No Windows 7 XP Mode For Sony Vaio Z Owners 198

Voyager529 writes "While virtually every Core 2 Duo processor supports the hardware virtualization technology that powers the Windows 7 XP Mode, The Register UK reports that the Core 2 Duo processors in the Sony Vaio Z series laptops had the virtualization features intentionally crippled in the BIOS. Senior manager for product marketing Xavier Lauwaert stated that the QA engineers did this to make the systems more resilient against malicious code. He also stated that while they are considering enabling VT in some laptop models due to the backlash, the Z series are not among those being retrofitted."

      I actually reflashed my Vaio VGN-FW285J in order to enable Intel VT-x which was deliberately disabled by Sony. It irked me to no end that they disabled this feature, since I would not have bought the laptop if I'd known they'd disabled it. The procedure on how to reflash is on my blog, along with links on how to do it for Sony's other Vaio laptops (such as the "Z" series). The blog post is here: [] Credit should of course go to those fine folks who took the time to reverse engineer the BIOS, such as Igor Levicki who did this for the FW series' AMI BIOS.

      It matters because the way the VT tech works is that its disabled by default in the CPU, and is (usually) enabled by the BIOS. The reason you cant (usually) turn it on after the OS has booted is because the register used to turn it on (the MSR) has a lock-bit, which once set prevents any changes to the VT status until power is removed from the CPU.

      BIOS's that simply ignore the VT enable stuff are less of a problem, because its possible to set the VT tech on, and lock it on (by writing 5 to register 3A) within the OS using /dev/msr (linux) or cpuinfo (windows). The Mac Pro (early 2008) behaves like this. This is obviously bad for security, as the malware can simply enable it!

      BIOS's that deliberately disable VT will set the register to 1 (vt off, lock on), turning off, and locking off the VT stuff. There is no way I know of to defeat this situation (short of disassembling the BIOS and 'fixing' it).

      Some BIOS's even have the code to turn it on, but it is only triggered if a CMOS register is set to a certain value and there is no UI on these BIOS's to set that CMOS register. I believe some Sony BIOSs are like this, but am unsure.

      The best ones of course allow you to turn it on in the BIOS - which is why Sony are talking BS when they say its for security. They only need to ship it turned off, and allow the users to turn it on at their own risk.

      I understand that it IS a genuine risk (bluepill?) in that a hypervisor can install itself UNDER the OS layer, and then filter what the OS sees, invisible to the user (otherwise the virtualization is broken).

      Thats why.

      ps. apple ignored a bug report I made about the way the Mac Pro works... i guess its kinda understandable because it seems all MacOS virtualization products just turn it on using the MSR as needed.

    The virtual technology extensions of my Lenovo Thinkpass T400 has also been intentionally crippled. Sony isn't the only company making bad decisions with higher-end laptops.
    • Were they intentionally crippled, or just disabled by default? There's a big difference.

      • Crippled. One can't turn on the feature, seems to be an issue with the BIOS. If VT extensions worked on the Lenovo Thinkpad T400, why would Lenovo turn this feature off by default? They wouldn't, unless they had a technical reason (e.g issue) to do so.

    Back in 2000, when Win2K was out and happy but the proles were stuck with Win98/ME, I decided I wanted a laptop.

    There was a cheap Sony laptop with Win98/ME on it that looked good to me and was on sale. I checked, there was a version of the same laptop with Win2K available, but it was a few hundred dollars more if you could FIND it, and the UC CS dept had a site liscence/arrangement for Win2K.

    So I figured, why not? Buy it at fry's, reinstall with a remotely tolerable Windows OS, be happy.

    Get the laptop, blow away the Win98/ME crap, put on Win2K, only to find out that Sony locks all the drivers with BIOS strings and the like so the drivers from the Win2K version won't install on any other notebook, even when the chipsets and everything are identical!

    Fortunately, Fry's had a good return policy. So rather than going hunting for manufacturer sites for drivers, I said, screw it, popped in the reimage disk, and restored it and returned it.

    A few weeks later, I bought an IBM notebook off a friend with PowerBook envy, much prefering the IBM site wher you put in the model # on the bottom and you get every driver for every OS variant, including Linux, in a nice neat grid...

    But even nearly a decade ago, Sony was gimping their laptops badly. Glad to see they are keeping THAT tradition alive...

    The first line of this summary is quite wrong. Intel has LOTS of Core2Duo's that do not support Intel VT. A quick look through their processor matrix will confirm this. Still, it's common practise for laptop manufacturers to disable things like VT on their consumer models. My Toshiba satellite has it disabled (not changeable in BIOS), but the pro version of it (same mainboard and cpu) has the option. I'm sure there is some way to get it working via a hex editor or something, but then we're into voiding warranties (if the bios gets fubared).

While I like the fact that some of the new Pentium processors run really cool, I would never consider buying a new processor without virtualization support. Yet most of the current cheap machines (laptops and boxen) that come with Intel use processors without virtualization. Kinda limits your choices. But then again I always liked AMD better.
