mattmon Posted March 31, 2007 Share Posted March 31, 2007 I'm trying to do this as well, I have a Dell 30" with a Dell 20" (rotated vertically) on either side. I have 4 video cards at my disposal: Diamond BV300 (X1300, Dual-DVI), PNY Verto 7900GS, Dell QuadroNVS, Genuine Apple 7600GT. The PNY card drives 2 displays flawlessly using Natit_Dual v2 The Apple card works as well, but curiously still needs Natit to load drivers... The X1300 is only working with a single display. Have not seriously tested the Quadro, I know it works fine with Natit and 1 display. With 2 cards installed, the best I've been able to acheive was successful recognition of the X1300 while also using the PNY/Apple cards, but with no display output from the X1300. Nvidia cards were using Titan, and ATI using Natit with various card-specific plist settings - Natit alone does not seem to support 2 cards simultaneously. The system I'm using, which actually supports OSX86 pretty well "out-of-the-box" is a Dell Precision Workstation 490 - very similar to a Mac Pro;) Link to comment Share on other sites More sharing options...
asimovrobot Posted April 2, 2007 Share Posted April 2, 2007 I had a similar question on here a couple of weeks ago. Only difference is that I don't care if my 2nd video card works or not... I just want it to be able to be in the system so that when I boot other OS's it will be there and working. All I would like to be able to do is make OSX ignore my 2nd video card as when it is in the system it causes a kernel panic everytime. I run a 7600GT and the 2nd card is a 7100GS. When the 7600GT is running solo everything is fine but as soon as 7100GS gets in there I get a panic and cant remedy it without removing 7100GS. Has anyone tried 2 identical cards(non-SLI)? I tried adding the devid for 7100GS to the appropriate places but it had no effect. Just a side note... originally I had trouble getting QE/CI working with 7600GT and before I figured out that I was missing some of the geforce*.bundle files the system did ignore the 7100GS. Once I had the geforce*.bundle files and QE/CI supported then it starts getting the panic with the 7100GS. Link to comment Share on other sites More sharing options...
rhalls Posted April 2, 2007 Share Posted April 2, 2007 I just tried that with an XFX 7600GS and the integrated GMA 950 - i had the hope to use three monitors (2 on 7600, one on 950) - didnt work. Maybe with two identical cards ? Dont know Link to comment Share on other sites More sharing options...
mattmon Posted April 4, 2007 Share Posted April 4, 2007 The method Ive tested with the most promise so far has been the PNY 7900GS with an X1300 based diamond BV300: I modified Titan to recognize only the 7900, and Natit Dual v02 to not detect the 7900 (thus ensuring only the X1300 was found). At first, the ATI card would show only as a display while the 7900 worked flawlessly - after a good amount of plist twaking, mostly copying stuff that seemed relevant from Diabolik's X1600 kext, I had the Natit properly detecting my card - however the system log still produced display realted errors (which I regretfully didn't copy & save). After that, I relaized that Titan and Natit were doing essentially the same thing, and questioned my own reasoning in attempting to utilize both simultaneously. This all led up to my latest hypothesis, which is to test both a combination of Titan/Natit as well as Natit alone while tweaking the [entriesToAdd->default->"@N,xxx"] keys from being exclusively @0,xxx / @1,xxx (twice in my case) to @0,xxx - @3,xxx representing a unique key for each display port installed in the system? Can anyone else offer any further insight into this subject? Link to comment Share on other sites More sharing options...
