I think this is not true. OS/2 will *only* run in 1024x768x256, i.e.
1MB mode of the 8514/A (I have one from WD). The docs say clearly that
it does not run with only 512k. It is true that OS/2 1.x does not really
supports 256 color software with a palette manager as Windows 3.0 does.
But it displays 256 colors on the screen when I use DESKPIC to display a
256 color GIF file on the desktop, although the colors get matched a bit
to the available system-defined 256 colors.
