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 Silabs Interrupt Driver's source files are located. 3.) Type "Build -cZ" and press enter. 4.) The built driver will be located in the subdirectory "Driver_Source\objchk\i386". 2.1 Building a driver compatible with Windows 98 Second Edition --------------------------------------------------------------- 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. SOURCES=intusb.c \ intpnp.c \ intpwr.c \ intdev.c \ intwmi.c \ intrwr.c \ intwdm98.c \ intusb.rc 3.) Continue by following the instructions in section 2.0 above to build the driver. 3.0 REVISION HISTORY -------------------------------------------------------- Version 1.3 Overflow bug fixed. The issue was only apparent when making very frequent read requests over a long interval using multiple threads where no data ever becomes available. The resolution limits the number of outstanding requests that the driver will queue. Version 1.2 Install bug in Windows 98 fixed. Version 1.1 Support for Windows 98 added. Support for Dual Processor Machines added. Version 1.0 Initial release.
