I have an Award BIOS 4.51 that I just updated to 2-16-97 version I am running it on a Jet-Board j-656VXB motherboard with a Cyrix 166+ 32 megs memory and a Screamin'3d. N2rend runs like complete ***and ICR2 runs well with INDYSAFE But Locks with INDYFAST as wellas does NASREND -dma. DMATEST gives me an error that it's turned off by either BIIOS or O/S so I have no DMA. I can't find any settings in BIOS that let me specify DMA or PCI latency. Can someone please help me. Is it because I have a Cyrix? I haven't been able to find any real info about this on the net. Any help would be greatly appreciated. Mike Lewis

Either restart Win95 in MS-DOS mode (don't boot straight to DOS) or run DMAdiag before playing. Either of these should enable DMA. Get DMAdiag from my utilities web page. -- The IWCCCARS Project: Q & A Representative [link lost in import] [link lost in import: /~ebusch/] net.

DMA version of the games do not work with Cyrix/IBM 686 CPU. That truely sucks because those 686 CPUs rock in Win95. I went ahead and got myself a Pentium. DMA actually works, and it works rather well. "At the beginning of any project, a high level of e***ment can be found with a low level of execution." - Trevor Harris
: Either restart Win95 in MS-DOS mode (don't boot straight to DOS) or run : DMAdiag before playing. Either of these should enable DMA. Get : DMAdiag from my utilities web page. With some of the changes Award has been making to their 4.51 BIOS, one might need to run DMAdiag even if restarting Win95 in MS-DOS mode. Get the utility, but do not try running it in a DOS "box" in Win95. Only use it in a pure DOS environment. Just run it as part of the boot-up process and the DMA should be enabled until you reboot. -- **************************** Michael E.

Actually with Eric Busch's help, I've got Nascar2 running with DMA but I'm still having problems with ICR2 (Indyfast) I do get 45-50 FPS while running Indysafe. I do get very low scores with DMADIAG 28.006blah blah DMA Mike Lewis

I guess this is an appropriate "add on" here ;) I'm running a Cyrix 586 120.... I just did get the Intense3D board, and the RENDDMA.BAT file works.... but hick-ups. the graphics are clear and smooth (very nice!) but the input from my T2 seams to be picking up an interruption... I HAVE to calibrate every time I start up. It is playable, but frustrating to have invested in this card, specifically for this game, and it doesn't run perfectly. If I even suggest getting an Intel MB/CPU, my wife WILL cut my life short (LOL). With the card I got ICR2, which runs flawlessly.... using INDYSAFE.BAT... INDYFAST doesn't work. However, the indysafe mode is nice. Keeping an ear to the track...

The Cyrix, DMA, and joystick problem is known, and there is no solution for it. (For a longer technical discussion of exactly why, look on www.dejanews.com for my prior post in this group.) ---Jim Sokoloff, Papyrus
