Hi, I have exactly the same problem and Sony model. Have you made some progress??

Regards.

Hey guys i have R0230Q0 Version of BIOS and my Laptop model is Vaio VGN CR 13G. Here is the link to BIOS...

http://www.sony-asia.com/support/download/241693?site=hp_en_AP_i&direct=true

I would appreciate it if you can help me identify which register i have to set it to 1

i am attaching the list of registers also that i got using symcmos utility..

List:

Thanks everyone for the hints !

I own a Sony Vaio VGN-FE31M  using BIOS R0200J3  which can be used from the FE41M or FE41Z.  Register  0195  set to 0001  worked for me !!!

Anyway : Stupid Sony Management. Their Vaios rock, but first the issue with the "Sony-brand-only-batteries" and now "vanderpool" disabled ... What for ?

They even tell you, that your CPU and RAM are limited with regard to upgrading.

I have 4 GB RAM now  though Sony say "only 2 GB possible"  and  I have changed my CPU from Core2 Duo T5600 to T7600 without Problems ...

We pay, we play !  Very cool, that people try to circumvent Sony's restrictions !  Ha, no way that I return my Vaio 

VT  here I come  !  ;-D

I just wanted to add my two cents worth along with a big thank you. I have a VGN-AR730E/B and have been desperate to get hardware virtualization working. Just wish I had of found this earlier.

In any case, register x0285 is the magic one for the AR730E/B with BIOS R2080JB.

Now I'm wondering if the same technique would work for my HP DL145 server? Maybe I'll give it a try later.

I have a Vaio VGN-NR11Z with R0131J9 BIOS. Any guess for the register to activate VT?

Thanks.

Hi

I have a sony vgn-sz28gp bios R0083N0.exe from sony.  I updated the bios and now my laptop is dead and could not boot up.  I tried flashing the with phlash16, PH1648 but all result in Platform Sigature Not found in the interface.

I could not load into window to flash with winflash.  Please help.

I saw this post on Slashdot today and thought of you guys:

No Windows 7 XP Mode For Sony Vaio Z Owners -

http://hardware.slashdot.org/story/09/08/11/1315255/No-Windows-7-XP-Mode-For-Sony-Vaio-Z-Owners

I should say that Sony has blocked virtualization support in all BIOSes. In future company probably will unlock it, but it`s for sure woundn`t be a Z series.

A big thanks to Bernhard.  This process worked fine for me on a Vaio VGN-SZ2VP with the latest bios.

Hi!

VGN-AR31MR with R200J6 Bios - Reg 0195

Works fine just from the first attempt.

Thanx all.

Scissor - thats exactly what I was needing when I came across this (and other linked threads on other sites). The information included by everyone does allow you to enable XP Mode on those VAIO desktops/laptops which support VT but it was helpfully turned off by Sony. Annoying for often such expensive equipment. Really Sony you should be producing 64 bits drivers and show all BIOS options rather than make us work so hard to get what we rightfully should already have. :o( Exciting journey tho - and lots to learn so its not all bad I guess!

I liked this thread as it gave details on the VGN-AR21S. To clarify for the person after asking how to enable VT on a VGN-AR21S you need to do this before starting the SYMCMOS stuff:

1) Download, and run the VGN-AR31S BIOS update from ftp://ftp.vaio-link.com/pub/DOWNLOADS/PH/B/SYS/PHBSYS-01175117-UN.EXE to flash your VGN-AR21S to a R0200J6 BIOS

2) Turn off (so not sleep, restart, hibernate, standy..) your laptop. Turn it on, and press F2 to enter the BIOS. Check it says your version is R0200J6.

3) Start the SYMCMOS process for the R0200J6 BIOS revision.... Do it all in DOS, and remember after changing it. Turn OFF your laptop (so not sleep, restart, hibernate, standy..) to ensure the change takes place.

There are a couple of threads around on the web about VT support for Vaios and this is a little behind some. I thought I would tidy up some of the posts from here, over at http://forum.notebookreview.com/showthread.php?t=189228&page=23 (post #227), http://www.wimsbios.com/phpBB2/topic9326-15.html , and comments on http://blog.steelooper.com/2009/07/enabling-virtualization-on-sony-vaio.html . None of this is my own work - I've only collected it into one place on this site. Many people have posted on both this site and notebookreview. Special thanks to scuderiaconchiglia & bfroemel without who I don't think we'd know the answer Thanks to everyone before me who made my life simple - and I hope this little bit of collection work makes up for my freeride.

WARNING - All this is at your own risk. You mess your computer up - you fix it. This is just helpful I hope. Many people have put this information in so some maybe wrong! Don't blame me for nuffin guv!

Here is a collected list of requests, and answers....

I thought it would also be interesting to split it differently. By BIOS Revision sorted by BIOS Rev on left and Register on right:

The starred ones in each list are ones I've found through google but on foreign pages so they need checking. Sources:

1* http://pc11.2ch.net/test/read.cgi/notepc/1202743621/l50

3* http://bbs.drvsky.com/read.php?tid=5961&uid=18620

This is a list of all the registers on all BIOS revisions so far that have enabled VT on Phoenix Sony Vaio BIOS. If you are going to try and find your own, understand the risks, know where the CMOS battery is located, etc - then this may be of use:

I've also attached the information in CSV and Excel 2007 format incase people need it like that. Hope this helps someone find their answer.

We could make a much better list by working out (as I couldn't find any information freely available from Sony) of what laptops come with what BIOS revisions by default. Anyone know of one? You can painful get ones which have updates available but original BIOS information is hard to come by it seems.

Note: The process described in this thread only works for Phoenix BIOS, not AMI/etc.

Hope it helps someone!

Add to this list VGN-G11XRN/B (BIOS: R0062N5)

VT Feature working with 0363 register.

Sony VAIO VGN-CR123E (US)

BIOS revision R0231Q0

for enabling Intel-VT change 05B2 register from 0000 to 0001

Any suggestions for a VGN-NR160 ? I saw some posts elsewhere where Sony was slowly releasing BIOS updates. I'm debating giving it more time to see if a BIOS update appears or to attempt to turn it on myself...  Thanks,

David

If your BIOS revision is R0131J9 I would try 02D0.

But I can only guess.. Sorry.

If not, try all registers from the last table where BIOS revision ends with J#

Good luck!!!
