StartIO.exe contains the following files:

This driver provides an example of a minimal driver. Neither it nor the sample programs are intended to be used in a production environment. Rather, they are intended for educative purposes and as a skeleton driver.

Building the Driver and Examples

To compile the device driver:

  1. Start the checked or free build environment MS-DOS box.


  2. Run Build. This invokes the Microsoft make routines, which produce log files called Build.wrn and Build.log. The .wrn file contains warnings that no components have been extracted from certain libraries, even if the build succeeds. If the build succeeds, the driver can be found in the %basedir%\lib\i386\free or %basedir%\lib\i386\checked directory.


  3. Copy the SYS file to %systemroot%\SYSTEM32\DRIVERS directory where all the Windows NT device drivers are stored.


To install the Sample driver, use the REGINI utility to create the entries listed in the .ini file.

Testing

  1. Restart your computer.


  2. Start the driver with "net start".


  3. Run Testapp.
