I am trying to run the Genode(12.08)/NOVA demo as a boot option under Legacy GRUB following the "official" Genode instructions. When GRUB executes the line "module <path>/core", it halts with Error 16 as in the subject line. Also if I use full paths, no symlinks. When I edit the Genode Demo entry as GRUB runs and delete everything below the "kernel hypervisor" line, NOVA loads, reports 2 cores, and halts because "no ELF". "file core" reports that core is a 32 bit ELF. I have successfully run the Genode demo on top of Ubuntu 12.04 LTS and the Genode/NOVA demo on top of Ubuntu 12.04 LTS. GRUB savedefault is false. I tried the patch to stage2/fsys_iso9660.c with no luck. I have used both an IBM ThinkCentre and an HP laptop (6530b) with both Legacy GRUB and Legacy GRUB with Trusted GRUB patches. "The Google" is out of suggestions. Thank you.
