What about yours?

What are you booting RTEMS from? How did you create your grub

If you can build the example/hello, then it is OK and there
is just a discrepancy between the executable format produced
and how you are booting it (grub version, setup, etc?)

bin2boot converts it to a netboot image.  I do not know the
relationship between that and a multiboot image.

I am running ELF files from a qemu vfat.  I use the .exe files.
