Chapter 7: Device Configuration 65
7.5 Matrox MGA-G400 PCI/AGP
The Matrox G400 graphics device provides a high performance PCI/AGP VGA-
compatible video device. The device provides a fully functional set of PCI configuration
registers, and a 2D drawing engine. The AGP interface is currently somewhat minimal,
and is not capable of generating neither AGP cycles nor AGP-specific modes at this time.
High performance device drivers are available for most operating systems (Windows,
Linux, and Solaris). The Matrox G400 supports full acceleration of all GDI and
DirectDraw functions.
Figure 7-9 shows the integrated components of the Matrox G400 graphics device.
Features and components which are currently not supported by the Matrox G400 graphics
device model have a symbol in the following block diagram.
