And I should be able to get millions of colours at 1280 x 1024, but it
only allows thousands. :-(
It is recognising as least 3MB of VRAM (1024x768x24-bit colour = 2.25MB).
I will have to check both simms and make sure they are seated properly.
Do you have as much trouble as I do getting the cover off? It is easy
to get at everything once the cover has been removed, but hard to get it
off in the first place.
