CD-ROM Audio in Windows 3.1

This is a complete description of the support for CD-ROM Audio in Windows 
3.1.  This article will try to completely explain the CD-ROM environment.  
It will also include a detailed list of things that need to be done to use 
Music CDs in your CD-ROM under Windows 3.1.

The support for CD-ROM Audio is a multilevel cooperation of three levels 
of drivers.  They are the manufacture's CD-ROM device driver, Microsoft's 
MSCDEX.EXE, and Windows 3.1 MCICDA.DRV.  These are the three drivers 
required to use the CD-ROM Audio support in Windows 3.1.  The manufacture's 
driver interfaces directly to the CD-ROM device.  It talks to MSCDEX.EXE.  
MSCDEX.EXE is the programmers Red Book CD Audio driver.  It talks to 
MCICDA.DRV of Windows 3.1.  MCICDA.DRV supports Windows applications using 
CD Audio.  It talks to Windows programs.  CD Wizzard(TM), a windows 
application, talks to MCICDA.DRV.

All three drivers must be installed and configured correctly to play music 
CDs.  When Windows 3.1 setup program is run, it checks for the presence 
of MSCDEX.EXE.  If it is found, it will create an entry for MCICDA.DRV in 
your system.  But, it will NOT install the driver!  This must be done by 
the user after the installation is completed.  CD Wizzard gives instructions 
on how to do this when it detects the situation.  Following are the exact 
steps to add all these drivers to your system:
	A) Add your manufacture's driver supplied with the CD-ROM Drive to 
		CONFIG.SYS.
	B) Add MSCDEX.EXE from manufacture or Microsoft to AUTOEXEC.BAT.
	C) Configure the above drivers for each other. Use the documentation 
		from manufacture.
	D) Go to Control Panel in windows and select Drivers Icon.
	E) Press the ADD Button.
	F) Select "[MCI] CD Audio" entry and press OK Button
	G) Insert Windows Disk asked for and follow instructions.
	H) Restart windows.  You should now be able to Run CD Wizzard to play 
		Music CDs.  If after the above steps you are still not getting 
		the MCICDA.DRV to run, follow these instructions:
			A) Edit SYSTEM.INI.
			B) Find the [MCI] section.
			C) There should be a "CDAudio=mcicda.drv" entry.  If not, add it.
			D) Save SYSTEM.INI and exit editor.
			E) Do a directory listing on your <windows>\SYSTEM directory.
			F) Is MCICDA.DRV present?  If not:
				1) Search Windows 3.1 Install disks for a file  
					"MCICDA.DR_".  On 3 1/2 HD it is #4.
				2) Use EXPAND.EXE command to expand file to <windows>\SYSTEM.
				3) Restart windows.

One major problem that we have seen with CD-ROM drives is that the lens 
pickup system gets dirty easily.  This can cause the CD-ROM drive to act 
very strange.  It will skip in playing songs, reset the drive, or not play 
a disk at all.  To clean a CD-ROM drive, a CD cleaning disk can be bought 
at most audio stores.  Run the disk through the drive.  This should solve 
the problem.  You should clean your drive at least every 60 days.
