You need to be sure.  It's hard enough to try guessing what the problem may
be, to make it even harder this way.

Try:

diff -ur grub2/kern/i386/pc/init.c tmp/kern/i386/pc/init.c
--- grub2/kern/i386/pc/init.c   2008-01-23 12:25:52.000000000 +0100

   if (! grub_os_area_addr)
     grub_fatal ("no upper memory");
+
+  grub_printf ("%p\n", grub_boot_drive);
 }

 void

this will also tell you the grub_boot_drive value (let us know).

What version of GRUB Legacy did you install in that system?  Did you modify
GRUB Legacy when you installed it, or something like that?

Does a recent GRUB Legacy install work on that board?
