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
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.
