First, check out the internal GO32 driver which should work
with any VESA-compatible driver (most of the latest cards
are).  This driver is used whenever no driver is mentioned
in the GO32 environment variable.  Run the GrTask program
which comes with djdev112.zip file; there is also graphics
test program in djtst112.zip.  It is best to first run these
with the standard VGA driver (set GO32=driver c:\djgpp\drivers\vga.grd)
so you would know what is the ``correct'' display.  If the
internal driver doesn't work, add ``nc 256'' to GO32, like this:

	set GO32=nc 256

This fixes most VESA-compatible cards.  If it doesn't for
your cards, then you could try the 8514a driver which comes with
the DISPLAY program (you can find it on SimTel mirrors as
DISP187A.ZIP and DISP187B.ZIP.  For the Commodore PC-60, find
out which chipset is used for its graphics card and use the
driver for that chipset.
