Installation for Windows 98SE and Windows 2000 

Before installing the driver, you will need a copy of the operating system installation media, 
usually a CD supplied with your computer or operating system. 
 
On Windows 98 systems, the installation files are sometimes archived on the hard disk in 
C:\WINDOWS\OPTIONS\CABS. On Windows 2000 systems, the system may prompt you 
to load operating system files from the Windows 2000 installation disk. Installation under 
Windows 95 is identical to the procedure given above for Windows 98 and Windows 2000. 
 
The Setup program also installs Configuration Utility in the DW-125 Wireless LAN USB 
Adapter in the Program directory. This configuration utility can help you to understand and 
maintain your Wireless LAN.
