Is there any way to get the source for this kext and recompile it as 64-bit? I'm interested to try, but just curious if it has been done yet. I hate to reinvent the wheel.

 

I don't think anybody has tried. We'd know by know. Go for it. That'd be reallly incredible if you can do it and I'd make you my hero :)

stock gma950 driver works fine in 32bit mode. in order to use the max resolution . i fixed it using this guide

 

http://www.insanelymac.com/forum/index.php...&start=380#

 

 

it fixed everything except for the sleep function but i also got it working using SleepEnabler.kext.zip

 

 

NOTE: You also need to edit your com.apple.Boot.plist

 

and add this code below your Kernel Flag "arch=i386" without quotation

 

it will lo0k exactly like this

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Kernel</key>

<string>mach_kernel</string>

<key>Kernel Flags</key>

<string>arch=i386</string>

</dict>

</plist>

 

h0pe that helpz:D

I assume you got a desktop. gma950 on notebooks may not need a patch at all, just EFI string in c.a.boot.plist (see post 24 above and link)

btw. arch=i386 will not work this way in boot.plist. it needs to be a key

<key>arch</key>

<string>i386</string>

otherwise it will boot into 64 bit provided your cpu is 64bit, e.g. C2D. I got this from kabyl at voodoo.

yup i'm using desktop. arch=i386 below the kernel flag work fine for me. i'm using c2d

If its a notebook, your best shot is a EFI patch

If its a desktop, you should try the DSDT fix posted somewhere for 950GMA and Desktops.

 

I'm on a laptop and I can use stock Snow Leopard 950gma kexts fine but I HAD to use the EFI patch.

So you have Chameleon installed on the EFI partition and the com.apple.Boot.plist with the string in is the Extra folder there? that's the only place you have to put the string? Can you post the complete contents of your plist file?

 

I heard the DSDT patch does not work on the mobile chipsets?

 

 

Yes it does. It works perfectly with an external monitor on my D620 - no kexts needed. However, with that setup I can't use the laptop display - so - I use the ancient framebuffer and it's good. I haven't noticed artifacting with Snow yet.

 

 

My boot/post install should work on almost any laptop with GMA950 for Snow Leopard.

 

You can link to it from my tagline.

i have tried to run sl with my gma950 27a2 (hp 530 notebook) with efi string (works perfectly under 10.5.8) but it doesn't work on snow leopard :(

 

Where did you get the EFI string? I have the same graphics card in my hp dv6000 and am running sl but cannot see DVD video due to graphics card. EFI studio only has nvidia cards.

 

Thanks!

Hello,

 

I'm curious to know what prompted you so write that you HAD to use the EFI patch. I also have a laptop, a DELL E1505 with GMA 950 graphics, and have been trying for a couple of weeks to get my graphics card properly detected using DSDT edits. I have it properly detected when using a device-properties EFI string in my com.apple.Boot.plist, but would like to get it working through DSDT. I have a number of other DSDT edits successfully applied, but I have so far been unable to get my graphics card detected via DSDT edits. I've tried the "Clamshell hack Intel GMA" DSDT edit from DSDTSE, pasted below:

 

Method (_DSM, 4, NotSerialized)
               {
                   Store (Package ()
                       {
                           "AAPL,slot-name",
                                Buffer () {"Built in"},
                           "AAPL,Haslid",
                                Buffer () {0x01, 0x00, 0x00, 0x00},
                           "AAPL,aux-power-connected",
                                Buffer () {0x01, 0x00, 0x00, 0x00},
                           "AAPL,backlight-control",
                                Buffer () {0x01, 0x00, 0x00, 0x00},
                           "AAPL,BacklightRestore",
                                Buffer () {0x01, 0x00, 0x00, 0x00},
                           "AAPL,HasPanel",
                                Buffer () {0x01, 0x00, 0x00, 0x00},
                           "AAPL01,BacklightIntensity",
                                Buffer () {0x4E, 0x00, 0x00, 0x00},
                           "device_type",
                                Buffer () {"display"},
                           "model",
                                Buffer () {"GMA950"},
                           "built-in",
                                Buffer () {0x00}
                       }, Local0)
                   DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                   Return (Local0)
               }

 

I've also tried just leaving the "AAPL,HasPanel" and "model" entries listed above, as those are the only things I have in my device-property string when I use an EFI string in my com.apple.Boot.plist. I've also tried it with "GMA 950" instead of "GMA950", to match my com.apple.Boot.plist.

 

Unfortunately, none of these things lets my graphics card get properly detected.

 

Any help would be greatly appreciated. Thanks!

the following code worked for me in my com.apple.boot.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

<string>-v cpus=1 arch=i386</string>
<key>PciRoot</key>
<string>1</string>
<key>Timeout</key>

<key>device-properties</key>

<key>AAPL,HasPanel</key>
<string>0x00000001</string>
<key>model</key>
<string>GMA 950</string>
</dict>
</plist>

 

now only if I could figure a way to get the card to be read as having more than 64MB VRAM. Doesn't it have theoretically 256MB shared vram?
