Thanks for your suggestion.

I posted dos101b.zip with changes to support this.

OLD: diabaig.exe switches to 80x43 mode unconditionally
NEW: diabaig.exe switches to 80x43 mode if current text mode is below 79x34

vga34.bat uses 480 scan lines for 80x34
vga36.bat uses 11-line font for 80x36

On my IBM PC 330 with S3 Vision864 SVGA, vga36.bat works fine but vga34.bat results in 80x28, so diabaig.exe switches to 80x43. :(

In qemu, vga34.bat works fine too.
