QEMU/GRUB: No multiboot header ,found

Dear all,

I have installed all the RTEMS tools on Windows, compiled RTEMS 4.9
(--target=i386-rtems and bsp=pc386) and installed QEMU as detailed in:


All these operations went well.

Therefore, I have tried to launch some RTEMS applications by means of
QEMU/GRUB (in this phase I have taken the executable files produced
during the RTEMS compilation phase, placed in /testsuites/samples): this
operation was successfull as well.

After that I have compiled successfully Hello Word by myself
) and put my hello.exe in the folder /testsuites/samples/hello).
With my Hello Word, the GRUB gives me the message "No multiboot header

As far as I have understood, my hello.exe does not have a multiboot header.
How can I overcome this issue? Should I modify somehow my source code or
the makefiles in order to create this multiboot header into my .exe?

Thanks in advance

Massimo Tipaldi
