Re: An OS in Ada, why not RTEMS ?

That could be problematic. This would suggest that one
has to keep several versions of Gnat current would it not ?

Ok, but still not sure why that would preclude RTEMS as a 
starting hack point ...

Your other issues noted. On the whole, it would be more fun 
to keep hacking away at EduOS-Ada, but why, as you say, 
re-invent the wheel ?


On, your final thought ...

I know you have looked at EduOS-Ada, so is your main 
interest in just getting a boot into a "Hello World" 
type Ada main without all the other stuff ?

If so, I have a stripped EduOs-Ada which boots from 
"init.asm" still, but does nothing but throw bytes at 
the video addresses to produce a text splash screen.
If this would help you to keep going, let me know.
