Step 1: Rewrite the BIOS to meet the OEM information requirements. Vista will determine whether it passes the SLP verification based on whether the BIOS contains the OEMID string and the OEMTableID string. If the SLP verification fails, product activation will be required. The ACPI SLIC table information is 374 bytes, with the first 36 bytes being the table header and the remaining 338 bytes containing the OEM version information that requires authentication. As long as the BIOS contains the SLIC table and the RSDT table and they are correctly modified, the BIOS can generally be considered successfully modified at this point.
- Modify the main BIOS module
- Modify the ACPI table
