Executing samle RTEMS application on QEMU

[Gedare Bloom]

Different grub versions might start numbering the drives at 1 instead of 0.

I don't recall off-hand, but I think there is some way in the grub
command line to get some listing of what the drives are. I would try
(hd1,1).

Other than that, we don't know what QEMU version you run, don't know
which toolchain you downloaded (it must be one of the mingw?), and
Windows XP is pretty old so it is hard to say for sure if your
software stack even builds properly. Unfortunately, not many people
will be testing with what you are using. You might consider using a
virtual machine with Linux, or even installing a Linux Distro on a
partition of your computer if that is possible.

If the problem is not with grub but is with RTEMS booting, then you
should try to hook gdb up to qemu so that you can see what is
happening.
