Other x86-Based Miniports

Miniport drivers that are set up to configure themselves in the registry with VgaCompatible set to zero (FALSE) have the following features:

• Such a miniport driver provides no special support for full-screen MS-DOS applications in x86-based machines. Instead, it is loaded along with a system-supplied VGA (or, possibly, with a VGA-compatible SVGA) miniport driver, which provides this support for full-screen MS-DOS applications.

• In most cases, such a miniport driver either is written for an adapter that has no VGA compatibility mode or for an accelerator that works independently of the VGA.

If a new miniport driver cannot provide support for an existing display driver a corresponding display driver must be written together with the new miniport driver.
