i select only x3100

Well, these were the settings I used when installing and is what I suggested to another member here.

 

Bootloader - PC EFI V9

X86 Patches - Decrypters - AppleDecrypt

- SMBIOS drivers - SMBIOS Enablers - AMBIOS EFI Air

- Kernel - 9.2.0 Kernel ToH (should work fine I think)

- ACPI - X86 ACPI (just to be safe)

- Disabler.kext

- Remove PowerManagement.kext

- Remove Thermal kexts

Drivers - select the Graphics Update plus the drivers for your card.

System - SATA - select the one for your HD

- Speedstep - Inel Speedsep b (just like the app that comes with it better than the one from the "a")

- Network - well, I would select all of them in case you change the LAN card or something.

 

Now, the error you got has to do with the HD (i think). I selected the Intel AHCI SATA for mine. Not sure what yours is, so either search it (if you don't know already) or use this setting and pray :).

 

Hope this helps.

That battery display is not a problem for me since I am always on AC and actually never bothered to look for solution. As for the sound I can not help you here since we have different sound cards. Search the forum, maybe someone has custom drivers for your card. If not, either use a USB solution for sound (if it works) or you have to wait. On my laptop I only have sound output and that's about it. Look in the forum for AzaliaAudio and see if that helps.

 

By the way, are you using both cores?

OK, I am currently testing something here, so maybe you can help. Try to boot without cpus=1. Normal boot with both cores. If it hangs, unplug the AC and after 3-5 sec. plug it back in. See if it continues to boot. Try it a few times. If still doesn't work, try to boot on battery. When it hangs, plug the AC in and see what happens. This is how I am running both cores on mine. Sometimes it also boots with both cores if I use "cpus=1, -v". The comma should be there. If you don't mind can you try that out and let me know what happened? Thanks.
