Couldn't find an authoritative link for this one, so just copied and pasted what I found posted on several Google hits I found on this subject.A lot of people were looking for N1996 board drivers, thinking that N1996 is the model number for their MSI products, such as MSI motherboards, optical drives, VGA cards and etc.
Well, that is not the model number.
It signifies that the product may be legally sold in Australia. Now it requires EMC compliance must be marked with the C-tick logo and ACA supplier code number. Our ACA supplier code is N1996. The supplier is responsible for holding a Compliance Folder that contains compliant test reports and a Declaration of Conformity.
This is more about ACA supplier code. According to ACMA (Australian Communications and Media Authority), Supplier Code Number means the number issued to a person by ACA or ACMA upon application for registration to use the compliance marks (A-Tick or C-Tick).
So basically, ALL MSI mainboards will have this N1996 identifying mark on, signifying that the product can be legally sold in Australia. N1996 is NOT your mainboard model.
To identify your mainboard correctly, see this FAQ:http://forum-en.msi.com/index.php?topic=113146.0
