6.3. Text-mode is broken in some ancient DOS program

If you are using a program written for DOS which seems to use the text-mode but doesn't display the text properly, you can try the other VGA BIOS, either VGABIOS-lgpl-latest or VGABIOS-elpin-2.40, see the vgaromimage option.

Maybe it is a bug in the LGPL VGA BIOS, but for now, it seems to work.
