Anybody got any advice on producing graphics on OS2 without going through PM? (I
know, I know, stupid but got to do it!)

Basically I have to put up a company logo on an OS2 full-screen when the product
starts up. This being practically a straight DOS conversion, the product is
being given a total DOS feel and thus no PM is wanted.

Micheal Youngs book on OS2 suggest using VioGetPhysicalBuffer to get a hold on
the video ram and then writing directly to it with threads handling switching
and redrawing. It looks very intricate, nasty etc, so I would like to know what
problems are going to be involved in doing this and any experiences anyone has
had in similar circumstances. Any easier way of doing this or a better book on
the subject that Micheal Young's?

	Thanks for any help.
