The driver for my SVGA doesn't seem to work.

Most current SVGA adapters are VESA-compatible, so try the VESA driver built into go32 first. Do not define any driver in the GO32 environment variable (so that go32 will use its internal driver) and try to run some graphics program. (You might want to run it first with the vga.grd standard VGA driver, so you will know how the correct display should look like.)

For some cards the updated versions of their drivers are in grx103m1.zip maintenance release of GRX, so if the above doesn't work, download that file and look for a driver suitable for your card.

If the driver you need cannot be found neither in cbgrdXXX.zip nor in its maintenance releases, or don't work right, try anonymous ftp to omnigate.clarkson.edu, directory /pub/msdos/djgpp/pub. There are some contributed drivers there.

There is also a program called display which includes some additional graphics drivers. display is available as dispNNN.zip on SimTel mirrors in the SimTel/msdos/graphics/ directory.
