Thank you folks for this site.

uuuuuuuuuuuuuoooooohhhhhhhh man!!!...... i'll try this when i'll finish downloading the newest ideneb 10.5.7 dvd... then i'll report

immediately back to you... i only hope that the system will see both gpus of my asus gtx 295... :unsure:

Yes.

The EVGA GTX 295 Co-op Edition works under Snow Leopard. It's awesome. Both 32-bit/64-bit works. Also sleeps works. This is on a Gigabyte GA-EP45-UD3P motherboard. I created an EFI string and inserted that into the boot plist file. In addition to this, I had to insert 0x05eb10de&0xfff8ffff into the NVDANV50Hal.kext/Contents/Info.plist file.

Run as root afterwards:

kextcache -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

Use gfxutil to convert to hex and add to the boot plist file. Run gfxutil -f display and change the PciRoot key.

Good luck. I did this today to try to make this work so that I could run SL in 64-bit mode. The Netkas ATY_Init kext is currently only 32-bit. (this works for 32-bit if the EFI string doesn't work for you).

I'm attaching a picture which shows both GPUs being seen by OpenCL.

Ok here my setup

Asus Rampage Extreme socket 775

Asus ENGTX295 (dual gpu) 1792MB , Both gpu's have the same id: 10de:05e0 (I dont have to insert the "0x05eb10de&0xfff8ffff" for this card)

intel4x:~ ginobadouri$ gfxutil -f Display

DevicePath = PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x2,0x0)/Pci(0x0,0x0)

I'm currently running OSX 10.5.8 with the EVGA GT200 drivers and ATY_Init.kext.

The first PCIRoot key is what gfxutil -f Display shows.. The second is almost the same only I changed the last part from 0x2 to 0x0.

I don't know if this is right.. cant gfxutil give me both PCI keys?

I'm not using any smbios.plist or dsdt.aml files.

I've cloned the Snow Leopard final disc into a seperate partition and only added fakesmc.kext (for SL) into /S/L/E

Then recreated the kextcache.

When SL boots I can see fakesmc and NVDANV50Hal being loaded but when the screen inits it only gives a black screen and hangs.

The same happens for 10.5.8 when I try to boot it without ATY_Init.kext.

So there must be something wrong with my gfx.plist?

meroy · September 9, 2009

Ok here my setup

Asus Rampage Extreme socket 775

Asus ENGTX295 (dual gpu) 1792MB , Both gpu's have the same id: 10de:05e0 (I dont have to insert the "0x05eb10de&0xfff8ffff" for this card)

intel4x:~ ginobadouri$ gfxutil -f Display

DevicePath = PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x2,0x0)/Pci(0x0,0x0)

I'm currently running OSX 10.5.8 with the EVGA GT200 drivers and ATY_Init.kext.

My bootloader is Chameleon 2 rc3

gfxutil -f display reported this for your first PciRoot entry. Okay, this one is correct.

PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)/Pci(0x2,0x0)/Pci(0x0,0x0)

Acquire IORegistryExplorer. Remove the GFX EFI string from your boot plist file. Put back the ATY_Init Netkas extension. Refresh the Extension.mkext file: (assuming you installed ATY_Init under /S/L/E)

sudo kextcache -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions.

Boot using -x32. Run IORegistryExplorer. Select IODeviceTree from the first pull-down menu. Type display in the search field. Click on each display@0 or GFX@0 entries. Look for NVCAP and write those values somewhere. Also pay close attention to the IODeviceTree value for both displays (just below the search field). This will help determine the correct setting for the 2nd PciRoot entry in your gfx.plist file. The NVCAP value is what ATY_Init injected. You want to use and convert this for your gfx.plist NVCAP entry.

This is what I did to get my single pcb edition working. Both PciRoot and NVCAP entries must be correct. See if both NVCAP entries are the same for both GPUs. If not, you will need to adjust accordingly inside your gfx.plist file.

Good luck.

MastaG · September 9, 2009

Thanks bro it worked:)

You're the man!

I've found another gfx.plist from a french site which was closer to my system.

I used PlistEdit Pro to edit in the NVCAP and NVPM values which I got from IORegistryExplorer and ATY_Init.kext

IORegistryExplorer is a great app since it shows the correct PciRoot keys for both adapters.

IORegistryExplorer shows NVCAP for both adapters but the NVPM value only shows up on the second adapter, so I removed it from the first one in my gfx.plist

All works great now and both dvi ports work.

It only reports the VideoRAM wrong. The first cards shows up with both connected displays and 896MB and the second adapter only shows 512MB without any connected displays but that's ok.

Thanks for everything!

You're almost there. You can fix your ram setting. Change the value for the first VRAM,totalsize setting from AAAAIA== to AAAAOA==. Both need to be set to AAAAOA== for your GTX 295 card (each GPU having 896 MB of ram).

Congratulations.

Congratulations.

I am in exactly this same position *scratching head* I have made the changes and added AAAAOA== for both VRAM,totalsize yet SnowLeopard is reporting the second GPU as 512Mb still.

Strange. I wonder if OpenCL sees them .. Im gonna go check

Did you remember to remove ATY_Init.kext from /S/L/E and refresh your Extensions.mkext. The presence of ATY_Init.kext will override GFX entries configured in the boot plist EFI string.

If you want to keep ATY_Init.kext in place, change VRAM,totalsize inside ATY_Init.kext/Contents/Info.plist to AAAAOA== and refresh your Extensions.mkext.

sudo kextcache -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

meroy · September 10, 2009

Run this command to refresh the system kext cache files under Snow Leopard:

sudo kextcache -system-caches

This will refresh the following files:

/System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext

/System/Library/Caches/com.apple.kext.caches/Directories/System/Library/Extensions/*

IOKitPersonalities_i386.ioplist.gz

IOKitPersonalities_x86_64.ioplist.gz

Ok, headed home from work now. Going to try this right away! I was under the impression that I needed ATY_init.kext to be able to operate at all but I've been reading a bit and I guess all it really does is allows the dual monitor stuff to work. I think I have that right ... right?

Both displays works on my system without the Netkas ATY_Init kext. The EFI string in my boot plist is all I have configured for my graphics card.

In any event, that explains why you're still seeing 512 MB. The ATY_Init defaults to 512 MB. Folks are able to change the VRAM,totalsize in ATY_Init plist to match their setup. Refresh Extensions.mkext afterwards. You should see 896 MB for both GPUs on your GTX 295 card.

Thank you for the kext. I no longer need to add the 05eb entry to the NVDANV50Hal.kext plist file. Your kext works from /Extra/Extensions.mkext too.

Awesome.

I'm having a few issues getting my Gigabyte GTX 295 (single PCB) recognised properly under SL. I have PC EFI 10.3, which apparently has a "graphics injector" option that I'm using, as the Enabler package does not seem to want to install. Likewise with the EVGA drivers, they refused to install, but I manually installed the three packages inside the single master package. I've also added my dev-id (05eb10de) to the Info.plist in NVDANV50.kext.

System Profiler recognises two video cards, one named "Display" and one named "Unknown". The unknown one correctly reports 896MB of VRAM, the display reports nothing at all. The OpenGL extension viewer only offers the Apple software renderer, making me think that drivers aren't loading correctly. Here is my kernel boot up log (I've snipped the timestamps and "localhost kernel[0]:" for brevity) that backs up this thought:

*snip*

Any ideas?

EDIT: Solved my dilemma, explained below.

can any one explain step by step how to install an EVGA GTX 295 Coop in snow leopard?

im quite new to all this and i cant quite get my head around meroys instructions!

im not sure where id get hold of the NVDANV50Hal.kext ....

im running a retail snow install on a GA-EX58-UD5 using Digital dreamers script,

it currently shows up in system profiler as having only 32MB of VRAM, and i know that isnt right!

snow leopard with a GTX295 would be wicked

It is indeed wicked.

I too used d_d's script, albeit with a Gigabyte GTX 295 (rev 2.0) and a GA-EX58-UD4P. The first time around, I made the (apparently quite silly) mistake of force-installing the EVGA drivers for OS X 10.5 and trying (but failing) to install netkas' graphics enabler.

It turns out that netkas' enabler is already built into his PC-EFI tool. What I did was choose Chameleon 2.0 RC3 bootloader from d_d's script (this requires a DSDT file in your /Extra directory) and replaced the /boot file with PC EFI v 10.3. I then turned on the option in the /Extra/com.apple.boot.plist for GraphicsEnabler = yes. This caused boot-up to hang as it recognised a video card, but could not find drivers for it.

To solve this, I edited the Info.plist in NVDANV50.kext (in /System/Library/Extensions) and added my device id 0x05eb10d0. The system now booted successfully, but showed "Display" and "Unknown" as the graphics adaptors. I finally turned off the graphics enabler and instead opted for the EFI string as meroy explained, which gave me great joy as it provided the correct information in System Profiler.

Just a short while ago I updated to 10.6.1 and my computer would hang at boot up. I confirmed my suspicion (using my Macbook) that the update had modified the NVDANV50.kext file. I then switched to the alternative of using Rph4's NVGTX295.Fix.kext in my /Extra folder. This allows for a nice vanilla Snow Leopard with complete GTX 295 support.

(Sorry if this was long-winded, but you might find this account of what I tried and how it went wrong useful!)

Thanks pal, any help is appreciated!

So at the moment my progress is stalled as i wait for

replacement DDR3 to arrive (my ocz goldies were buggin out),

but i think i understand how to get it working now.

From my understanding i would need to:

1.convert meroy's gfx.plist to hex using gfxutil

not quite sure what "Run gfxutil -f display and change the PciRoot key" means

2.insert the newly created efi string into the boot plist

3.insert 0x05eb10de&0xfff8ffff into NVDANV50Hal.kext/Contents/Info.plist

4.run as root --does this mean opening terminal with administrator privileges?:

kextcache -v 1 -t -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

When my memory arrives ill give it a try.

Hi Rph4 I have 2 dual PCB in QUAD SLI PNY GTX 295 cards in 10.6.1 Retail installation over ASUS WS P6T7 SuperComputer motherboard, I follow your steps but no luck, the mode VESA was better but I can't enable OpenCL / QE / CI, .I m desperate so please please please let me a anti-idiot guide step by step , I m very frustated with me computer. i was saving for a long time by buy it....

hackdan · November 14, 2009

I appreciate all that you guys are doing, but this isn't very noob-friendly at all.

First I see appending the NV50 file with those strings, then another saying don't worry about it because a kext fixes it.

Could someone graciously write a step-by-step? Hell, I'll paypal somebody a few bucks if they wanted. haha

Hey check this is very long but i have a advance .... I think.... wherever maybe in short time we have the anti-idiot guide of ours dreams!

meroy · November 16, 2009

hackdan, go here for more noob friendly post. I'm not able to monitor these posts. I hope this will help you.

You have a dual-pcb gtx 295. My plist will not work with your card as I have the single pcb edition. My plist doesn't have the @2 entires that may be needed by your card(s).

2 merroy:

good seeing you keeping up with GTX295 help - thanks a lot.

I've translated your guides to Russian mac-forrums for those how have 295, however 10.6.2 changed the situation - strings are no longer working in boot.plist and only way to boot back after the update is to remove strings, so the result is - basic mode with efianabler.

I want to belive that you fix it somehow (at least for single pcb you have), so could you make a guide for 10.6.2 users?

The strings continues to work for me under 10.6.2. Go here: http://www.insanelymac.com/forum/index.php?showtopic=184318.

My current plist is posted there. Did you remember to add the pci id to NVDANV50HAL? Not sure which card you have single or dual PCB design.

There is no need to add the PCI ID if you install NVGTX295.zip from this post:

http://www.darwinx86.org/guides/installer-...280#comment-284

This zip file contains a kext: NVGTX295.Fix.zip. Add this to your /Extra/Extensions/.

thanks a lot meroy - it woks!!! i completely forget about device id (i have single pcb). I'll let guys from http://www.applelife.ru know as well.

I tried both ways - add id to NVDANV50Hal.kext & NVDANV50Hal.kext and by adding NVGTX295.Fix.zip to Extra. Both OK!!!

ANARCHiNTOSH · November 21, 2009

hey everyone, ive written a complete noob friendly guide explaining meroys method and created a pack containing everything you need to get it working

i also translated Raph4s kext instructions, which is attached to my guide.

mmm noob friendly guide

meroy, whats the lowdown on dual monitor mode? its not working on my installation but ive heard other people have had success. i just get two black screens when i plug in my second monitor. hmm.

meroy · November 22, 2009

meroy, whats the lowdown on dual monitor mode? its not working on my installation but ive heard other people have had success. i just get two black screens when i plug in my second monitor. hmm.

Try the following for the NVCAP value: Look for NVCAP in your plist file and replace the value with this one for both PciRoot entries in your plist file. This will enable both displays for your setup.

BQAAAAAAAwAMAAAAAAAACwAAAAA=

I don't think it's possible to come up with one plist template to accommodate both the dual and single PCB designs.

Congrats on making your GTX 295 card work under SL. The value above will complete your setup and allow you to use 2 displays. Remember to breath when you see both displays enabled under SL.

Nvidia GTX 295 support
