Are you sure it won't work with X386 1.2E? Even after the frequency setting
kludge? Also someone mentioned it might not work with 0.96c patch 1 or 2,
I need to know how sure they are and what is the reason. This is causing
me panic. I am now running X386 1.2 Linux v 1.1 on this card. And I think
from the discussions I read on the net, Diamond Speedstar is better than
ProIIs in terms of performance|speed/price. If win3.1 can treat this
card as a normal Speedstar and give 16 million colors, isn't something
in X386 not following correct programming method?
From what I read, even the speed-up for ET4000 will work on this card,
as long as you have a virtual screen as wide as 1024, is this correct?
Anyway, I agree those who haven't bought their new cards should not
buy this card to save the trouble. But for those who already own
the card, I think the card might have a better future unless the
next version of X386 will definitely not work on it.
