2.0 Architectural Overview
2.1 Introduction
The Intel
®
Embedded Media and Graphics Driver is composed of a runtime graphics
driver and a Video BIOS (VBIOS) firmware component. (See the illustrations below.)
Both the driver and VBIOS control the SCH to perform display and render operations.
The VBIOS is predominantly leveraged by System BIOS during system boot but is also
used at runtime by the driver to handle full-screen text mode on Microsoft Windows*
operating systems.
