NV GT420M works on OS X 10.6.5 now!

20 posts in this topic

http://bbs.pcbeta.com/thread-819284-1-1.html

 

You might read the original topic if you are good at Chinese. We are the first to crack GT420M on OS X 10.6.5.

 

Spec:

ACER ASPIRE 4741G

 

CPU: Intel Core i5 430M

RAM:2G DDR3

HD: 500G

Graphic card: NVIDIA GT 420M 1024MB

Audio: ALC272

Wifi: AR5B97------not working, already replaced with AR9280

LAN:BCM57780

 

 

software and driver required:

 

1. Chameleon v2.0-RC5 r650

http://www.kexts.com/view/676-chameleon_v2.0-rc5_r650.html

 

2. Nividia drivers geforce 4xx+580 (tweaked by tony) : (NV Mac OS X Driver Release_256.01.00f03 also works, but you need to install it through 3 packages which are extracted from the original pack)

http://www.kexts.com/view/638-nividia_driv...ed_by_tony.html

 

3. Moded DSDT.AML for Acer 4741G

 

Actions required:

1. install Chameleon v2.0-RC5 r650

2. install Nividia drivers geforce 4xx+580 (tweaked by tony)

3. go find GeForce.kext and NVDAGF100Hal.kext in Extensions folder,then right kick each and modify the info.plist by inserting the GT420M ID. By the way, my GT420M ID is 0x0df110de:

GeForce.kext:

<key>IOPCIClassMatch</key>

<string>0x0df110de</string>

 

NVDAGF100Hal.kext:

<key>IOPCIPrimaryMatch</key>

 

<string>

0x0df110de0xffe0ffff

0x0dc010de0xffc0ffff

0x0e2010de0xffe0ffff

0x0ee010de0xffe0ffff

0x0f0010de0xffc0ffff

0x104010de0xffc0ffff

0x108010de0xffe0ffff

0x0e2210de0xffe0ffff

</string>

 

save both after modifying.

 

4. Copy the attached DSDT.AML to Extra folder and modify com.apple.Boot.plist by adding 2 lines into it as follows:

<key>DSDT</key>

<string>/Extra/dsdt.aml</string>

 

 

5. Disk tool------->repair disk permissions. Then restart your computer and see if it works.

 

DONE. You might also try it on GT425M or GT445M to see if it works.

 

PS: Some friends tried this method and found that it could still drive GT420M even if GeForce.kext and NVDAGF100Hal.kext were not modified with hardware IDs.

Hey man. I must say DSDT is the critical part in driving GT420M and this DSDT.aml is only working for Acer 4741G. As far as i know, there are no models with GT425M in 4741G. I have no idea about what your NB's spec is. So i could only suggest that trying to patch your own DSDT until it works.

Thank you k. Iarryonline

 

GOOD NVIDIA GT 415M OK :P

 

 

Good job! Did you change the Graphics info into GT415M on your own? Smart guy. I forgot to mention that the GT420M hardware info was fixed in DSDT.

Would you think your method would work with other computer models as well? I have a Dell XPS 15 with the same graphics card, maybe your patch will work for me as well? (Without the DSDT part of course, because it is model-specific)

Without modding my GT 420M only shows with 512MB even though it has 1GB.

 

Will try modding later.

Did you find out how to get the full 1GB recognized?

Hi,

 

is sleep working and wakeup working?

 

I would like to buy this laptop too, but it seems they changed the name of it. In Germany i found only a laptop named

Acer Aspire 5742G-5463G50Mnkk. The parts are the same.

 

Here is a ebay link, please have a look at it and please tell me if it is your laptop.

LINK

 

Thank you very much,

 

Alex
