Anyone booting RTEMS from MS-DOS?



I'm trying to run the "Hello, world" application using the pc386 BSP.  I
have a single board computer with built-in Flash.  The board currently
boots into MS-DOS.  I tried following the information in
http://www.rtems.com/wiki/index.php/Pc386#Booting_an_RTEMS_Application
for using Luca Abeni's eXtender but end up with the following error:

C:\RTEMS\PC686>x hello.exe

MultiBoot Loading

MultiBoot ELF

Elf Loading.Error : (X_ELF) Kernel starts before Extended memory top

Exec_space=0x110000 Needed Memory=145216 bytes - Kernel starts=0x100000

.

Elf Loading.Error : (X_ELF) Kernel starts before Extended memory top

Exec_space=0x110000 Needed Memory=145216 bytes - Kernel starts=0x100000

.

Program loading failed!



This happens with the pc386, pc386dx, pc586, and pc686 BSP's.  Anyone
have a suggestion?  I don't plan on using MS-DOS in the final
application but I don't have enough experience with grub to try to
figure out how to get grub onto the internal flash.

The actual target hardware is a Kontron AM4002
(http://us.kontron.com/products/boards+and+mezzanines/advancedmc/process
or/am4002.html) with 2GB of Flash, apparently connected to look like
IDE-connect CompactFlash.
