Well, that is not the model number because it is not possible that alot of products sharing the same model number, right?

Then some one on forums mistakenly saying that N1996 is MSI FCC identifier printed on all MSI boards/optical drives/VGA cards, which is NOT TRUE as well. To know what N1996 means to your MSI products, see below for the proof:

According to MSI official website, A C-Tick mark (see above) may also appear on our MSI products that are required to comply with Australian electromagnetic compatibility requirements and radio-communications standards.

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 now you know what N1996 means for MSI products. To find the MSI drivers, you need to find out the correct MSI model numbers, for example here are few of the correct MSI model numbers/codes, hope you can see the pattern here:

1. K9N4 Ultra-F
2. K8M890M2-V
3. G965M-FIR
4. NX7600GS-TD256
5. S300-008US
6. MP54GBT3

Alternatively, I would suggest you to try a driver scanning service which will identify your hardware information and then locate the most recent driver for it. One of the more accurate is Free Driver Scan. It will save you countless hour and headache and best of all, get the working driver fast.
