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 ?

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. -- ------------------------------------- -- Merge vertically for real address ------------------------------------- s n p @ t . o k i e k c c m -------------------------------------
