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.
