RTEMS is *not* linux :-)

There are no initrd/kernel images: the binary image that is loaded onto
a target is the result of linking an application (code you've written)
against the libraries you've just constructed by building RTEMS (i.e.
librtemsbsp.a, librtemscpu.a, etc)

I've used network-bootloading via Etherboot, loading from a floppy, and
GRUB to get my RTEMS applications running.

I don't have access to my GRUB config at the moment, but i'll send you
details when i'm able to. That may be your simplest option...

You may be able to achieve this effect by using the Qemu emulator (i.e.
launch an RTEMS application within an emulator running on your linux
box). Check the RTEMS wiki for information.
