Figure 7-8: Graphics Device Frame Buffer SubDevice Properties

Difference from Real Hardware

The Emerald Graphics device currently does not simulate any specific graphics hardware, it simulates something functionally “like” a modern graphics adapter, with only 2D acceleration implemented at this time. Drivers are Windows only at the moment.

When the VGA display window has the focus, any keyboard messages and mouse-click messages received by the window are routed via a DEVCWINDOWMSG message through the simulators I/O subsystem. The keyboard or mouse device accepts these messages and simulates key-presses and key-releases to match the keys. While certain key combinations do not result in the generation of keyboard messages by the OS, this does enable you to use the real keyboard to interact with the simulation in many cases.

Supported VESA BIOS Graphics Modes

Only supports flat and linear frame buffer, with 16-bit/64K (5:6:5) colors and 32- bit/16.8M (8:8:8:8) colors modes.
