Updated three of mine from Lion to Mavericks, skipping ML. It took some effort as I did not do fresh installs, but now they work great. Here is my report (using the User DSDT method):
1. GA-P35-DS3R, Q6600, 8GB, ATI Radeon 4870
- initially, I was not able to boot into UniBeast, regardless of the boot flags I tried
- copying DSDT.aml to the hidden /Extra folder of the UniBeast USB drive helped
- I now use these flags: GraphicsEnabler=Yes, IGPEnabler=No, npci=0x2000 and PCIRootUID=1
- Audio -> Without DSDT -> ALC885/889a works
- MultiBeast 6.0.0 install failed when first tried; I had to remove several .kext packages from /System/Library/Extensions for it to work.
- Lesson learned: it makes sense to rename or remove the existing /System/Library/Extensions folder BEFORE attempting the upgrade.
2. GA-EP35-DS3L, Q6600, 8GB, ATI Radeon 6870
- no issues booting into UniBeast
- it's fine to have GraphicsEnabler=No
- Audio -> Without DSDT -> ALC888 Current v100302 did NOT work
- Audio -> Without DSDT -> ALC888 Legacy v10020 works
- MultiBeast 6.0.0 install failed at first; I had to remove several .kext packages from /System/Library/Extensions for it to work.
- Lesson learned: it makes sense to rename or remove the existing /System/Library/Extensions folder BEFORE attempting the upgrade.
3. GA-EP43-UD3L, Q9300, 6GB, ATI Radeon 4870
- initially, I was not able to boot into UniBeast, regardless of the boot flags I tried
- copying DSDT.aml to the hidden /Extra folder of the UniBeast USB drive helped
- I now use these flags: GraphicsEnabler=Yes, IGPEnabler=No, npci=0x2000 and PCIRootUID=1
- Audio -> Without DSDT -> ALC888 Legacy v10020 works
- renamed /System/Library/Extensions before starting the Mavericks install, so everything went smoothly!
Thanks for the excellent tools!
