Need some help: I have a shiny new Gateway 200 386sx machine with DOS 4.01 &
Windows.  The video is a Diamond SpeedStar SVGA with 512K.  Floppy disks
with video drivers are included.  Last night I loaded the new SETUP.INF and
Windows drivers and selected "Diamond SpeedStar 800x600 256 colors" in setup.
The process seemed to go smoothly, I was directed to load a couple of the 
Windows floppies from which it obtained font information and perhaps other 
stuff as well.

Unfortunately, when I restarted Windows, the display wrapped around from
bottom-to-top, i.e., the bottom part of the display wrapped around to the
top.  It's almost as though the display was not 600 lines high except that
there is overlap between the bottom part of the display and the top so that
anything which appears near the bottom of the screen may appear, in part, on
both the bottom and the top of the screen.  This includes windows, icons,
wallpaper images and the mouse pointer.  Very strange.  I changed the
display back to "VGA" and all was well again.  When I tried "Diamond Speed-
Star 800x600 16 colors," that also worked fine.  Tried 800x600x256 again,
wrap-around returns.  I should have tried 1024x768x16 (don't have 1MB for 
256 colors... yet, but I did get a non-interlaced monitor - special deal 
$50.00 extra), but Griffin, my computer, told me it was late and that I 
should go to bed and work on this later.

I'm no newcomer to computers, including PC's, but I am new to Windows and
I may have committed some bonehead error.  I have read TFM, so though I
may have misunderstood or even overlooked, it isn't because I didn't try.
I do run FractInt 15.1 at 800x600x256 which works just fine - love those 
colors - though I note that the 800x600x256 selection I've been using 
refers to VESA (I know what the acronym is, but little else about it) and 
it may be different from the Windows driver.

Can anyone help.  I will take email or postings and I will gladly summarize
if others are interested.

Larry
