I have discovered my problem. The the last 8 (?) or so palette slots
aren't initialized and I was testing the drivers with BGIDEMO. BGIDEMO
uses setcolor(MAXCOLORS-1) to plot most things. This won't show up if
color 255 is 0,0,0 (black). When I changed the setcolor() and also
explicity set to colors less than 248 the drivers work fine.
Thanks to all who responded.
