Hi All!
Yesterday I was trying to install Mac OS X Lion 10.7.2 iAtkos L2 on my Lenovo T61 with Graphics Adapter Nvidia NVS140m.
When I inserted the DVD and pressed F8 I typed the following commands: cpus=1 GraphicsEnabler=No PciRootUID=1.
It loaded and I formatted the Disk and the installation began. At the end of the installation the laptop powered off itself. I didn't  press any button or something similar to interrupt the process. When I tried to power on the laptop it just beeped 1 long time and 2 short times. I searched the Internet and understood that this is caused by a GPU failure.
Now the question?
IS it possible that I broke down the laptop with my commands (cpus=1 GraphicsEnabler=No PciRootUID=1)???
Please share your opinion!!!

Boot only with -v(Verbose)forget any command like-cpus=1 GraphicsEnabler=No PciRootUID=1
if not boot with -v .press only Enter(no command)to boot

OK! So what do you think?
Did I messed up my laptop with these commands or it was just its time?

Well, I see you are deeply into the Hackintosh stuffs, so what's your opinion? Is it possible to actually destroy a GPU with these boot flags?

[Lejenk]

A GPU will not be destroyed by giving some boot flags. Could be that it just was the cards time.
The beeps you described could identify one of the following problems:

• System board
  
• LCD assembly
  
• DIMM

Time to sent the notebook in for repair if the problem persists.

Hello, Lejenk!
My personal opinion corresponds entirely with yours, but I bought the laptop this afternoon (second hand) and I couldn't believe its just a bad luck ( I used it not more than 1 hour)... that's all
I really hope I didn't make something stupid with these boot flags!

[Lejenk]

You did not, just a hardware error, has nothing to do with the installation of OS X.
Good luck.

Little update!
It turned out that the problem is caused by the faulty GPU. I powered on the laptop and covered it with a blanket. After a while it powered off itself due to the high temp. And voila, it's working. And I installed Windows and it worked. Then I decided to reinstall Mac and give it another try. I used iAtkos L1 and everything was just fine. Today I used the same iAtkos L2 as I used yesterday before the failure and tried to install it (I didn't use any boot flags this time). After the installation the laptop restarted itself and guess what, it failed again (three beeps). I really don't know what is wrong with me or the laptop but it sounds a little too strange to be a coincidence. I am really confused!!!

I start thinking that iAtkos L2 DVD caused this malfunction.
