Ian, We chose the XGA IIT – AG????? Vibrant drivers for 3DSr3 and they work fine. Ang

All's well now, I was missing thye VESA driver.

If you use "3DS VIBCFG" to set up 3DSr3, you should see "Hercules Graphite" as one of the options. You don't need the RCPADI driver that came with the card. The Graphite is an XGA clone, and will thus work with any XGA driver for any program that supports XGA, though you get more performance and higher supported resolutions and color depths with a Graphite or at least IIT AGX specific driver such as the ones provided by VIBCFG. Because it is an XGA clone, you ***MUST*** eXclude "B100-B1FF" from your memory manager!

I am eXcluding the A000-C7FF that Hercules recommends which would cover the B100-B1FF range. But something is wrong; 3DS crashes periodically – always after changing screens. Sometimes after rendering, sometimes when switching to the material editor. Its particularly annoying because my BIOS has no memory check bypass, so I have to sit there tapping my fingers while it counts though 64mb after every crash.

You might need to get a new version of the VESA TSR for the card. Early TSRs from IIT had some major problems, but Hercules fixed most of them.

Thanks, will check it out. Ian.

FWIW some Micronics MBs have an undocumented memory check cancel by pressing the space bar…. David Taffet

You may have just changed my life. Michronics tech support didn't even mention that.

Happy to be of some use, here. <g>

Actually, the AGX isn't exactly an XGA clone. It works like the XGA, but initialization is an entirely different ballgame. The AGX (The chip the Graphite is based on) is actually a VXE device. XGA drivers will not work on the AGX, but VXE drivers will. VXE is a standard from VESA that defines a method of querying an XGA device to find out where it is mapped and what modes it supports, and how to access those modes.
