I think that the 16 grey shades were for CGA/EGA only (mode 0 and 2).
For MCGA/VGA all 4 modes are 16 colours.

But I was just trying to show b152 that the original definitions for CGA and EGA adapters were indeed different. All he is seeing is the "modern" VGA emulation of those Wink
Why he's even bothering with them I don't know...
