[comp.windows.ms] ET4000 register map needed

rays@bat.lle.rochester.edu (Ray Stewart) (04/12/91)

I am having a problem running windows 3.0 in enhanced mode using my
ET4000 based super VGA card (Ultimate).

Here is what happens:

Everything works fine in Standard and Real modes. I can use the 1024 x 768
with 16 and 256 colors.
When I try to run in enhanced mode I get this sync problem on my Nec 3D.
I think the card switches to non interlaced mode for some reason.
I have tried most everything.
As a last resort I am going to write a program to switch the card back to 
interlaced mode.  This I hope is not too difficult.

If someone could send me a listing the relavent control locations and the
bit definations I would be forever grateful. Also any info on windows video
drivers would be helpful too.

The card is made by LOGUS Technology (no longer exists)

I have tried Miscrosoft and TSENG but the can't help (this should be won't)
