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
