;-(((

Rumours were, that unfortunately the project got completely out of 
organization during 1995 (although some people still must have been 
working heavily on NWDOS during this time).  The patch sources might 
not be in the source control system but in other backups.  Maybe 
someone of the former NWDOS developers at Novell having personal 
backups???  Please, please, please could all the Ex-Novell people 
from Caldera contact other (Ex-)Novell people that have been 
working on NWDOS during 1995 to track down where the patch sources 
are left.  IMHO, we definately need them for the progress of OpenDOS, 
at least for the kernel, the resident system extensions, and the 
memory managers.  We don't have the time to rewrite a full year's 
work from scratch.  By now, we should have been at a point, where to 
look in the future, but at present we're bound to loose time in some 
kind of 'idle cycles', searching for the necessary remaining patches. 
The work has already been done, why should we have to do it once 
again...  (I can see Billy ROTFLHAO...) ;-(

Yes, but I first meant optimizations by e.g. reducing redundancy 
in the IBMBIO.COM code.

I really would like to provide this info, but all I have are the 
HISTORY logs, the update binaries, a fair understanding of DOS 
internals, tools like IDA, SOURCER, DEBUG, and FC, two hands and 
a brain, but I would need a day having 48 hours... 
This way, finally we could hack out the patches for all binaries that 
have been written in assembler, but it is even more complicated (if 
not impossible) to do this for files, written in higher languages 
such as C.  Someone knowing of a DOS text-editor with some kind of 
auto-sync/lock feature when comparing two source code files in 
different windows (not only that scroll-lock feature of TSE)?  
Also should be capable of handling filesizes of 500 KB and more...
