       I found that in an old "help file" of mine :


  Colours   640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200   1400x1050
  --------+--------------------------------------------------------------

  32 bits |    ?       ?       ?        ?      0x164      ?

  Colours   640x400 640x480 800x600 1024x768 1152x864 1280x1024 1600x1200   1400x1050
  --------+--------------------------------------------------------------
   4 bits |    ?       ?      770       ?        ?        ?         ?
   8 bits |   768     769     771      773      353      775       796

  32 bits |    ?       ?       ?        ?       356       ?



  Key: 8 bits = 256 colours, 15 bits = 32,768 colours, 16 bits = 65,536
  colours, 24 bits = 16.8 million colours, 32 bits - same as 24 bits,
  but the extra 8 bits can be used for other things, and fits perfectly
  with a 32 bit PCI/VLB/EISA bus.
