    I have an HP g72-262nr that I am trying to install a 64bit operating system in a virtual machine. I looked up the specs for my processor, an Intel i3-350M and as far as I could see it does support VT-x but there is no where to enable this in the BIOS. The BIOS is an Insyde bios, i just udated to F.32 hoping that would do something. Is there any way that I can run a 64 bit OS in a VM on this laptop?

    Specs:
    HP G72-262nr
    Insyde Bios ID 1482 Version F.32

    Thanks, atreyu. I tried to use the EFI application and my laptop will not boot from the USB drive. When I attempt to boot from the USB drive the computer shows a message that says "Remove disks or other media. Press any key to restart." Is it possible to burn the EFI application to a CD and boot the application that way? I'm really quite frustrated that the option to enable hardware virtualization isn't available in the BIOS. Had I known that it was disabled I wouldn't have purchased this model.

    I'm pretty new to messing with BIOSes, how would I determine if it is the BIOS old style of UEFI?

    I did a little bit of research and apparently the BIOS is UEFI. In the downloads section on HP's website there is an option for "HP System Diagnostics (UEFI)" so I'm guessing that it is a UEFI BIOS. Unfortunately, the more I read, the more confused I get. A lot of the solutions are related to other platforms other than HP laptops.

    I have to say I'm definitely going to do more research before I buy another laptop. I read that the i3-350m supported VT-x and just assumed that I would be able use it as I needed to. I'll never make that assumption again. I downloaded the bios update from HP, it's just an executable named "SP51125" I noticed that I could extract the .exe file, and while there isn't a "platform.ini" file, there is a file named "1484.ini" that has the [BackupROM] section. I set the "Flag=1", saved the file, then tried to run "InsydeFlashx64.exe" and recieve a message that says "This BIOS is not for your Notebook PC" This is proving to be quite a pain. I'm going to read that thread again and try to figure it out. If being able to run a 64bit guest OS in a VM wasn't so important right now I would give up. :mad:

    Do I need to download the EDK II package? Or should I just follow MaxL's comment using the WinFlash tool? :confused:

    You don't need EDK II package. You need WinFlash or InsydeFlash, I would use the later bc it's from your bios mf. Didn't you use it to update to F.32? I've checked the package and there is a CheckCM.vbe that copies the right .ini to platform.ini, then there is no error... anyway there is no harm if you install the sp, perhaps the install procedure runs the vbe and that's why you had no error the first time.

    If you didn't install F.32 that's the first thing to do...

    Ok, I was able to get a copy of my bios using InsydeFlash. Now to patch it, I'll let you know how it goes....
    If the Patch Offset is wrong will that brick my laptop?

    Now when I run vtenable.py I get "Invalid VSS signature" I feel I'm getting closer.....

    As you have noticed if the offset is wrong you get a invalid signature message.

    Search for $VSS with an hex editor, and use first occurrence as VSS_OFFSET. I expect you get an output now, but don't use it. PATCH_OFFSET must be checked / changed, too.

    Here you need the so talked about main.py and lzma.py, maybe others. If you can't run it in nix you have to google for liblzmadec.dll and change main.py... well, you have to change it anyway bc the string you have (if you have one) may be diff from the hardcoded one...

    I can't assist you before the end of the day (gmt), good luck and enjoy the more you can

    I've been busy all day today so and my next oppourtunity to attack this won't be until after about 11pm GMT. I'm using dz6's main.py and lzma.py. I'll have to google for the liblzmadec.dll as I have been receiving the error that it couldn't find liblzmadec.so, I even tried installing Ubuntu 10.10 in a VM and had issues with that as well so I gave up late last night. Thanks for your help, it's been great.

    Ok, I finally found time to try doing this again. I managed to get this far:

    C:\Python26>python.exe main.py Backup.fd

    raise RuntimeError("Undefined opcode: 0x%x" % self.opcode)
    RuntimeError: Undefined opcode: 0x27

    Any idea why this might be happening? I am running Windows 7 64bit, I was going to install Windows XP 32-bit in a VM then try repeating this process to see if that changes anything.

    Update:
    I ran main.py and got the same error message.

    So, I changed "Vanderpool" to "Virtualization" and this is the output:

    Opened BIOS 'Backup_new.fd' with md5:D9e4fd92a9d0edcd4ccd628d6673918a
    Operating on BIOS data/original_bios-mine.fd size = 0x100000

    .. found 1 compressed sections

    Sorry, I couldn't locate the VT flag? :(
    Have vss_volume: <FirmVol position=0x0d0000 size=0x007fb8 where=None [VSS]>
    Have vss_volume: <FirmVol position=0x0f3000 size=0x00cfb8 where=None [VSS]>
    Have vss_volume: <FirmVol position=0x000010 size=0x2fffb8 where=[compr at 0x20069] [VSS]>
    Done

    So, I'm guessing this means that my processor doesn't support hardware virtualization but according to my laptop's documentation, it's an Intel Core i3-350M processor and according to Intel's documentation:

    Intel® Turbo Boost Technology No
    Intel® Hyper-Threading Technology Yes
    Intel® Virtualization Technology (VT-x) Yes
    Intel® Virtualization Technology for Directed I/O (VT-d) No <------- Does this mean that I've wasted our time?
    Intel® Trusted Execution Technology No
    AES New Instructions No
    Intel® 64 Yes
    Idle States Yes
    Enhanced Intel SpeedStep® Technology Yes
    Thermal Monitoring Technologies Yes
    Intel® Fast Memory Access Yes
    Intel® Flex Memory Access Yes
    Execute Disable Bit Yes

    I opened the "SetupUtility-mine.pe" in wordpad and did find a section that said "Virtualization Technology Hardware VT enables a processor feature for running multiple simultaneous Virtual Machines allowing specialized software applications to run in full isolation of eachother. HP recommends that this feature remain disabled unless specialized applications are being used."

    Hardware virtualization is 'Intel® Virtualization Technology (VT-x)', 'Intel® Virtualization Technology for Directed I/O (VT-d)' is a new expansion to this technology but not required.

    Thanks for the clarification FreeStyler. I'm guessing I have to change the search string in main.py. I'll try a few different things to see what I can find.

    Damn, python looks in help string and Virtualization is in the name; sorry :eek:

    Use "Hardware VT" or, better, shift the print

    Ok, now I get to the point where I run vtenable.py and I get the following:

    Traceback (most recent call last):
    File "vtenable.py", line 95, in <module>
    var = VAR(vss[off:])
    File "vtenable.py", line 58, in __init__

    ValueError: Checksum error

    Well, I was finally able to run vtenable.py, flashed the bios with the result, and nothing. Here's the result of running main.py, my "setup.txt" file, and what I used for "vtenable.py"

    This affair is been a nightmare, stupid HP!

    Your PATCH_OFFSET = 0x1ad is OK, what could go wrong? I would do this:

    - compare input and output of vtenable.py; there should be 2/3 bytes diff, the last should be a change from 0 to 1
    - get another bios backup to check if changes were commited; here the binary diff can be greater, the check can be done with mercan's python scripts.

    I can double check it if you want, just upload the 3 files (1st backup, vtenable out, 2nd backup) somewhere
