In order to build the Cygnal Interrupt Device Driver you must have the Microsoft Windows XP Driver
Development Kit installed. Use the build utility included with the DDK to build the driver. Please 
refer to the DDK documentation section "Using the Build Utility" under the "Driver Development Tools"
section before attempting to build the driver. Using these methods the built driver will be compatible
with Windows 2000 and Windows XP.
 
1.) Open the "Win XP Checked Build Environment"

2.) Navigate to the directory where the Cygnal Interrupt Driver's source files are located.

3.) Type "Build -cZ" and press enter.

4.) The built driver will be located in the subdirectory "CygnalInt\objchk\i386".

1.) Open the file intusb.h and uncomment the line:

	//#define WIN98DRIVER

2.) Open the sources file with an editor(e.g.Notepad) and add the file intwdm98.c to the list of sources at the end of the file. The sources section will now look like the following.
