Snow Leopard 10.6.8 On Lenovo G770 i5 Sandy Bridge Laptop

2012-08-16 Prepare and fix dual boot for lenovo.

And always use portable drive to install before internal hard drive. For Realtek id 0139 card reader isn’t supported, a USB SD card reader is handy.

May 17, 2012 If you’re not familiar with chameleon, there’s a way to dual boot using windows 7 and EasyBCD on 750GB hard drive here.

2011-12-26 For those who want to boot from WDC 750 GB, I use the original MBR formatting on the hard drive, use Windows 7 to shrink a partition for Snow Leopard 10.6.8. Use an external USB hard drive to load Snow Leopard 10.6.8 or LION first, then restore the partition to the internal hard drive partition. When done, remove the hard drive, connect this hard drive to an external USB, install Chameleon on the 100MB MBR partition, copy the Extra folder to this MBR partition (after Chameleon installation). Make sure we can still boot the drive (in USB connection), then put it back to the LAPTOP, it will boot using Chameleon boot loader.

I’m writing up a tutorial on how I intalled Snow Leopard 10.6.8 with full QE/CI/CL & resolution 1600×900 & Atheros Ethernet/Wifi & sleep working on my Lenovo G770 10372LU laptop model. I need these software to make it work. I think this laptop is the best for Snow Leopard 10.6.8 and Lion at the moment. This Lenovo has the important devices that work/not work with Mac OS X at the moment, please identify your hardware because G770s do come with different devices. Check for Graphicsid, Wifiid, Ethernetid, SDcard readerid. My SDcard id is not supported at the moment. Thanks to many techs savvy on the net like Maldon, Bcc9, I could get these going so well. MAKE SURE TO BACK UP THE IMAGE OF THE HARD DRIVE BEFORE DOING ANYTHING TO THE LAPTOP.

Software and hardware needed.

* iboot-legacy, multibeast, updatehelper

* An external USB hard drive: we will need this one over and over for installation, experimenting snow leopard 10.6.8 and lion then restore it to the internal hard drive after we’re happy with our MAC OS X. DON’T install on the hard drive without knowing if it’s going to work.

  • Cool, thanks very much.

    So i am going to put the 750 inside the 770
    Partition the drive in 2
    Install Windows on the 2nd partition?
    Then take the drive out put it in USB enclosure
    install osx
    Put back in 770
    all good?

    • I don’t know if you can do it now since you already format with guide. You have to partition the whole drive to mbr. Only 2 partitions, 100mb and the rest is windows, try to make it the same as the original drive. Then use windows to shrink the partition for snow leopard

    • Well, I have an actual Windows 7 64 Ultimate disk. If I put back in the 750 and run the Windows installer and use that to partition the drive, will that over write the boot sector?

      Im just confused the order to do things.

    • Do you know what partition you have on your drive right now? GUID or MBR, use your usb mac to check, windows 7 will create a 100mb boot partition on an MBR drive automatically, it it does that, then you’re done, because the bios will boot windows from this MBR 100mb partition.

    • Right now, it is one partition exfat with a master boot record.

      From what I would install Windows 7 and then shrink the partition. I know windows 7 will make that 100 mb system partition.

      Then after Windows 7 is installed I shrink the partition leaving some free space for OSX?

      Then put it in a usb drive and install osx?

    • EDIT

      Right now, the 750 is one partition exfat with a master boot record.

      From what I understand I would install the drive into the g770.
      Install Windows 7. I know windows 7 will make that 100 mb system partition.

      Then after Windows 7 is installed I shrink the partition leaving some free space for OSX?

      Then put the 750 into a usb enclosure and install OSX like last time?

    • Leave the 750 in the laptop, restore from the USB 160gb drive to it, then remove it and load chameleon onto the 100mhb or you can put it on usb and install mac osx on it, it just take longer than using restoration.

  • Hi idog, i have lenovo G570GH it’s almost the same i5 2310m, but 15.6″ 1366×768 resolution, your dsdt.aml have torbo boost support because i test it with cinebench and i saw that the performance was way bellow windows7 performance. I saw this link on tony
    //tonymacx86.com/viewtopic.php?f=259&t=42503&start=20 but i don;t know if it’s working. Thank you very much.

    • Dragos,
      If the display is good and not tearing, artifacts, then the dsdt.aml is working. About the performance, you have to compare it with other Mac OS X and not with Windows.

      Cheers,

      idog

    • I have the same configuration as you, i5 2310m 2.3ghz, 8gb ddr3 1333 2x4gb Corsair, Intel HD 3000, if you ran a bench like cinebench or geekbench
      //www.primatelabs.ca/geekbench/ tell me what score you have to compare it with mine. Thank you.

  • Having installed the UpdateHelper, rebooted, installed the 10.6.8 combo, installed MultiBeast, copied the Extras_fixed.zip file to the Extras folder (bit of a pain as I was getting a “The operation can’t be completed because you don’t have permission” error when trying to copy them – I drag/droped them instead) and having run Kext Utility to update the cache, I rebooted and the boot hangs on “[ PCI congiguration begin ]”.

    Where di I go wrong?

    • I’ve seen this one before, but I forgot, since there are new multibeast and chimera, the best is to try to get the old chimera 1.5.3 or 1.5.4. Are you installing 10.6.8 directly to the hard drive or USB external drive?

    • Installing to an external hard drive. I’ve switched to trying to install Lion, but that’s not going too well either (as you’ll see here: //www.dognmonkey.com/techs/install-lion-on-lenovo-laptop-without-snow-leopard-using-unibeast.html#comment-521)!!

      I’ll try giving it a shot with the older Chimera versions.

    • Hello Tom,
      I just re-installed my laptop with LION and updated it to 10.7.3 with facetime working. It’s so easy and fast. I’ll write it up soon.

      Cheers,

    • I would just like to say, thank you SO MUCH for this. I am using an Asus N53SV laptop, with Core i7-2630QM processer and HM65 bridge. Using your DSDT and the EFI string within your com.apple.Boot.plist, I was able to enable full resolution and QE/CI in 10.6.8. I have been trying for months to get this to work. Again, thank you so much!
