If you intend to modify your BIOS physically and hard code the SLIC table content and data into ACPI section so that it’s SLP 2.0 (System-Locked Preinstallation) supported and compliant to achieve install and permanent Windows Vista activation as OEM edition, you should know that you have to mod the BIOS SLIC and SDRT tables so that they have a valid and legit OEM ID and OEM Table ID, which match and validate correctly against respective Microsoft signed OEM digital certificates. Hacker community has currently the widely known ASUS OEM_ID and OEM_Table_ID. Here’s more OEMID and OEMTableID for various famous original equipment manufacturers (OEMs) which can be used to mod the BIOS to.

With these OEM ID, a BIOS can be modded to match other OEM instead of ASUS. However, you need to get the OEM’s ACPISLIC.BIN (or SLIC.BIN) which is extracted from genuine product to complete the BIOS crack to activate Windows Vista. If can be used to modify the no flashing BIOS emulator which requires no hard modification to physical BIOS to use other OEM ID too.

The OEMID and OEMTableID is retrieved and verified from the BIOS that supports SLP 2.0 and contains SLIC table, by using ACPISLIC.BIN or SLIC.BIN that can be separated from BIOS with tools like CBROM, and then view it in HEX editor.
