It is quite possible to use GNAT/RTEMS on this target.  There is a
very active RTEMS submitter who has an embedded i386ex target with
networking.  He has encountered few problems except for the lack of
harward floating point on the i386ex. :)

We call this BSP the pc386.  It treats a PC as an embedded target. On a
standard PC, you can boot your application from floppy or via netboot to
avoid clobbering windows or Linux.  On an embedded PC, you can arrange
to boot from Flash.  As you might expect, there is a lot of activity
centered around this BSP.

You can use numerous OSes as the host. Most people seem to Linux,
Solaris, or cygwin.

Feel free to ask questions on the RTEMS mailing list at OARcorp.com.
