Sorry for the loong post. Hopefully it will help someone with a temporary solution to start additional research.
Admins/Devs :
We still would like a DSDT fix, if that is possible.
I got Lion 10.7.3 to work with this board [Asrock Z68-MiniITX] + Zotac Nvidia 520 Graphics [single slot card]
. The installation can be done without the graphics card [I have an Intel i5-2400 processor with HD2000 Integrated Graphics
]. But you need an additional [working in OSX] graphics card to boot normally and get good resolution.
I used the following Boot parameter combinations :
With Intel HD2000 only [UEFI set to default to Onboard graphics] :
USBBusFix=Yes EHCIaquire=Yes [Optionally you can add '
UHCIreset=Yes' if u still get stuck]
With the Nvidia 520 card [UEFI set to default to PCI Graphics] :
USBBusFix=Yes EHCIaquire=Yes PCIRootUID=0 GraphicsEnabler=Yes
[PCIRootUID=0 was mentioned in one of the Posts on the web, donno where. It is a fix for booting into a regular welcome screen to fix the slow as hell welcome screen or the white screen with a
]
I optionally chose to boot in verbose [Boot param
-v] mode to be sure to know where the system stalled [if it did]. So far almost all of the time, the above Boot parameters worked.
Post install, you can boot using the
Intel HD2000 card only in safe mode [Boot Param
-x] with horrid graphics,
if at all that works.
Post install setup [Multibeast], I installed
Sound > VoodooHDA ver. xx.7.2 [the highest version caused kernel panics]
Disk > IOAHCIBlockStorageInjector
Miscellaneous > ElliotForceLegacyRTC, Ev0erboot, FakeSMC, NullCPUPowerManagement, USB 3.0 NEC/Renesas [donno if it worked]
OSx86 Software > KextUtility, Show All Files
Do not install the FakeSMC Plugins, as they resulted in kernel panics.
Note : Everytime I installed,
Ethernet worked OOB [from a win7 install, I found it was a Realtek card. Even tho multibeast had the option, I DID NOT check/install any network devices thru it, b'coz it was working already]
Other Notes : I have a Multi boot setup for Lion and Win7 on a GUID partition to utilize EFI booting, but so far I've hit a brick wall
on loading a Boot loader to the EFI partition. Everytime I install Chimera/Chameleon it creates a hybrid GPT/MBR which would load OSX but not Win7 [coz there is no Win7 MBR bootloader installed, being on a GPT disk
]. Right now I boot to win7 using the UEFI shell and OSX via the Uniboot USB drive.
If anyone does decide to use MBR over GPT [enable the 'Boot from Legacy ROM' option in UEFI Bios setup], I don't think you should jump any hoops, other than following ur regular procedure. After installing Chameleon/Chimera, don't forget to edit the
com.chameleon.boot.plist with the previously mentioned boot parameters.
If anyone has a solution to install any bootloader to the EFI partition so that UEFI can default boot into it, with working options to boot Lion and Win7, please help me out.
