The following files are changed by the installation program: 

CONFIG.SYS
The following lines are added to "config.sys": 

  DEVICE=\TBEACH\CDSETUP.SYS /T:I
  DEVICE=\TBEACH\TB-IDE.SYS /D:MSCD001
  LASTDRIVE = Z

These lines
* Run the CD-ROM port initialization program which makes sure the IDE port 
  on the sound card is on. 
* Load the device driver which loads the code for the IDE drive. 
* Set the last available drive letter (the setting of "z" is good because it 
  will prevent problems with networks and the like.)  

AUTOEXEC.BAT
The following lines are added to "autoexec.bat": 

  \TBEACH\MSCDEX.EXE /D:MSCD001 /L:E /M:12 /V
  SET SOUND16=\TBEACH
  \TBEACH\SNDINIT /B
  SET BLASTER= Axxx Ixx Dx T4

These lines
* Load CD extensions that tells DOS how to communicate with the IDE drive 
  (note how the "/D:" parameter MUST match). 
* Run the sound card initialization program. 
* Set the Sound Blaster(TM) settings.
