ati VGA Edge-16 test 800x600x16 colour mode failure

Post by neozeed »

I was going to try the Windows 3.0 800x600x16 drivers here:
http://www.vogonsdrivers.com/getfile.ph ... ustate=6,1

And they don't work on Windows 3.0 in standard or 386 enhanced mode. I've disabled emm386 so it's just himem.sys.

So I thought I'd try the MS-DOS drivers and the test program here:
http://www.vogonsdrivers.com/getfile.ph ... ustate=6,1

And as you can see it doesn't display 800x600 correctly.

Not a show stopper by any means, thought I'd mention it.

Uh oh! That doesn't sound too good! Did Windows 3.0 in Standard and 386 Enhanced mode work with EMM386 driver disabled or did the problem persist?

I just tried the Windows 3.0 drivers from the WINDOWS 3.0 SUPPLEMENTAL DRIVER LIBRARY

And this is what i get for ATI Mode 54h ... so the same thing.

The ATI Mode 55h for both the Charger and Edge just dump me back to MS-DOS.

To test video cards, I start out with only himem.sys ... Keep it simple see if the driver even works before messing with any of that HMA crap.

It looks like that there is a bug in the ATi VGA Charger and Edge 16 emulated graphics cards.

This appears to be a case of Windows programming some weird register to specify the SVGA display height that PCem doesn't take into account.

It fails in MS-DOS too... so it's something about this ATI mode. I guess somewhere in vid_svga?

No, it would be in the ATI-specific source file. Remember, each adapter is often completely different from the others.

look at the vid_ati18800.c it calls svga quite a bit. and I dont see anything about special modes.
