    TITLE  :  Common problems when using BGI graphics in 8514 mode




  Q:   Why won't my video card switch into 8514 mode?

  A:   You must have the TSR called HDILOAD loaded.  This was
       included with your video card.  Also, you must specify
       IBM8514 for the graphics driver when calling initgraph().
       You cannot use DETECT to autodetect an 8514 card.


  Q:   Why am I only getting 16 colors in 8514 mode?

  A:   When you go into 1024x768x256 color mode on your ATI card it
       may look like you only have 16 colors.  This is because the
       palette is set up such that the colors 16-255 duplicate the
       first 16 colors.  If you do a setrgbpalette(color,r,g,b) you
       can indeed set the colors for the whole palette to a
       magnificent rainbow of chromatic brilliance.  Don't forget
       that the values for r,g,b range from 0 to 255 but only the
       upper 6 bits are used (0-63 shifted left 2 bits).  Also,
       you'll need at least a 1 megabyte video card to get 256
       colors at 1024x768.
