------------------------------------------------------------------------
Before You Begin
------------------------------------------------------------------------
If you already have a WDM-style driver installed (whether you or the
operating system installed it), make sure you uninstall the driver
before installing a different one, unless you are using the installer
program. For details, see "Uninstalling the Driver."
------------------------------------------------------------------------
Installing the Driver using the automatic installer program
------------------------------------------------------------------------
There is an install program included with this driver set, contained in
the files "Setup.exe", "Setup1.dll", and "Setup2.dll". To install using
this program, extract these three files, along with all of the driver
files to a temporary directory, Then run the Setup.exe program. The main
window of the program will give you a button called "Install" and one
called "Remove". Pushing "Install" will remove the old driver, if one
exists, and install this driver. Pushing "Remove" will remove a Crystal
driver if one is presently installed. You do not have to remove a driver
before installing this one, the program will do that automatically.
