NTVDM.EXE on win 7 32 bit (Emulation)

posted by RayeR Homepage, CZ, 07.06.2020, 17:12

If I remember well it's due to new windows driver model for VGA adapters that doesn't allow fullscreen VGA/VESA (introduced in Win Vista). It should be possible to use some older VGA drivers from XP era for some VGAs in some compatability mode that then could run fullscreen but you may not fully utilize new features/speed of your VGA in Windows so it's not reccomended.
Use some kind of virtualization if the DOS app is not speed critical and need to run still under Windows. E.g. VMWare offers quite good performance in VESA modes.
