Getting tired or scared of modifying motherboard or computer BIOS to get instant Windows Vista activation ala OEM edition preinstalled in branded machine? Now you have a very easy way to achieve OEM activation for Windows Vista, without the need to modify, download, patch, hack, crack or flash the BIOS of motherboard, and of course, without the risk of burning or spoiling your motherboard or causing your system to fail. The working theory of this new Windows Vista OEM activation crack method is that when computer is started, the crack will be launched. The crack will then simulate the result of actual mod of BIOS by opening a command prompt, then adding SLIC table data of ACPI into BIOS before loading BIOS virtually into memory, and finally loading the Windows Vista operating system.

To use the crack is extremely easy. The crack is actually vstaldr driver, which is actually a boot manager which is called every bootup to bootstrap Windows Vista. The drive reads the SLIC.BIN file contained inside the vstaldr.img to get the SLIC table data, and use it to simulate as BIOS to load the Windows Vista operating system. The success of Windows Vista OEM style instant activation relies on the success of simulation of the creation of BIOS with SLIC table with proper OEM ID. This crack will simulate the BIOS with OEM ID and OEM Table ID of _ASUS_Notebook, the commonly used OEMID for Windows Vista activation hacker. There are actually a few methods to use this crack, some is listed below, and just follow the simple steps and instructions:

Method 1: Bootable CD

  1. Install Windows Vista without product key, or with the following ASUS OEM product key:


  2. Download the ISO CD image file (sofmod-l.iso).
  3. Burn the ISO file to a CD with tool like Daemon Tools.
  4. Reboot computer.
  5. Boot up computer from CD-ROM or DVD-ROM drive.
  6. The vstaldr boot manager will hack the BIOS to simulate a mod BIOS which supports SLP 2.0 with SLIC table, and automatically load Windows Vista when complete.
  7. Download and install the appropriate OEM certificate (ASUS in this case), if your Windows Vista DVD media is not OEM edition.
  8. Change product key to Windows Vista OEM key if necessary.

Method 2: Direct Launch from Hard Disk

  1. Install Windows Vista without product key, or with the ASUS OEM product key.
  2. Download the ISO image (softmod-l.iso).
  3. Extract the content of the softmod-l.iso ISO archive with extraction tool like WinRAR. You can also use a virtual CD-ROM or virtual dvd-rom emulator such as Daemon Tools or disk imaging utility such as WinImage to load or open the ISO file.
  4. Open elevated command prompt with administrator privileges. Confirm any security warning that pops up.
  5. Execute the install.cmd from the extracted softmod-l.iso folder. You must execute install.cmd from within the folder where it’s located itself, so CD into the folder first. Installer will attend to copy and install vstaldr, vstaldr.img and menu.lst to all drives with Windows Vista installation, and modify the MBR (Master Boot Record) to load the BIOS crack driver as bootstrapping process to load simulated SLP 2.0 supported BIOS with SLIC table data. (If installation on certain drives fail, as long as it’s not the Windows Vista boot volume drive, the failure can be safely ignored.
  6. Restart the computer.
  7. Optional: If your computer fails to boot up or start, use Windows Vista installation DVD to boot up the computer, and choose Recovery to repair the computer.
  8. Download and install the appropriate OEM certificate (ASUS in this case), if your Windows Vista DVD media is not OEM edition.
  9. Change product key to Windows Vista OEM key if necessary.
  10. To uninstall vstaldr driver, simply click on uninstall.cmd from the extracted archive.

Note: You can initially boot up with the softmod-l.iso bootable CD (in method 1) to verify that the BIOS simulation actually works, and then only install the BIOS simulation crack as in method 2. You can also permanently and long term using boot up with the bootable CD.

Method 3: Bootable USB Flash Drive

  1. Install Windows Vista without product key, or with the ASUS OEM product key.
  2. Download the ISO CD image file (sofmod-l.iso).
  3. Create a bootable USB flash drive.
  4. Open \data\vstaldr.img with WinImage. Copy all the contents and files inside the archive to the root folder of USB flash drive.
  5. Edit te menu.lst to the same as below:

    timeout 30
    default 0

    title vista(boot from usb fdd)
    chainloader /bootmgr

    title xp(boot from usb hdd)
    map (hd0) (hd1)
    map (hd1) (hd0)
    rootnoverify (hd1,0)
    chainloader +1

    title vista(boot from usb hdd)
    root (hd1,0)
    chainloader /bootmgr

  6. Restart computer.
  7. Boot from USB flash drive, and select the appropriate menu item on the menu selectin to load Windows Vista. Bootable USB flash drive is more complicated, so 3 options are given for choice in case of failure.
  8. Download and install the appropriate OEM certificate (ASUS in this case), if your Windows Vista DVD media is not OEM edition.
  9. Change product key to Windows Vista OEM key if necessary.

Note: The BIOS simulation patch should works on dual-boot or multi-boot system or system with boot manager too to activate Windows Vista instantly and permanently. And, actually, sequence of steps is not exactly important, as long as all is done, instant activation will work.

Side effect: Some users reported that the A drive (floppy disk) is gone or inaccessible after using this BIOS simulation patch for Windows Vista activation. This is due to the fact that the patch works by hooking computer’s A: drive and attaching the floppy image ‘vstaldr.img’ to it. The temporary workaround is to use B: drive instead to access floppy drive if your BIOS (normally at Standard CMOS Feature) support the setting that you have two floppy drives – A: and B: – both as 1.4MB 3.5″ devices. Then go to the Advanced BIOS Features section, find the option for ‘Swap Floppy Drive’ and switch it’s current state – if it is currently enabled, set it to disabled, if it is currently disabled, set it to enabled. In addition, in the same Advanced BIOS section, find ‘Boot-up Floppy Seek’ and make certain it is set to disabled. Save and exit the BIOS. This workaround will allow the VSTALDR patch to hook the A: floppy drive as it must, but will take your real floppy drive and assign it as the B: floppy drive. From this point on, in Windows, you can access the real floppy drive as B:. While A drive in Windows Explorer can be hide with the common hide-drive registry tweak method. You won’t be able to boot from a real floppy disk with this workaround in active too, unless you do actual BIOS flashing and reverse the CMOS change.

See also Paradox OEM BIOS Emulation Toolkit, which can be used as alternative or workaround. softmod.iso software based OEM BIOS emulator for Dell, HP, Lenovo, Sony and etc is also avaiable.

The BIOS simulation patch to permanently Windows Vista as OEM edition is tested to work on many OEM brands of desktop and notebook computers such as Dell, Lenovo, IBM Thinkpad, Acer, Sony, Fujitsu, LG, Samsung and etc. Beside, it’s also possible to crack AMI, Phoenix and Award BIOS that previously unable to patch with SLIC table.

  • vista installer

    sorry ment to say NOW & not NOT in my earlier post below.

  • vista installer

    worked 100%

    no problems what so ever.

    i tried it on windows vista eternity 2009 sp1.

    this is how i done it:

    1.first download the sofmod.iso application.

    2.then usin nero or magic iso to burn file to dics.

    3.once disc has finished burning restart pc and boot from the cd.

    4.check in system properties and check if its activated.

    5 if it has activated then it work so inorder to keep activated without further use of the cd explore the cd so u can see the files that are on th cd then look for the install.cmd file. left click on it an run as administrator an that is it. your pc will not be activated upon bootup without the use off the cd.


    by the way thanks to the author of this page could have done it otherwise as most the cracks out there dont seem to work now a days.

    gonna try it on home basic sp1 next so will let u kno how it goes.

    Worked fine for me.

    I discovered that if you use option 1 (the bootable CD) – and presumably also option 3 (USB drive) – then it will only work when booted from the vstaldr bootable CD. If you want it to work permanently, you have to use the 2nd option – direct hard disk install.

    At least, that's what I found on MY system…

    Forget SLIC tables.

    Every time when youu switch on your machine on boot from CD and Vista is activated.

    see you later.

  • compass

    nimiq #36 & #39

    No luck. Vista ultimate loads OK using the vstaldr but the SLIC table does not appear in the ACPI section (using latest EVEREST).

    Did you have an empty SLIC table before you applied the patch ?

  • alanmies

    I did it like this:

    1) Burned the image on CD

    2) Rebooted from CD (Vista will start after a short period)

    3) Run

    slmgr.vbs -ilc C:oemcert.xrm-ms

    (before that I copied oemcert.xrm-ms from CD to C-drive root directory)

    4) Run

    slmgr.vbs -ipk 6F2D7-2PCG6-YQQTB-FWK9V-932CC

    (Tis key is for Vista Ultimate only)

    All worked like dream in two different machines.

    For novice user:

    Copy/paste the above commands 3) and 4) to avoid mistakes and check if oemcert.xrm-ms is really located in C-drive root diretory C:/

    After crack you can remove this file.

  • compass

    nimiq #36

    Ah! That's better. Thanks.

    I noticed that after cracks that both machines has the same Prodúct ID: 89580-OEM-7332132-00031

    How many officially genuine software with the same ID exists? What can M$ do? Can they blacklist all users who has this ID?

  • compass

    I have a MSI P965 Platinum motherboard which has an AMI BIOS without an SLIC table.

    I have completed all the steps exactly but it doesn't work.

    It definitely makes modifications to the BIOS but does not add the SLIC table, not detected by EVEREST.

    I still will need a patched BIOS.

  • nimiq

    Works perfectly on my A8N32-SLI Deluxe (and VMware machines)

    I don't know what you guys are doing wrong. This validates as genuine too.

  • Thien

    In Method 1, do i have to use this boot CD every time to start Vista or just once to activate?

  • bytee

    Is there any way to "detect" if BIOS/motherboard supports SLIC and is able to use this crack?

  • TWiST

    Bro just extract the iso and go launch install.cmd form a "Run As Administrator" command prompt, Or burn the iso like u would ANY iso, get Iso Recorder if u want the smallest simpliest solution, and boot from that disc and it will launch ur vista activated, but I would suggest teh first method and install to HD, then u dont need USB or CDROM or anything to deal with it.

  • baard

    strange guide :

    [quote]Burn the ISO file to a CD with tool like Daemon Tools.

    Reboot computer.

    Boot up computer from CD-ROM or DVD-ROM drive.


    1. Burn with daemontools?

    daemontools is no burn prog

    2. boot up from cd/dvdrom drive?

    And boot wich one? original vista or the sofmod-l.iso ?

  • TWiST

    This is a note for any1 that has had a bricked bios. If you have a computer with a similar bios it is possible to "hot swap" the bios to restore a bad flash etc. I have done this in the past MANY times and know it will work. Example;

    Lets say you have 2 motherboards, 1 is fried the other is fine, and they both happen to have hte same bios packaging (by packaging I mean the pin layout and size and shape, etc.). Go ahead and boot up the working system to a boot disc, winpe, whatever u like to do ur flashing in, and once its booted go ahead and remove the bios from teh computer while its running, I know this sounds scary but I assure u it will be fine. Then go ahead and put in the "bad" bios, making sure to line up the pins correctly (this can FRY the bios chip if u put it in wrong) and once its in go ahead and reflash it back to the correct bios. I understand this method is for the ghetto and poor, but it works and ive done it a BUNCH of times over the years, espicalley alot during the duel PIII and Celeron days, when I remmeber hacking the hell out of the BP6 er whatever it was by abit I believe (ahh the good old days).

  • amnesia


    Successfully activated on my ASUS M2V!

  • TWiST

    I have noticed something when using this method, if u run dxdiag.exe or generate a system report, it still returns the correct values from the bios ? So whats stopping microsot from just checking the real values instead of whats its being fed during boot to invalidate this process ? Like for example my Bios is a gigabyte so in teh BIOS of OEM it says GBT__ but for this it should be ASUS_ or whatever, so why inside windows does it know the correct values ? If any1 knows the deeper working of this and has any sort of info would be great! Cause right now its looking like MS is going to be able to see past this crack easier then I had first expected. When modding the actual bios, dxdiag and these programs return the hacked values like there suppost to but using this method we get the original values…

  • bjuj

    is this compatible for all desktp pc and notebooks?

  • admin

    Niko76, I echoes the comment by TWiST at #14 that your hard work will never been forgotten, and together with actual crack on BIOS, both serves different needs.

  • weedywhizz


    …same opinion as TWIST

    But still no ASUS P5B BIOS modified. Are there any special probs with that kind of mobo?

    For this board the only way to modify is via this software hack yet.

    Another thing….your Abit IB9 BIOS bricked my board – no boot up any more…ordered a BIOS-ROM from Abit…

  • TWiST

    Niko76 I still believe u should fight the good fight, cause a true bios hack is better then this because it dosent require any extra software that may for say 1 out of 1000 people possibly cause incompatability or the like, This is a fantastic method for people unable to edit there bios, but if u can edit ur bios I would strongly suggest u use that rather then this! Just my 2 cents.
