Virtualisation is now disabled in the latest DV2 BIOS

[rgunther59]

I updated the BIOS in my Pavilion DV2 to the latest F27A version and now hardware assisted virtualisation for the cpu is disabled. There is no way of re-enabling this in BIOS. I need Virtualisation to run XP mode in Win7.

How can I restore my original BIOS or re-enable virtualisation with the current BIOS.

Hi,

You don't need anymore virtualisation to use XP Mode.

Check below link to get more informations about this change:

Windows Virtual PC and Windows XP Mode no longer require HAV processors

Edit:

If You want to have back Virtualization in Bios then downgrade Your Bios version to this which You had.

How You may find older Bios?

1. Click on Support & Drivers link. (Upper part of this page.)

2. Choose option: Download drivers and software (and firmware)

3. In form:

       Enter a product name / number

       For product provide Your p/n. (How to find correct p/n informations here.)

4. Click on Go and choose Your system.

5. Find on the list there Bios section and in the column titled ' Previous ' click on ' Versions ' link. This way You will see all Bios version which were released for Your specific model.

Please try VMlite software to run the X Mode image. It is faster and has more features than Microsoft's "Virtual PC" software.

It's free after free registration from www.vmlite.com

I use it and I cannot believe the vast difference in the two virtualization programs.

There is an easy way to activate the AMD-V switch in Bios again. I've found this solution here in the HP Forums and it worked fine on my German HP Pavilion DV2-1050eg. Credits to the original poster:

"ok i worked out how to do it myself, for anyone else who's interested in doing this first download a tool called symcmos.exe, boot to dos with a win98 floppy or a freedos prepared usb stick (it must be dos and not just a windows command prompt) with symcmos.exe on the same floppy/usbstick and when at the dos prompt run,

symcmos -V2 -Lcmos-output.txt

when that is finished reboot back into windows and then edit cmos-output.txt and find the line that shows

(017D) [0000]

and change it to show

(017D) [0001]
 
then save it as cmos-output1.txt on the floppy/usbstick

now reboot back into dos with the floppy/usbstick and run
 
symcmos -V2 -Ucmos-output1.txt

once that is complete boot back into windows and you will find that your hardware virtualisation is now enabled. why HP in their wisdom decided to disable parts of the processors capabilities is beyond me! but there is always a way round these things lol.

this instructions is for a HP DV2-1030ea with bios version F27.A, i may be able to help others with different laptops/bios versions so if you want your hardware virt turned on just post here "
