get OS X running and able to boot from EFI partition on HDD. clover installer can't install itself to ESP, so i have to do it manually.
but I still can't get audio working. I'm sure i installed DummyHDA.kext using kextwizard and fix permissions.
Also EVERYTIME i successfully boot into OSX, my BIOS will change Optimus to disabled. So next time, when i reboot or shutdown->powerup, i have to go to BIOS and enable Optimus then reboot again to make everything working. couldn't figure out why

update:
sleeping is not working. trying to switch to chameleon according to Jake's guide
