QEMU and RTEMS problem on Ubuntu

[JiSheng Zhang]

I have tried to build floppy image myself as I did two years ago but
failed, this is the error message which grub-setup prints:

IMHO, there's a lot of bugs in grub2 now. So it's better to use grub, it is OK

I got the same results when using the img form Chris Johns
