linear Posted January 21, 2006 Share Posted January 21, 2006 I recently got 8f11111A installed and working. I had a few minor problems with windows samba access, shutdown, and quicktime. I fixed the samba problem (search this forum for my username if you have a similiar problem), can deal with the shutdown, and can use quicktime by disabling Quartz Extreme (using Quartz Debug.app) but have been completely stuck getting mutiple monitors to work. I have the ever popular ASRock-915DualGL and a PCI Number Nine Revolution IV for my SGI 1600SW lcd. When I boot up osx86 with the "Onboard VGA" set to Auto the built in VGA becomes disabled and I can actually use my SGI1600SW in osx albeit at 1024x768. (this is also the only display in the System Profiler) This is a vast improvement as I could not get my G4 tower to even recongize this card. When I set the bios "Onboard VGA" to enabled then I get the ultra accerlated GMA9000 working wonderfully. I checked the System Profiler and it does in fact recongize both graphics cards, but the Number Nine Revolution IV is listed as Display: Type: VGA-Compatible Controller Bus: PCI Slot: PCI Vendor ID: 0x105d Device ID: 0x5348 Revision ID: 0x0002 Kernel Extension Info: No Kext Loaded Displays: Display: Now I hardly expect native drivers for the card, but I would still like to have a multi monitor set up even at 1024x768 without hardware acceleration. Any ideas?? Note of interest: Both monitors work wonderfully together in windows as long as "Onboard VGA" is enabled. Oh one last thing. When I open the Display Preference Pane, When both cards are enabled, I see a button that says "Detect Displays", although when I click it, nothing appears to happen. This button is not there when I boot with only the 1600SW enabled. Since I've never run osx with mutiple monitors I do not know what to expect in this preference pane, but my guess is osx is trying to enable the second monitor but is unable to... Please Help!

urig-herb Posted January 21, 2006 Share Posted January 21, 2006 Ok, I can't help you but I recommend that you sell your 1600sw as soon as you can and get for the same many (they still pay a lot for them on ebay, especially for the number nine card) a latest generation display. The 1600sw was really good. I used one for four years. But compare it with the latest TFTs. They are so much better now.

Ok I give, I love this monitor and i've gone through both the 3dlabs pci card and the number nine video card with the 1600sw, and thought about the multilink adapter, I'll consider selling it. Then what may i ask will allow me dual monitor support in osx86 with the onboard igma900 and the asrock915-gl? Also does anyone have an add2 pci-e card that it giving off DVI-D? I got a Silicon-image orion add2-n Dual Pad x16 and my motherboard hasn't recongized it...

bofors Posted January 24, 2006 Share Posted January 24, 2006 (edited) I am actively working on the dual display issue right now. If you search the forums, you will find several people who have successfully used ADD2 cards with GMA motherboards. You should also now that Apple itself used ADD2 card in the original Developer Transition Kit (there was no VGA port on the motherboard, just DVI-D via that ADD2), so the support for it is good and I suspect something about your ASRock Dual motherboard maybe the problem. I expect to be ordering an ADD2 card in the next few days (if not immediately) and will report my results here (as well as in my signature thread). (By the way, this thread should be in the hardware forum). EDIT: I just found this thread which confirms dual display support with an ADD2-N card: http://forum.osx86project.org/index.php?showtopic=569&hl= Edited January 24, 2006 by bofors Link to comment https://www.insanelymac.com/forum/topic/7350-mutiple-monitors/#findComment-47434 Share on other sites More sharing options...
linear Posted January 30, 2006 Author Share Posted January 30, 2006 I understand that my ASRock or my ADD2 card might be the problem. I haven't been able to tell which one it is as I do not have another system to test the ADD2 card on. I am more interested in enabling my second monitor. That is why I did not post this in the hardware forum. I have seen both monitors work with both video cards (not with the ADD2, but the onboard intel gma and also with the sgi1600sw number nine), but not at the same time. And your link states that people are using dual displays with mutiple graphic adapters. So my question that I'm asking is Where do I start looking around to force the second monitor on? I know how to do this in Windows (and I mentioned that both monitors work fine in Windows). Or am I just asking about the impossible, and that dual monitors just won't workin with the number nine revolution 4 for some reason, but nvidia cards do?

bofors Posted January 30, 2006 Share Posted January 30, 2006 I am not sure about this "[how] to force the second monitor on" question. Note of interest: Both monitors work wonderfully together in windows as long as "Onboard VGA" is enabled. Does this means that you have tested your exact same hardware configuration in Windows and it works? I mean, you have postively isolated the problem to OS X? It sounds like you haven't: "my ASRock or my ADD2 card might be the problem". Let's try to isolate hardware from software here, I think you should test it on Windows next. By the way, I working on a similiar problem now with another forum member here: http://forum.osx86project.org/index.php?sh...ic=7393&st=100# Link to comment https://www.insanelymac.com/forum/topic/7350-mutiple-monitors/#findComment-50313 Share on other sites More sharing options...
bofors Posted January 30, 2006 Share Posted January 30, 2006 I just got my ADD2-N card. No problems here, it worked right out of the box. I made no adjustments. The only thing I noticed is that the computer booted in a mirrored mode, BIOS splash screen and OS X start-up screens on both displays. Then OS X switched to extended desktop mode: GMA 950: Chipset Model: GMA 950 Type: VGA-Compatible Controller Bus: Built-In VRAM (Total): 256 MB Vendor: Intel (0x8086) Device ID: 0x2772 Revision ID: 0x0002 Displays: DELL 2005FPW: Resolution: 1680 x 1050 @ 60 Hz Depth: 32-bit Color Core Image: Supported Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported SyncMaster: Resolution: 1280 x 1024 @ 75 Hz Depth: 32-bit Color Core Image: Supported Mirror: Off Online: Yes Quartz Extreme: Supported Link to comment https://www.insanelymac.com/forum/topic/7350-mutiple-monitors/#findComment-50466 Share on other sites More sharing options...
linear Posted February 6, 2006 Author Share Posted February 6, 2006 Does this means that you have tested your exact same hardware configuration in Windows and it works? YES! It works great in windows, without the ADD2 card. As far as I'm concerned my motherboard is defective. Not only have a caused some sort of short when it was on, causing my power supply to go poof!, but upon further analysis the traces on the back, especially around the pci-express look to be a problem. So I'm content with my analog for the moment. I will look into buying an official intel board next time. As for the 1600sw, what I mean is that the onboard GMA and the PCI number nine IV work together in windows xp no problem. In OSX I can get the 1600SW to work in 1024x768 when I disable the onboard GMA, but cannot get both to work at the same time. What I meant by force it... I meant that both monitors work independently in OSX, why can't I use them at the same time. There must be some way to force the OS to recognize both..... Any ideas??? Also if I were to buy a graphics adapter to replace my number nine IV, what seems to be the best supported under osx86???
