4. Installing the Mini PCIe Card
1.
Remove the Mini PCIe card from its protective antistatic
packaging, remove the screw holding the Mini PCIe card to the
motherboard and insert the new Mini PCIe card into the socket.

5. Software Installation
To install the Windows drivers, there are two methods, one is to run the
setup utility (StnSetup.exe) in each corresponding folder. The other one
is by the Windows’ driver installation Wizard. We recommend you run
the setup utility. It will be simpler. However, PLEASE REFRESH HARDWARE
OR REBOOT THE SYSTEM IN CASE YOUR DRIVER DID NOT TAKE EFFECT
AFTER RUNNING THE SETUP UTILITY.
The drivers are shipped in the following folders on the driver CD:
E:\IO\MOSCHIP\MCS99xx
Drivers are in each
corresponding folder

6. Uninstalling the Software Drivers
In some cases, you may want to uninstall the drivers. To remove the
drivers that already installed for Windows, there are two methods:
1.
Run (double click) the uninstall program (for example
MOSCHIP_StnUninst.exe) in each Windows’ folder on the
supplied driver CD, it is usually in the same folder as the
StnSetup.exe utility:
2.
Go to Windows’ Control Panel’s Add/Remove Program to
remove the drivers.
