4.10.5 OEM Active 1.0/2.0/2.1 and KMS activation Support
OEM Activation 1.0 (a.k.a. SLP 1.0) is used to activate Windows XP. To support it,
BIOS needs to populate OEM string in the 0xF000 segment during POST.
OEM Activation 2.0 (a.k.a. SLP 2.0) is used to activate Windows Vista. To support
it, BIOS needs to populate ACPI SLIC table during POST.
For projects supports Windows 7, SLP 2.1 is required to support.
MS claims the Windows marker is MS’s IP and cannot appear on non-Windows
OS SKUs. An EEPROM flag OS_SKU (refer Sec. 9.4) is defined to indicate the
machine is shipped with Windows or non-Windows OS. The flag is programmed in
the factory and BIOS needs to read this flag when populating OEM string/ACPI
SLIC table. If the flag indicates the machine is shipped with non-Windows OS,
BIOS will not load Windows marker structure in ACPI SLIC table.
KMS Activation support.
To support the KMS activation, the SLIC table should be removed from the ACPI
table.
To support multi customer, BIOS should remove the SLIC table as default, and
populate the SLIC table if customer enter the OEM ID, OEM table ID and OS_SKU
in the EEPROM. The customer should create customized BIOS with SLP2.0/2.1
market and public key at the same time to active Vista/Window 7. Please refer to
the “How to update OEM SLP” for the detail instruction of customized BIOS
creation.
4.10.6 Multi Customer Logo Support
To support Multi customer Logo, BIOS will merge dummy OEM logo in BIOS as
default, and customer should create customized BIOS with OEM Logo. Please
refer to the “How to update OEM Logo” for the detail instruction of customized
BIOS creation.
