What is in the first 6 bytes of the BDOS (before the entry point). 2. What significance is attached to the 4 addresses after the BDOS entry point (after the initial jump). What services are performed by the subroutines pointed to by these addresses. If this discussion has gone on before, I am sorry, just point me at the archive files are I will try to catch up. If there is a document available with with the answers, just point me. I got started on these questions after watching a popular directory lister (XD or SD) go south for the winter with a spooler overlay in place, and found it using these secret addresses. Thanks Bomberger@office-3.
