliet -eltorito-boot yourfiles/cdboot -no-emul-boot -hfs-volume-name "CustomEFI" -joliet-volume-name "CustomEFI"

Does anyone know which kext I should possibly use for this board? And with the prebuild empire efi 1.085r2 I always get a kernel panic. I have tried to use cpus=1 but it still doesn't work. Can empire efi make it use a different kernel during boot that works?
