Install the Modem Driver
Introduction
Compatibility: This MultiMobile MT9234MU MultiModem is compatible with Windows Operating
Systems Vista/XP/2003/2000 and Linux.
Windows Drivers: The MultiMobile MT9234MU driver must be installed in your computer’s program
directory. The Windows drivers are located on the MultiMobile MT9234MU CD in the Drivers I Windows
Drivers folder. A complete set of drivers for each operating system is organized into Vista and XP with
either 32-bit or 64-bit processor. Most users will select either the 32-bit Vista or 32-bit XP drivers
(Windows 2003 also use the XP drivers). Windows 2000 users must select the drivers from the Drivers I
Windows_2000 directory. Server users can select either 32-bit or 64-bit depending on their application.
For server users to determine whether they have a 32-bit or 64-bit operating system, go to Start I All
Programs I Accessories I System Tools I Computer and click on the System Properties button.
Under System you will see System Type: 64-bit Operating System.
When installing the 64-bit version of the Vista driver, a person will have to disable the “signed” driver
check in order to install it. Two methods are available, choose one:
•First Method
Boot your PC, press F8 and choose “Disable driver signature enforcement option”.
•Second Method
•Create a shortcut on the desktop to cmd.exe using the following steps:
•Right click on an empty space on the desktop to open the context menu
•Select New
•Select Shortcut with a left-click
•In the Location box type cmd /k
•Right-click on the shortcut and select Run as administrator
•When the command window opens, type or paste the following and press ENTER:
•Reboot your PC and install the driver
Linux Drivers: Linux Operating System drivers are also located on the CD in the Drivers I Linux
Folder. Refer to the Readme file (also in the Linux directory) for the correct driver file and installation
guide for your distribution/version of Linux.
Overview of Windows Driver Installation: Three install wizards guide you through the software
Installation in this order:
Part A installs the USB Driver.
Part B associates the PC port with the USB Driver, and finally
Part C installs the modem .inf file.
