Your video card may support these modes but needs a special driver to
access them in DOS. For example, I have a Viper video board which by
the book says that I support these modes and more however when I run
a program that calls these mode it gets a -1. If I load a VESA driver
before running the program it works. You may need an external VESA
driver for your card to access these modes.
