Problems on Upgrade to Yosemite with GA-H97-HD3 - HD4600 gets 7MB memory

[godber]

So I m in trouble with my kids. I took a pretty rock stable Mavericks Mackintosh build and ran the update process for Yosemite. Since then I have not had a usable system.

I am using Chimera on EFI boot loader and have updated to v4 (I believe - the message at the boot screen says something about v2.2 but I believe that is the base version of Chameleon?).

The only way I could get a boot is to specify IGPlatformID=0d220003 which I believe is the default anyway. I also have to specify "Graphics Mode"="1920x1080x32" to avoid getting a screen res of 1024x768.

I have now run Multibeast and can boot the system with no input after manually adding the IGPlatformID to my boot parameters.

Problem is the system is slow and the screen is flickery. I think this is because the system reports just 7MB of video RAM which I have seen reported elsewhere but can see no real fix for other than setting the IGPlatformID.

I also notice that Multicast seems really sluggish (even though system monitor does not seem to report any real CPU hogging.

I have not made any changes to bios or system config since the Mavericks build.

Gigabyte H97-HD3, Intel i7 4770k, inbuilt graphics (HDMI), Inbuilt ehternet and audio. 240GB SSD boot drive, 3TB Hard Disk. 16GB memory.

I have checked that Vt-D is disabled in bios

I have also added the IGPlatformID to org.chameleon.Boot.plist with a value of 0d220003

In addition to the screen flicker I get some panics after a random period of running with the feed zone element has been modified in chalk.64 error with the expected deadbeaf stuff. Kernel module causing the panic varies.

I have reinstalled the 10.9.3.9 AppleIntelFramebufferAzul.kext

Can anyone shed any light on this?

I would change your Multibeast config and remove 3rd
Party Sata and the Intel Graphics Patch then reboot.

Cheers Len, I had already taken out the 3rd Party SATA after studying the description late last night. System was more stable but still poor performing graphics. I will check your other suggestion tonight.

I am now booting with those two items removed. The system appears more stable , I will run the system overnight to see what happens. (Spoke too soon, just crashed after 2 minutes of up time)

The system still only recognises 7MB of video memory.

The verbose boot log shows:

--------------------------------------------
----------INTEL DEVICE INFO ------------
---------------------------------------------
Class Code [0300]
Intel Graphics HD4600 [8086:0412] (rev 06)
Subsystem: [1458:d000] :: PciRoot(0x1)/Pci(0x2,0x0)
Using default ig-platform-id of 0d220003

HD4600, do not select.

HD4600, do not select.

Thanks for the response
I have removed this now. Maybe a slight increase in stability but still only 7MB of ram for the Video card!

I have the exact same problem. If anyone can help I would greatly appreciate it.
