  1. Hi Herve, I will create the step by step this weekend as I will be installing it for my friend so I can take the screenshot along the way
  2. This is what i get,,, the serial always using Lenovo instead of the one inside SMBIOS http://postimg.org/image/ti5mq3wzb/full/
  3. I got it working now... Now the serial keep showing my Lenovo real serial number... I cant change it, manually or using chameleon to generate all not work, anyone know how to change the serial number???
  4. sry misread the message, I use the myhack to create the USB install, using the extra i found here http://forum.thinkpads.com/viewtopic.php?f=32&t=105334
  5. Hi I have successfully install Mountain Lion 10.8.3 on my x220, at least all basic things are function... however... I can only boot using the USB drive (the installer), select my HDD than can boot, else it will display menu for me to choose which HDD to boot up, no error message. I tried install Chameleon but still same, I am using the GUID table during installing the OSX. The HDD only have single partition. Please assist and help... I dont wish to carry the USB drive just for the sake of booting the laptop...
  6. Installed Mountain Lion, update to 10.8.2. Xcode working, bluetooth, wifi, webcam working, app store, mail, wwan working... VGA out to TV don't work, SD card reader and HDMI also dont work.
  7. I finally boot to the installation screen on E6220 mountain lion... Steps to do: BIOS set the CPU XD to enable... its off by default... Lion will work with this off... dont know why Boot with: -v GraphicsEnabler=No I been trying so long to find this but well it work now
  8. Successfully update to 10.7.5, connect to my extra apple magic mouse and work perfectly. I still want to run mountain lion on it... sigh...
  9. Now i dont get the bios read error, but after the long text scrolling, it will just reboot... on the lion install it should go to the mac os install screen. ML just reboot here before the os install screen... please assist...
  10. ok everything including WWAN running perfectly now, have not test SD card reader, smart card reader, hdmi, vga other than that everything is fine... Mountain lion still unable to work... still trying using another HDD...
  11. ok keyboard and bluetooth resolve, now is just the WWAN...
  12. I manage to install Lion today ML still show the same error as my previous post... finally... but everytime i reboot it prompt to connect keyboard although the keyboard work.. anyway to stop it prompting? also the network showing my wifi as bluetooth and the real bluetooth is missing anyway to correct it? i have wwan too and i dont know how to get it work anyone know?

    hi

    yes trying to install ML, sata is in ahci, boot mode not in uefi too.
  14. Hi I have tried all USB ports on e6220... also try a few diff brand of USB drive (sandisk, sony, kingston) re-create a few times per usb drive to test all USB drive also test and scan with no error... bios i using the legacy not the uefi thing... i even remove the 3g, wifi, bluetooth, remove ram and using only 4gb, and using another laptop's ram... hardware test all report ok, also have tried on 2 diff hdd drive... disable all additional stuff like esata and so on... bios setting i follow the myhack guide which enable the c-state, etc... All gives me the same error as ebios read error Controller or device error... worst i cant really find much info on ebios error... most just point me to ebios error, read error which isnt the same as what i get... my 6220 is using bios A08 is that any issue??? Appreaticate if anyone know what is going on... One last thing, the keyboard i swap with a 6420, just like the pointing stick... but i saw someone else also did that and no such error so i not sure if its due to the keyboard or not, and there is no keyboard for me to swap back to test it now...
