+Run the emulation with:
+
+ qemu-system-m68k -M q800 -kernel output/images/vmlinux -nographic -drive file=output/images/rootfs.ext2,format=raw -append "root=/dev/sda console=ttyS0"
+
+The login prompt will appear in the terminal that started Qemu.
+
+Tested with QEMU 2.4.0 from https://github.com/vivier/qemu-m68k
+You need following branch: q800-v2.4.0
