My NVIDIA 7800GT fail to change mode under NDN (other than 80x25), I
have no idea and don't know how to make it work.

I don't think that kind of high-end card can't do this kind of simple
task, just don't know how to enable it.

Does it change using regular dos commands?
mode co80,50
mode co80,43
test without NDN loaded, because it has an option to restore it's own 
display configuration.

The source code may have problem.

Running NDN in a IBM NetVista (old P4), the mode change will cause the screen
have garbage and reboot.

They should code a mode detect program and use it's result for NDN.

Please wait for my test, I'm currently no access to that PC.
A bit busy right now.

I'm not sure what mode, because I keep using "next" function, after 2
or 3 clicks it reboot.

Yes, there is active development in NDN...

As for impouving it's display functions I can help, but only if somone 
can make a detailed howto of how to set up it's compile environment. 
Usualy this can take days which I don't have to spare, but I have some 
experience with PC's video. Specially on the compatibility issue.

That's good, it's a fine software.

I need to try it on other PC, but I need some time, and I think mode detection
should be carry out by an external utilities and write the result in a
"vmode.ini" to let the main program use it without crashing anything.

>> Have you contact the developer of Necromancer DOS Navigator?

I want to test on other similar model PC, to make sure this is really a
"problem", rushing to report may not help.

Hi,

The problem with the display is that on *any* (dosemu included) vga 
system there is a standard way to have 25,43 and 50 lines that is fast 
and relyable and BIOS compatible. It works very well in Windows 98 and 
XT dos boxes too.

NDN has many video modes beyond those. I believe that there should be a 
version or an option for compatibility that stick to the basics...

Or code it to assume compatibility unless explicitly told so by user.
