How to Check or Verify PC Motherboard BIOS SLIC Version is SLP OA 2.0 or 2.1 for OEM Activation
System-Locked Pre-installation (SLP) is the mechanism used by big royalty OEM computer manufacturers to factory activate pre-installed Windows operating system on branded desktop PC, laptop, notebook, netbook and nettop computer so that activation process of Windows is done transparently and automatically once end-user first starts the computer. The offline OEM-style pre-activation that bypass Windows Product Activatin (WPA) is implemented to reduce the chance of annoying mass PC buyers from having to deal with activation after buying the computer.
There are now three different version of SLP, namely SLP 1.0 for Windows XP and Windows Server 2008, SLP 2.0 for Windows Vista and Windows Server 2008, and SLP 2.1, which supports Windows 7, Windows Server 2008 R2, and has backward-compatibility support for Windows Vista and Windows Server 2008 too.
For OEM activation to work and able to authenticate OEM licensing for Windows, three (3) components or criteria must exist and fulfill:
- Full SLIC table in BIOS
- OEM certificate (xrm-ms) which corresponds with OEMID and OEMTableID (Windows Marker) in SLIC table.
- OEM-SLP product key
SLP OEM Activation 2.1 works in very much the similar way of OEM Activation (OA) 2.0, with no change to activation technology, and OEM does not require to change factory process to accommodate new SLP 2.1 OEM activation. The only changes is Windows Marker version is now version 2.1 instead of 2.0. Even the digital certificate, which has file extension of .xrm-ms, signed by Microsoft with OEM’s SLIC public key (0×9C bytes) with Microsoft’s private key together with OEMID of SLIC table, is unchanged.
The second part of SLIC table, Windows Marker (0xB6 bytes) is created and signed by OEM with OEMTableID and OEMID together with OEM private key that matches OEM’s SLIC public key. OATools released by Microsoft will now write a new version 2.1 of OEMTables, hence a new Windows Market in different binary format for Windows 7 and Windows Server 2008 R2 OEM activation. Windows Vista and Windows Server 2008 accept both Windows Marker formats (OA version 2.0 and OA version 2.1), but not vice versa.
Thus, aside from new OEM-SLP product key (leaked Windows 7 Ultimate OEM-SLP product key) which is required for each edition of Windows 7 and Windows Server 2008 R2 in order to complete the OEM activation process, whether or not the SLIC 2.1 exists in the BIOS will determine whether the installed Windows 7 or Windows Server 2008 R2 can achieve instant offline activation on system boot up.
How to Determine, Check and Verify Whether SLIC in BIOS is OA 2.1 Capable for OEM Activation
Download and install RW-Everything Read & Write Utility. Run RW-Everything, then click on Access pull down menu, follow by ACPI Tables. In the opened ACPI Table window, click on SLIC tab. The display will look something like the illustration below, or see SLIC 2.0 and 2.1 example here.
A ACPI Tables Dump with SLIC 2.0
A BIOS SLIC Table Dump of OA 2.1
If the 4 bytes in highlighted area are 00 00 00 00, the SLIC is version 2.0
If the 4 bytes in highlighted area are 01 00 02 00, the SLIC is version 2.1.
If you’re having SLIC 2.0 in BIOS, try to wait for computer manufacturer if it will release new BIOS update that includes SLIC 2.1 table. Else, it’s possible to modify the BIOS (hardmod or biosmod) to include the SLIC 2.1 (assistance available at Windows 7 forum), or uses a OEM-BIOS emulator which commonly known as Windows 7 Loader, which in turn made use by various activators and toolkit to emulate a SLIC 2.1 on boot up.

I’m using Windows Vista on my HP Pavilion with W00tageman’s crack. I ran the RW-Everything app and opened the ACPI Table page. From what’s instructed above, mine seems like a SLIC 2.0, BUT THEN on the right column – i find the names Asus and Notebook.
So i guess, this tool is just reading off the simulated ACPI table – from W00tageman’s Crack – and NOT my HP SLIC table.

Hi Guys,
I used Vista activation with no pb, I have SLP OA 2.0.
But I tested several recent Win7 Loader without success, for information I upgraded my French Vista with a French Win7.
Any ideas?

To find datas : you can use Hedit 3.
Just open the bios in it, Ctrl + F, type “SLI” or “WINDOWS” then you should find info according to the pics above.
