Is Intel's Virtualization Technology (VT) enabled in BIOS for the (US) A8JS?

post #1 of 11
Thread Starter 
I'd like to know if the BIOS for the (US) A8JS enables Intel's Virtualization Technology (VT) or includes an option to turn it on. (I'm hoping to purchase an A8JS with a T7200 processor.)

I've seen that some other notebook vendors specifically disable VT by turning it off in BIOS without an option to turn it back on.

Can other ASUS notebook owner's respond as well?

I'm interested in running Windows XP as a Xen client while running Linux on the A8JS notebook (or alternatively, I'll run Windows XP as a VMWare client while running Linux on the A8JS notebook). I've also considered the same using QEMU but I need USB support and QEMU has just started to include USB support.

Thanks.

I think its automatically enabled no matter what unless you have a T2300E or equivalent meron model of the T2300E which do not have the virtualization technology.

Many buyers have made the same assumption to later find that the machine they've bought does not support Intel virtualization technology (VT). Some vendors (for example, HP) have specifically disabled Intel VT support in BIOS without an option to turn it on -- despite the fact that both the processor and chipset support vitualization technology. Buying hardware that supports Windows XP over Xen has been a hit-or-miss experience for many as there is very little documentation and little knowledge among pre-sales personnel from Intel as well as from vendors. Intel states that the chipset and the processor and the BIOS and the software must all support VT to have a VT system however finding the specifics for each piece of the puzzle and the specifics from a particular vendor... well, that information is not often published or known by those you can get on the phone or through email. The information is sparse within the user community as well. Without user confirmation on a particular piece of hardware, you just don't know for sure. Thus, I am still looking for confirmation that indeed, Intel VT is enabled in BIOS (or able to be disabled/enabled through BIOS) on ASUS notebooks. If someone can confirm that there is an option to turn off/on virtualization technology (VT / VMX extensions) through your ASUS notebook BIOS (and state which notebook you have), I'd feel more secure that the feature is present and enabled. Thanks again.

No option on mine.

Hello, I have a European Asus A8Js since last saturday. It's a great laptop!!
(see below)

+ some more info (to translate from French with google) and prinscreens on
http://forum.hardware.fr/hardwarefr/...et-33147-3.htm

No VT reference in the BIOS whatsoever (very simple Bios/not much details accessible)

Would you have a small program that I could download on it in order to check if VT is active or not ?
(unfortunately it is also not indicated on the CPU-Z summary with SSE3, EM64T, etc... technologies)
Or is it indicated on a winXP screen somewhere (System/Hardware config.) ?
See you. J.

Ok it looks good:

I assume the VT is enabled by default in the BIOS then.

No, I don't believe this verifies that VT functionality in the BIOS is enabled.

First, VMWare does not require VT functionality itself, though if available VT functionality will speed up a guest running under VMWare.

Second, from the documentation for the 64-Bit Compatibility Utility:

VT functionality can be disabled via the BIOS, but the processor check utility cannot
read the appropriate model-specific register (MSR) to detect that the VT functionality has been
disabled in the BIOS.

Ok. But then in case the VT is disabled in the BIOS : the check would not give a "Pass" status ?
(that's how I understand it : if VTdisabled, then the test would fail and would be unable to check if the functionality could even be activated via the Bios because the program is "blind" as regards Bios issues ?)

At your disposal for further testing if possible. (without installing entirely a Xen client on XP? except if it's easy and can be reversed? )

You probably are going to need to go to someplace like;

for the answer you are looking for. Or communicate your request directly to Asus engineering. Good Luck..
