This sounds a bit hectic for me, the card is probably way too old now, I've noticed that SIGMA Designs don't even seem to want to support it. Their website has a driver pack "for all their cards", except it doesn't work with this one, for DOS I need the original driver disks... and Windows (which incidentally deleted itself lastnight! =( ) just isn't having it (no surprises there!). > Some old voxware driver might have some support for this card but you > need the DOS code from the dos driver. Now this sounds worth trying, my problem here is that although the card does sound and video, I'm more concerned about video really if there's going to be any trouble involved.. This is only really because I doubt anyone else still has one of these boards and isn't a DOS/Win3.1 user! > > Other than that, I'd be interested in getting the mpeg side of the card > > working..

That, would be nice, but of course someone would need the original code or chipset specs (I guess if someone already has them ??...). Personally there's no way I could do this, mostly because I know less about writing drivers than I know about the El ninio (?) phenomenon. But lack of time could figure as a poor excuse as well. If there's a chance I could get it to work I'm willing to try though. Steve. Steve Roome - Vision Interactive Ltd. Tel:+44(0)117 9730597 Home:+44(0)976 241342 WWW: http://dylan.visint.co.uk/
