CADvance The driver is loaded into memory by CADvance and therefore doesn't require any additional steps by the user. CADvance also removes the driver from memory at the end of a session. CADvance is started in the highest possible resolution by default. If you wish to change this then you must set an environment variable in the following way: SET S31_911=mode number mode number is: 0 640 x 480, 256 colors 1 800 x 600, 16 colors 2 800 x 600, 256 colors 3 1024 x 768, 16 colors 4 1024 x 768, 256 colors 5 reserved 6 reserved 7 1280 x 1024, 16 colors 8 reserved Note: Please note that not every video mode may be available. If you have enough system memory, you can use this driver as a rendering unit. The resolution is the same as for the 2D and 3D modes. Please note however, that rendering will only work if the driver is currently using a 256 color mode.
