Robert,

Yes I found that part, and thanks for the help. It was as I suspected.
The rel.asm that I have is very different.
--
Screen comes up w/ blue background, white lettering & white border.
Then it goes to another screen with the black letters/green background
before it goes to /term, the one that displays the "sysgo" msg.
Where does that one come from? (/W ?).

Thanks,
Paul - idezilla
