Important information.

I and szatkoff have solved the problem with his laptop. The old BIOS version (15CN21WW(V1.04)) was the cause of his troubles. To enable VT in that BIOS you have to change (0372) and (0375) BIOS variables instead of (0378) and (037B) in version 15CN30WW (V2.03).

I've already corrected my guide on page 4 taking into account this information.

Hi middleton.

I have a question about BIOS update in Y550.

A have BIOS 1.04 and a need never BIOS with option that i can disable "beep" when i plug in power. I now that BIOS in version 1.06 and later have this option. I think that you have some experience in BIOS for Y550 so i wanted ask you can i flash BIOS from 1.04 to 2.03 dumped from another Y550 laptop, without any problem? I think there are no big diference between this two versions of BIOS so this operation can be possible.

Sorry for my english.

Middleton- Thanks for all your help and hard work, it is a great service you are providing for the Lenovo Y series community!

Lenovo, Thanks for nothing!

BIOS Version 2.03 has essential differences from v.1.04.

You can't simply flash the newer BIOS which another Lenovo user backed up because such BIOS dump keeps all settings which specific for machine from where it was dumped. A newer BIOS from another machine will at best destroy unique data (serial number, all the setup settings) and at worst break your laptop.

If you despite of everything wish to try then I have to warn you: DO IT AT YOUR OWN RISK and only if you know BIOS recovery procedure for Y550 or have a good service center near to you.

Hello,

I must say that procedure you described, doesn't work for me. I have Lenovo Y550 with P8600 processor and BIOS v. 1.04. When I run dump.bat, there is no (0372) variable, so I add it and modify (0375).
Regardless of whether I use Load BIOS Defaults trick or not, it doesn't work. After I run Vmware Workstation it says that processor is capable, but VT is disabled in BIOS.

Best regards and thanks for your great work.

EDIT: As to "EDX (63-32)" and "EAX (31-0)" values, they are 0 and 9 for both CPUs.

Don't give up, szatkoff did a few attempts to get VT enabled. But if it doesn't work, you can send me your BIOS (see procedure in this topic) and I will try to modify it so that VT will always be enabled.

Also see previous post where Lenovo Y550 owner has successfully upgraded his BIOS from v1.04 to 2.03. If you want to risk then you can flash v2.03 BIOS and activate VT with my method.

Dear Middleton;

Thanks for this super thread. I was looking a solution for the Y550 VT problem ever since I bought my Lenovo.Though I had tested with Securable ( http://www.grc.com/securable.htm ) it failed to assure the VT

I have been told that I should have tested with Vmware Vt.iso ( http://communities.vmware.com/docs/DOC-8978 ) to fully assure that VT-x is Enabled and Locked at Boot. Have you tested the procedure against this note (where there is an VT.iso file attached to boot the system after the correction).

Let me come my specifics:

Lenovo Y550 w/ P8600 @ 2.40 GHz

BIOS Version 15CN21WW (v1.04)

EC     Version 15EC27WW(V.1.04)

with Phoenix TrustedCore

I run the CrystallCPUID 4.15.5.452 as stated in the blog  earlier and noted that the P8600 supports Intel64 and VT

Run it as administrator, go to "Function" menu and choose "MSR Editor". in edit control "MSR Number" type the value 0x0000003a. Then press "RDMSR" button and got the following output

CPU 1/2
EDX (63-32)                  EAX (31-0)
0x00000000                  0x00000009

CPU 2/2
EDX (63-32)                  EAX (31-0)
0x00000000                  0x00000009

I understand that I am potentially very close to get the VT enabled nd Locked whence I applied your procedure except that I should not edit BIOS variables (0378) and (037B) In my case variables are the following: (0372) and (0375). as I had the old BIOS type 15CN21WW(V1.04).

as  regard to how to create bootable flash media guide given under your procedure :

-need to download win98boot.zip

-need to download SP27608.exe

-and run this HP USB Disk storage tool as administrator

-need to download the VT-Lenovo_Y550.zip (instead of VT on a MSI GX-600 given in that guide)

-the official Phoenix utility symcmos.exe comes with the above file VT-Lenovo_Y550.zip indicated in yours procedure

Some questions:

Whence I run the Securable , I observe that Lenovo have not locked virtualization technology on Y550. Eventhough the P8600 supports it (this was also the message when I try to run 64-bit guest under vmware where it states the VT must be set at BIOS during boot).

Is there a way to test my machine before applying your procedure ;as you have suggested one of the forum participants questions (to eeKyy with Y530 w/9500) setting the MSR editors to the values EDX = 0x00000000, EAX = 0x00000005 and press "WRMSR" button ( I had tried this on my Lenovo but no change on the VT support observed ,is that because of the BIOS version in Y530) or should I apply different values for the EDX/ EAX registers..

Appreciate some answer before I go and apply yours procedure. And many thanks for the workaround hope that it works for me as well

Regards

M-Z - It took me a number of tries to get it working. The last try, which resulted in it working was powering off the laptop after running "save" as per middleton's instructions. Download the "havdetectiontool.exe" program from MS and you can use that to quickly check if VT has been enabled.

This is middleton's explanation regarding the (0372) register:

(0372) is a hidden register. It can be modified but you'll never see its value with symcmos.exe. (0372) value indicates whether CPU is VT capable or not. By default (0372) has zero value. If your CPU doesn't support VT then BIOS sets value to zero. But if your processor supports VT, BIOS will never set this register to 1. It's a bug in Lenovo BIOS.
