Microsoft Windows uses installable device drivers for hardware-specific support. In addition to the standard device entries in the SYSTEM.INI file, Windows introduces another convention: the use of &quot;driver specific&quot; parameters on the driver entry. For example, an entry in the SYSTEM.INI file might look like the following:

  [mci] cdaudio=mcicda.drv waveaudio=mciwave.drv 4 The &quot;waveaudio=&quot; entry has both the driver name, MCIWAVE.DRV, and an extra parameter that is specific to the MCI Wave driver (4). In this example, &quot;4&quot; is the number of seconds of wave data the MCI Wave driver buffers.

Because the driver can store the parameter on the same line of the SYSTEM.INI file as the driver name, a new section of the SYSTEM.INI file to store driver parameters is not required.

The user can change this parameter through the Drivers application in the Control Panel by performing the following three steps:


 * 1) In the Control Panel window, choose the Drivers icon
 * 2) Select the MCI Wave driver
 * 3) Choose the Setup button.
