Success at last with MSI P45 Neo2-FR! From not being able to even boot (KP right after choosing boot partition) to running in x64 mode for hours now
It wasn't much about the installing from USB, just the other steps and attached kexts i guess. I tried to restore the install dmg to a temp partition (second on the disk) and boot from it but installer failed due to my MBR partition scheme.
Ended up back in a working Leo environment (Chameleon RC1+EFI 10.1) which is my first partition. Installed from there using modified OSInstall.mpkg to work with MBR. Basically what I've been doing for like 10 times already after reading the other guides floating around. Although this time it worked. It must be the fact that I didn't install any bootloader onto the target partition (third on the disk) and just copied the attached files into Extra folder I created manually. I did set the Snow partition active so that my bootloader will know which partition to boot by default and load the correct kexts.
/Extra/Extensions:
Disabler.kext (not sure I need this.. copied from main partition)
fakesmc.kext (by netkas)
dsmos.kext (attached in Snow.zip, maybe I should delete now?)
NullCPUPowerManagement.kext (attached in Snow.zip)
OpenHaltRestart.kext (attached in Snow.zip)
PlatformUUID.kext (attached in Snow.zip, editted accordingly)
/Extra:
DSDT.aml (by DSDT Patcher 1.0.1e. DSDT modded in bios too (fix for cpus=1 in Leo))
com.apple.Boot.plist (copied from main partition, editted accordingly)
simbios.plist (attached in Snow.zip, editted accordingly)
Booted fine first time with -v -x32 switch. Previously, I was stuck right after the first few lines of boot. Ok as expected, KP after finishing registration. Disk Utility gave no installed packages error too. No big deal. At least I got a SL environment up and running.
Booted with -v -s -x32 next time. Repaired permissions. Deleted caches and rebuild.
Code:
chown -R root:wheel /System/Library/Extensions/*
chmod -R 755 /System/Library/Extensions/*
rm -R /System/Library/Caches
kextcache -v 1 -t -l -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions
kextcache -v 1 -t -l -m /Extra/Extensions.mkext /Extra/Extensions /System/Library/Extensions
Booted with -x32 again. System appeared to be more stable. Installed BSD.pkg from temp partition to repair system files. No more "No installed packages error" by Disk Utility.
Booted with -x64. Been running flawlessly ever since!
