    		NO SOUND FROM Z-PLAYER CD-ROM ATTACHED TO POWEREXEC

    PROBLEM

    When a Zenith Data Systems Z-Player (external CD-ROM unit) Model ADR-0200 is
    attached to a PowerExec's parallel port, using IRQ 7, no sound will be heard
    from the Z-Player's speakers.

    CAUSE

    The Z-Player is not compatible with the PowerExec while using IRQ 7.

    SYSTEMS AFFECTED

    All PowerExecs systems.

    SOLUTION

    Edit the files CONFIG.SYS, AUTOEXEC.BAT, and/or SYSTEM.INI to allow the use
    of IRQ 5.

    1. The AUTOEXEC.BAT file must contains the following statements:

    	C:MSCDEX /D:MSCD000 /M:8 ;CD-ROM extension DOS driver
    	C:AUDCARD ;ESS audio card services client

    2. For the ADR-0200 Z-Player 2.0, do the following:

    a. With the ESS Installation ver 2.0 (PCMCIACD.SYS file size is 14576),
       within the CONFIG.SYS file, manually modify the following statement

    	DEVICE=C:\PCMCIACD.SYS /D:MSCD000 /N:1

       to read

    	DEVICE=C:\PCMCIACD.SYS /D:MSCD000 /N:1 /I=5

       Please note the "=" sign that is used in conjunction with the "I" parameter
       to set the interrupt value.

    b.  Next, manually edit the SYSTEM.INI file to read as follows:

    	SYSTEM.INI
    	[auddrive.drv]
    	AudioDrive=ES688
    	Synth=OPL3
    	port=220
    	int=5
    	dmachannel=1
    	(etc...)

    3. For the ADR-0200 Z-Player 3.0, do the following:

    When configuring the ESS Z-Player 3.0 Installation, simply change to the
    PCAUDIO directory and run ZCONFIG (updates both CONFIG.SYS and SYSTEM.INI
    files). You will be prompted for the interrupt, DMA channel, and the name of
    the Windows directory.

    Reboot the system for the changes to take effect.

    NOTE:  It is worth noting that the CONFIG.SYS statement is different with the
    version 3.0 PCMCIACD.SYS file (14864 bytes):

    	DEVICE=C:\PCMCIACD.SYS /D:MSCD000 /N:1 /I:5 /A:1

    Note that all switches use ":" and the addition of the "/A" parameter that
    selects the DMA channel being used.
