The purpose of this document is to provide users of FTDI chips with a simple procedure for
installing drivers for their devices under Windows 98. The procedure is also applicable to Windows
ME.
Please note that if Windows 98 Gold Edition is being used, you must have all the latest patches
from the Microsoft website installed for the system to be USB compatible.

2Installing FT232BM, FT245BM, FT8U232AM and
FT8U245AM Devices
FTDI's 1
st
and 2
nd
generation of USB UART and USB FIFO chips can be installed with one of two
sets of drivers.
The first driver type is the D2XX direct driver. This provides direct access to the device via a
dynamic link library (DLL) supplied with the driver. Applications can then be written which use the
functions available in the DLL to directly control the device.
The second driver type is the virtual COM port (VCP) driver. The VCP drivers emulate a standard
PC COM port. These can be communicated with in the same manner as any other COM port on
the PC.
Under Windows 98 and ME, the Found New Hardware Wizard should be used to install devices
when they are connected to the PC for the first time as this is the recommended procedure for
reliable device operation.

2.1 Installing D2XX Drivers
To install D2XX drivers for an FT232BM, FT245BM, FT8U232AM or FT8U245AM device under
Windows 98, follow the instructions below:
·
If a device of the same type has been installed on your machine before and the drivers that are
about to be installed are different from those installed already, the original drivers need to be
uninstalled. Please refer to the
Uninstalling FT232BM, FT245BM, FT8U232AM and FT8U245AM
Devices section of this
document for further details of this procedure.
·
Download the latest available D2XX drivers from the
FTDI website
and unzip them to a location
on your PC.
·
Connect the device to a spare USB port on your PC. This will launch the Windows Add New
Hardware Wizard. Windows may display a message reading "Building driver database" at this
point which may take a few minutes to pass. Click "Next" to proceed with the installation.
