Intergraph Reactor (DMA) question

I just (Yesterday!) got a Reactor card and now would like to run Nascar 2 with the rendition mode. Renddma does nothing except crash very quickly. (screen full of "pixel dust" not much more) nasrend (alone) works fine, but (I must be blind?) I cant see much of a difference besides a slower frame rate. (Old card was a Diamond Stealth 64 Video 2001 series). I also seemed to notice that I can't use the univbe (ok, UVCONFIG.EXE) as my video card isn't supported. (?) -Any insight would be greatly appreciated!

Have you tried running DMAtst or DMAdiag (get them from my webpage)? BTW, you don't need the univbe, as the Reactor has on-board VESA 2.0. -- Emory University Graduate School of Arts & Sciences The IWCCCARS Project: Q & A Representative Nascar Setups Page: http://userwww.service.emory.edu/~ebusch/

Download a copy of DMADIAG from the Late Night website (URL in my sig). For most people who have this problem, running DMADIAG prior to running NASCAR 2 fixes the problem. Also, you should download the latest Reactor BIOS from the Intergraph site. If you can't find it there, I think Eric Busch has a copy on his website.

I had the same problems (couldn't tell the difference between n2 & n2rend / renddma=pixel dust) when I ran it in dos. Windows allowed me to run it in renddma. I haven't tried to hook my steering wheel up to it though, so I don't know if it will be jerky. Also I haven't tried to get sound to work yet. but I was able to run Talladega with EVERYTHING on 39cars 15 ahead, 3 behind. Cyrix 686 P166, 32megs, Reactor.

for some bizarre reason, DMADIAG: (a) Crashes (locks up tight) when I boot in DOS mode (F8, option 6) (b) simply ends when I double-click in Win95 or by restarting in MS-DOS mode (Start menu, end, restart in MS DOS) and MS-DOS prompt. Suggestions still welcome, sorry about the delay

I had the same problem when I accidentally mixed up files between Dmadiag and another application (I think Dmatest). I unzipped them again using separate locations and the problem went away. My poor DMA performance didn't go away though<G>. Good Luck, Mike Radler

Sounds like maybe your system has a problem with 1st party DMA. Try hunting around in your BIOS settings to see if there's a switch to enable DMA on the PCI bus. Also, you might want to see if there is a BIOS upgrade for your motherboard. Dave (davids) Sparks Late Night League http://www.sequoia-dev.com/Hawaii/latenite.html
