13211	EFI is broken for RAM amounts above 3456MB RAM at 32MB VRAM in 64bit Mode	Lars Sonchocky-Helldorf		"When trying to assign more than 3456MB RAM to a Mac OS X Server 10.6.8 guest in 64bit Mode running on a Mac OS X 10.6.8 host the EFI won't initiate the boot process properly. I observed different behaviors depending on the amount of RAM and VRAM I assigned:

- Up to 3456MB RAM at 32MB VRAM or 3328MB RAM at 128MB VRAM everything runs fine
- When assigning 3457MB RAM at 32MB VRAM I get an ""No Mapping Found"" Error in the EFI and drop back to an EFI shell
- For higher amounts of RAM (like 3500MB RAM at 32MB VRAM) I get only a black screen that changes in size several times

Please have a look at the attached screen shots and logs.

I need to run a Mac OS X Server 10.6 guest inside Virtual Box for some serious work: I have lots of Adobe Freehand documents, Adobe Freehand was obsoleted by Adobe, there is only a PowerPC version of it. Mac OS X 10.6 is the last version of OS X which support PowerPC binaries through Rosetta Emulation. That means I am stuck with 10.6 but I need to update to 10.9 to run other software like Final Cut Pro and Pixelmator. So the only way to go is to keep Freehand inside a 10.6 guest while updating the host. Sadly having less than 4GB of RAM for the guest is not enough. I appreciate your help very much!"	defect	closed	EFI	VirtualBox 4.3.14	fixed	EFI RAM		OSX Server	Mac OS X
