after a quick search :
SLIC (Software Licensing Description Table) is used by OEM versions of Windows for activation by Royalty OEMs in order for the end-user to not have problems with activating, called SLP, or System-Locked Preinstallation. For activation to work, clients obtained through the OEM channels that have an ACPI_SLIC table in the system BIOS are required to have a valid Windows marker in the same ACPI_SLIC table. The appearance of the Windows marker is important for volume license customers who are planning to use Windows volume-licensed media to re-image or upgrade OEM through the re-imaging rights provided in their volume license agreement. Not having the appropriate BIOS marker results in errors on these systems and prevents them from activating.
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.
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.
