Probably no. Y450 BIOS may use another set of BIOS variables with different number IDs. Check Y450 topic created by you at this forum. I've asked you the question there.

Hi Middleton,

 

Thanks for your work on this. I attempted it last night on my Y550 with P8600 processor and once the OS was loaded, it just seemed to lock up the machine. In regards to a previous post, I'm not sure how resetting the BIOS to it's default enabled VT for that user, as when I tried that, it reset the 0378 and 037B bits to 0? Any ideas on what the issue could be?

 

Regards,

 

Steve

About Setup Defaults. Already the second  Lenovo Y550 owner sent me email where he write the following:

after typing "save" in command prompt and pressing enter, he pressed ctrl+alt+del and booted into Windows but VMWare still showed him the message that VT is disabled. He did all the same again but after pressing ctrl+alt+del, he came into BIOS setup pressed Load setup defaults and after loading Windows got virtualization enabled.

Frankly speaking it makes me mad. I don't understand how "Load setup defaults" works. If to think logically It shouldn't. But this action do the trick. I dislike when I don't get how something works but in this case I've simply resigned myself.

And as for your problem. You did the procedure but after loading Windows your machine hangs, am I right? If so you can come back to the previous BIOS settings. Boot to DOS from flash drive and type "symcmos -V2 -Unvram.txt". This will return your previous settings. And also write please how exactly you did VT enabling procedure, step by step.

I've already restored the BIOS, Thanks! As for how I enabled the VT, I followed your procedure to the letter. I did this a number of times. I did a dump of the nvram to confirm that the bits took and that the "Load Setup Defaults" wiped the bits. I would be more then happy to work with you to get this working.

OK. First of all let me explain some things. After the analysis of BIOS I found code which performs VT initialization. BIOS enables virtualization if it finds VT capable CPU and if two BIOS variables (0378) and (037B) are not equal to zero. So we have to change values of these variables from zero to one. To do that we will use the official Phoenix utility symcmos.exe so don't be afraid.

Here is the guide how to do that:

- create bootable flash media.
- download archive "VT-Lenovo_Y550.zip" from here.
- copy all files from archive on the flash drive.
- boot from flash media to DOS.
- at the prompt type "dump" and press enter.
- a file "nvram.txt" should be created and you'll see text editor window.
- find (0378) and (037B) in text and replace their values from 0 to 1.
- if you cannot find (0378) or (037B) then type it yourself;

  here is the example how it should look:

  ........

  (035A) [0002]
  (0369) [0000]
  (036C) [0000]
  (036F) [0001]
  (0378) [0001]
  (037B) [0001]
  (037E) [0000]
  (0381) [0000]
  (0384) [0001]

  ........

 

- press ctrl-F2 and save the file as "vt.txt" (nvram.txt will keep your original settings).
- close text editor (press alt-X).
- at the prompt type "save" and press enter.
- reboot and check your VT.

In case you don't know how to create bootable flash media, a very good guide you can find here.

At this point I must say that described above method has worked for one guy and hasn't for another. In the latter case he redid all the things again but after typing "save" and pressing enter he pressed ctrl+alt+del and then pressed F2 to go into BIOS Setup and on the Exit tab he pressed the Load Setup Defaults and then rebooted to Windows. After that he has finally got Intel VT activated.

Anyway I hope you understand now why I delayed publishing of this guide. I just wanted to find 100% working method.



Middleton,

I followed this guide on my brother's Y550 which is identical to mine and everything went smoothly and no need to go into BIOS Setup and Load Setup Defaults. Now the both of us have VT enabled. Thanks again!

There was another guy, except for you, who activated VT by loading setup defaults at the end of the procedure. Currently, I don't understand what is the reason for it.

It seems that I've found the source of your problems. I'm waiting for Everest screenshot from you to make sure.
