  I just installed DJGPP 1.11, and have these problems with its graphics:

   - I must use ``nodpmi'' in the GO32 environment variable, otherwise
     I get General Protection Fault when doing graphics.  This happens both
     in the t05 test program in the tests directory and the grtask program
     in the samples/grtask directory.  I use Quarterdeck's QEMM 7.03 and
     QDPMI which came with it (1.02 if I'm correct).

   - The built-in VGA driver behaves differently (and, as far as I could
     understand from the program sources, incorrectly) than the vga.grd driver
     in the drivers subdirectory.

   - I have a VESA Local-Bus SVGA with OAK OTI-087 chipset, but when I tried
     to use the supplied OAK.GRD driver, I got the graphics on the upper 1/4
     of the screen only :-(

  Also, I couldn't find documentation of what is displayed by GO32 on the
top line of the display.  Some of the info I guessed, but some of it is still
a mystery (especially those quick-flickering items at the right corner...).

	Thanks,
