Sony SR - Enable VT

Hi anyone has verified if the Sony Sr comes with VT (Vanderpool Tecnologiy for Virtualization) enabled?

If not anybody has identified the register of the cmos configuration to set to 1 to enable it?

Thanks

 

Yes, mine has VT.

 

Excuse my ignorance, but why is VT useful? And how would I check if it's enabled on my new Z?

 

nigeljs:

What exact model do you have? i've ordered the VGN-SR19XN; in italy it's the one with the fingerprint reader and the tpm; in your model there are this features? (any other user knows if the vt it's enabled in all SR or not?​

InfyMcGirk:

The Vt it's an hardware technology to support virtualization, so yes it's useful for an increase of performance if you do virtualization; I think your model has it enabled beacause it's dedicate to high business use but i'm not sure of that.​

 

I have the VGN-SR192E (from newegg.com). It has a fingerprint reader and TPM, but I believe that all the SR's have that. I also think that all SR's have VT enabled.

You can see with the Intel Processor ID Utility.

 

the vt in the processor is disabled on the sr19xn

i've checked it with the vmware test cd: vt.iso [you find it with google]

somebody knows a way to enable it' ?
i know the cmos way but i dont know he register to modify!

 

excuse my nubness but what is "VT"?

 

Use the program Securable to see if VT is supported, not supported or locked off.

All Vaio notebooks have VT locked off except for the BZ series I hear which uses a different BIOS. I do not know why Sony does this but some other manufacturers purposely lock this feature off as well.

Not all processors support VT, the lower end processors lack it such as the Celerons.

VT is Intel's hardware virtualization which makes the process faster than if done in software. AMD has their own version as well.

Virtualization lets you run another operating system within your own, such as I can run XP in a window in Vista for programs that are not compatible in Vista.

When there is no hardware VT, the process is done in software and generally slower.

 

rahulrnirmal i surely think that it's disabled.

the program you suggest me retrive the cpu model id and wrtite down the possibilities of the cpu... but sony disable vt by the bios


can you try also with the vmware vt.iso imag? you find it with google searching "vt.iso"

any oher can try?

thanks a lot

 

The processors in these Vaio notebooks fully support Intel VT, but Sony locks it off and there is no option in the BIOS to enable/disable it like on some other notebooks.

I'm sure someone will find a way to enable it with a hack, its been done on other Vaios like the TZ, FZ and CR.

 

rahul is right. Currently the BZ is the only VAIO series that allows you to turn the VT option on, among other things. I was very happy that they have done so, allowing users much much more access on a BIOS level than ever before. It also means they've stepped away from Phoenix for the new BIOS, and I wonder why as Phoenix is fully capable of providing a more full featured BIOS that the BZ could have used I'm sure.

 

yes: there is also a confirm officila by sony that it's disabled also on sr: http://www.vaio-link.com/specifications/specifications.asp?site=voe_en_GB_cons&c=0&s=VGN-SR&m=3365
[you can read it on the bottom of the page]


so the solution is boot with a dos disk and change the cmos register.

has anyone tried it ?

 

i've tried using Freedos and executing "symcmos -V2 -LDefault.txt" but it don't generate the cmos configuration file as attended.

has anyone tried to do the same thing?
there is something strange with the sr, because others sony vaio laptop has no problem with the syscmos utility
