Tutorial:Enable VT on InsydeH20 BIOS EFI way for VAIO or any supported notebook.Credits goes to: Bernhard Froemel
As we all know, current Intel Core 2 Duo on mobile notebook do support Virtualization Technology (VT) but unfortunately it has been disabled by Sony in BIOS. VT is useful for running virtual machine and also its let the user to use Windows XP Mode for coming Windows 7.
I got the method from
Enable VT for InsydeH20 based VAIO, the EFI way.
Just a reminder, the method is critical as for any mistake may brick the BIOS. So follow the guideline properly. I will just summarize the method and share with you guys the way I'm doing on my VAIO Z.
Anyway, lets started.
1. First of all ensure that you are using latest BIOS available from Sony website. In my case, Ive to get the BIOS updated, so Ive updated to latest version namely R2168M3.
2. Download the EFI file from the link above or here:
http://luna.vmars.tuwien.ac.at/%7Efroemel/...efi/BOOTX64.EFI and place the files in formatted FAT32 USB Thumbdrive inside BOOT folder which is inside the EFI folder. Create the folder first if you haven't done yet The file path should have looks like this: \EFI\BOOT\BOOTX64.EFI
3. Go into your BIOS (pressing F2). Make External Drive as first priority in boot priority, and save setting in BIOS.
4. Plug in USB drive, restart. There will be menu stating below:
> Welcome to GRUB!
>
> Entering rescue mode...
> error: file not found
> grub rescue>
5. After that, type: setup_var
Press enter, and you will see the license text and the warning etc. See at the bottom line, and ensure the GUID match the expected GUID.
6. Then type: setup_var 0x25a , (notes: value 0x25a enable advance menu in BIOS which let you access the VT option.)
Check if its at 0x00 (Default), if its not at this value, do not continue.
7. Next, type: setup_var 0x25a 0x1
8. Verify the value of 0x25a, it should read as 0x01
9. ctrl + alt + del, remove the USB drive after that.
10. Access BIOS by pressing F2. Go to advanced option and select Enable for Intel VT option. Save and exit BIOS.
11. Done.
Worked BIOS version so far:
1. R2168M3
2. R3052M3
3. R3054M3
3. R4040M3
