On my Sony VGN-NR220E I have installed iATKOS v5i and installed with these settings:

 

Main system

Netkas PCEFI V9

Appledecrypter

smbiosenabler

disabler

Voodoo kernel

remove powermanagement

ps/2

OHR

Remove thermal kexts

intelSATA

INTEL AHCI sata

graphics update

Laptop battery

 

Once I installedl, I boot with -s

Then write:

 

/sbin/mount -uw /

rm -R /system/library/extensions/AppleIntelGMAX3100FB.kext

Exit

 

Then I go in -x safe boot and install the following:

Natit.kext

AppleIntelGMAX3100.kext

AppleIntelGMAX3100FB.kext

AppleIntelGMAX3100GA.plugin

AppleIntelGMAX3100GLDriver.bundle

AppleIntelGMAX3100VADriver.bundle

 

after I do so and then make SwitchresX set to my 1280x800 res I repair permissions and reboot.

 

After reboot it comes up into OS X normally with the correct res but for some reason the screen flickers I don't know why. any ideas?

 

and I know someone said something about the kexts above and making sure they match your hardware IDs. Is there a way to change them to match, or do they have to match?

I do not use SwitchresX and my graphics is perfect.

All my kext IntelGMAX3100* version 1.5.36 but 3100FB is 1.5.18 - the only working for me.

 

Thanks for your advice. The same worked for my Acer 7720. QE + CI and native resolution. Ideneb 10.5.6.

 

Any idea how to fix the newer 3100FB? It would save a lot of confusion.
