Until now my only RTEMS targets have been the Motorola MC68360 and
MVME167. Now I'm moving to the wonderful world of x86 hardware. I'm
using the RTEMS pc386 BSP with GRUB to build a boot floppy. I've been
able to run the RTEMS hello and ticker tests with no problems, even when
I put a compressed image on the floppy. But when I try to boot a really
text data bss dec hex filename
1177613 57911 123360 1358884 14bc24 bin/RTEMS-pc386/example
which has been stripped and compressed before placing on the floppy, I
get the following message from GRUB stage2:
Loading below 1MB is not supported.
Howcome smaller programs work, but big ones don't?
Am I running into some problem causes by the stupid 640k memory boundary
on a PC?
