    TITLE:  Crystal Audio Drv CS4232C.EXE Load Slow

    SUMMARY

       When booting any system that is loading the Crystal Audio
       CS4232C.EXE driver in the CONFIG.SYS, the driver may take longer
       than 60 seconds to load.

       This issue applies all systems.

    ISSUE

       The specific configuration listed below causes the CS4232C.EXE
       driver to take longer to load than expected.

       1. DOS is loaded into upper memory blocks by using DOS=UMB in the
          CONFIG.SYS file.

       2. The Intel Plug-and-Play driver DWCFGMG.EXE is loading in the
          CONFIG.SYS file.

       3. CS4232C.EXE is loading in the CONFIG.SYS file.

    BACKGROUND

       The Crystal Audio chipset is a Plug-and-Play device. In this
       configuration, the CS4232C.EXE will load properly, however it
       takes a long time to read the resource information from the
       Plug-and-Play architecture of the system.

    ACTION

       Load the CS4232C.EXE in the AUTOEXEC.BAT instead of CONFIG.SYS.

       1. Delete the line containing CS4232C.EXE from the CONFIG.SYS file.

       2. Add the line below to the beginning of the AUTOEXEC.BAT file:

                C:\CRYSTAL\CS4232C.EXE /N
