ML on a Gigabyte z77x-ud5h with HD4000

[McGonSpeed]

Hi Guys!

Today I downloaded Mountain Lion from the appstore and put it on a 8GB USB stick via UniBeast 1.5.0
The install was super easy. Nothing to do. Everything is working out of the box.

I Made sure the bios was default and had everything on AHCI. Removed all RAM sticks except 1 of 4GB and put 1 HDD drive in there for install. I installed from a USB 2.0 port connected to a header on the motherboard.

Everything is working great out of the box. Even my Firewire M-Audio ProFire 610 is working like it supposed to!

But the only thing is my HD4000 iGPU is displaying 1024x768. I would like to put it on its native resolution of 1920x1080.
I connected my (HD-TV) via DVI->HDMI connector. I think a straight connection to HDMI will work as well.

Since HD4000 is supported in ML, why am i not getting the full resolution ??

(My bios setting says 128MB of shared video memory. ML says only 64MB)

Thanks guys! Have a good one!!

Are you using GraphicsEnabler=Yes or No in your org.chameleon.Boot.plist? This file is found in your /Extra folder. Also, try connecting to a DVI monitor if you can. Set the BIOS to 384mb shared mem if you're using 4GB, 480 or 512 (if you have the 512 option use it, otherwise use 480) for 8GB or more.

Seems like i don't have the "org.chameleon.Boot.plist" file.
I checked : /Library/Preferences/SystemConfiguration for config files, but did not find any. I'm still kind of a noob at this stuff. I know there is/was a tool called chameleon, but can't find it at the downloads and don't know if I still need it.

Thanks for your reply!

It's in System/Extra/

I got full resolution to work on the same motherboard by adding this string to the org.chameleon.Boot.plist

<key>device-properties</key>
<string>8800000001000000010000007c0000000200000002010c00d041030a000000000101060000027fff0400100000006d006f00640065006c0000001a000000496e74656c20484420477261706869637320343030302c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000005006201</string>

Sounds like the HD4000 kexts are not loaded.

You are most certainly using Chimera 1.11 and therefore don't need phybron's mentioned string. Just set GraphicsEnabler=yes in your org.chameleon.Boot.plist. But you have to set the correct graphics memory size in BIOS. The size you are seeing in OSX is your DVMT memory size and is set automatically according to your installed amount of RAM, you should set that to MAX in BIOS. Set your "Internal Graphics Memory Size" in BIOS to 64MB.

Why 64mb rather than 384mb?

 

[dta]

Because Chimera uses AAPL,ig-platform-id property which tells the driver what port configuration etc you have. The available properties are listed here: http://www.tonymacx86.com/lion-desktop-support/57184-intel-hd-4000-native-driver-info.html

Now it looks like that for default Chimera uses 01660009, but I'm not sure yet. You have to match your platform-id with the correct VRAM settings otherwise you will get graphics errors.

Thanks for the info, that may really come in handy while trying to do some troubleshooting/hacking tonight.

I wrote a guide how to enable HD4000 because a lot of people seem to have issues:

Ah... I updated to Chimera 1.11 earlier today, so just removed the string and it works fine. Thanks.
