Interfaces

The Matrox G400 graphics device has both a PCI bus and an AGP bus connection, only one of which can be used at any time to connect to PCI bus or AGP bus ports in other devices.

Initialization and Reset State

Upon initial creation, this device initializes the internal registers to Matrox G400 standard reset state, and creates a display window that acts as the VGA display. The Configuration options are initialized to enable both the VGA and Matrox Power Graphics Mode. The frame-buffer size is initialized to 32 Mbytes and the Bios File memory area is initialized to all ones.

A reset will re-load the default PCI configuration registers and place default values in the Chip and FIFO configuration for the Matrox G400 graphics device.

Contents of a BSD

The data saved in the BSD depends on the mode the graphics controller was in when the BSD was saved. If the graphics controller was in VGA mode, the BSD file contains the contents of all VGA registers, a copy of the 256-Kbyte VGA frame buffer, and all configuration information. If the graphics controller was in Matrox Power Graphics Mode (non-VGA in Windows) the linear frame buffer, Power Graphics registers, and PCI configuration registers are saved in the BSD. When the BSD file is reloaded, all registers and the frame buffer are restored, and a display image is captured and displayed in the display window.

Configuration Options

Figure 7-10shows the Information tab. The following information describes the active configuration of the Matrox G400 graphics device.

The Graphics Hardware Model can be set to one of the following models:

Matrox Millennium G400 PCI

Matrox Millennium G400 AGP

Currently there is only support for the Matrox G400 chip with SingleHead feature support available.

The Graphics BIOS version is the version of the BIOS that is assigned and used by the graphics device. If you flash the BIOS the version number will change. For more information about flashing the graphics device BIOS see Figure 7-11.

The Graphics Memory section shows information about the current memory configuration of the graphics device. Currently supported memory configurations are:

32/16 MB SGRAM with 300 MHz RAMDAC

32/16 MB SDRAM with 300 MHz RAMDAC
