I recently purchased an ET4000 VGA card with 1MByte memory and the
Tseng chip set.  When I ran the diagnostic program which came with 
the card, it produced several 'read' error messages when I ran the
card at a 12MHz AT bus speed.  The errors continued at bus speeds of 
10MHz and 8MHz.  At 6MHz , the card seemed to pass all the diagnostics.
I called the store where I purchased the card and was told it was 
probably the diagnostic program at fault and that they would send me
another copy.  QUESTIONS TO THE NET:  1) does anyone have any experience
running an ET4000 card at high bus speeds, and 2) do any other 1MByte VGA
cards run at bus speeds of 12MHz or higher?

Thanks for your support,
