DSDT on Toshiba P770

[sanjayrup]

Hi all,

Sorry for my bad english, i'm french, but i will try to explain my problem.

I have a Toshiba P770, with HM65 chipset, HD3000 (0116) & Nvidia Optimus GT520M.

I can only boot with GraphicsEnabler=No & smbios.plist Macbookpro 8.1, and remove all Nvidia / HD3000 / AppleIntelHD* kext.

Then i have a 1280x800 resolution, with QE/CI but i have a lot of mouse lag, and my intel HD3000 is only 64Mo.

If i boot with HD3000 Kext (ML 10.8), i have 1600x900 screen (512 Mo), but screen is very big, and only have half screen.

is there a solution with DSDT ?

I have extract my DSDT with AIDA64 on Windows, rename into DSDT.aml, and put it in my Extra Folder, but no change.

Can i hope any help ?

Thank you a lot !

sanjayrup, HD3000 should work fine using the attache DSDT.

There is a method to disable the GPU by adding some SSDT codes to DSDT file, never done it. But if you search google sure you will find something about it.

Use latest Chimera 1.11.1

Graphics Mode key>

1920x1080x32 string> (Your screen res)

GraphicsEnabler key>

Yes string>

[sanjayrup]

Chimera is already the lasted version.

Reading DSDT.aml OK, but same issues

But can only boot with GraphicsEnabler=No !

Without kext => 1280x800 laggy and 64 Mo

With kext => grey screen with mouse extra zoom

Test the laster FakeSMC but nothing

if i boot with GraphicsEnabler=Yes i have

Nvidia GeForce GT520m 0MB NVd9 [10de:1050] : : Pciroot(0x0)/pci(0x1,0x0)/pci(0x0,0x0)

 

Edit: smbios macbook pro 8.1 doesn't boot, only smbios macbook pro 8.3 (to correct my first post)

Edit2: I think that i must patch the DSDT to disable nvidia optimus because i can't disable it in the bios but how to, that is the question

[sanjayrup]

Here is my ssdt-7.aml where i think that i have a Nvdia text

ssdt-7.zip

This is the link that tells about how to disable the NVIDIA GPU.

I can see there is a Method OFF on the SSDT you have attached, but I'm really not sure how to add it but im pretty sure experts here will be able to help you.

Sorry, That method don't work. I can see people in the comment struggling as well.

sanjayrup,

Keep an eye on this thread. These people have successfully disabled GPU. I have asked them for help and attached the DSDT and SSDT.

Hey !!!!!

With HD3000 kext & DSDT, i have 1600x900 and 512Mo HD3000 Graphics, with transparency !

BUT mouse lag is still here maybe is a different issues ... speedtest or nullcpupowermanagement ?

[pmdsp]

Wow gr8...

Get proper kext from osx86.net. Also as told by artur-pt above read the hd3000 thread using google translate. There is more info then just the hd3000 patch.

[sanjayrup]

if i remove HD3000 Kext, i'm with 64 Mo Graphics and 1280.

i will try with smbios macbookpro 8.1 ! i'm with 8.3

[sanjayrup]

Hi friends !!

With cpus=1 all is working fine !!!

What can be the problem ?

Edit: SOLVED !!!! with voodootscsync.kext and editing info.plist !

[sanjayrup]

Hey. All is working fine !!

Only issue with my Wireless Realtek RTL8188CE. So i change my wifi card with a atheros AR9285 168b 002b (wife's computer).

Now i need to patch my DSDT for Atheros AR9285

http://osx86.co/f36/atheros-ar9285-0x002b168c-fix-for-snow-leopard-t6662/

[pmdsp]

2 ways to get the wife card working. Use a edited kext or add DSDT edits.

I have the same wifi card and i have managed to get it working with DSDT edits with the help of this forum.

Run IOReg and save it with no extension and attach it.
