Problems getting started with PC686 BSP

I've been trying to get the hello_world example to work on a Dell laptop
without success.

I've tried with RTEMS source from CVS head and with RTEMS source from
rtems-4-10-branch (in case CVS head had a problem on the day I
downloaded).

I've tried using tools I built and tools installed from .rpm on two
different CentOS 5 x86_64 machines.

I'm using a USB boot from a flash drive (the laptop doesn't have a
floppy drive).

I followed directions from a web site to build a bootable USB drive with
GRUB.  GRUB (0.97) loads and displays the expected menu of selections
from the grub.conf file but none of the three files I try to boot work.
The .ralf is reported as "Error 13: Invalid or unsupported executable
format" and the .exe files leave the laptop with a blank screen.

My grub.conf is:

default=0
timeout=15
title RTEMS pc686-tests-hello.exe
        root (hd0,0)
        kernel /boot/images/pc686-tests-hello.exe
title RTEMS pc686-hello.ralf
        root (hd0,0)
        kernel /boot/images/pc686-hello.ralf
title RTEMS pc686-hello.exe
        root (hd0,0)
        kernel /boot/images/pc686-hello.exe


The file pc686-tests-hello.exe came from
/opt/rtems-4.11/i386-rtems4.11/pc686/lib/rtems-4.10/tests and
/opt/rtems-4.11/i386-rtems4.11/pc686/lib/rtems-4.11/tests after
installing the RTEMS I built and running "make install".

The files pc686-hello.* came from building the hello_world examples.


My USB drive contents are:

Can someone send me a clue as I apparently don't have one?
