    	 ADVANTAGE! ADVENTURE XXXX LOSS OF DATA IN SETUP AFTER RUNNING
    						  CD-ROM GAMES

    PROBLEM

    After running certain CD-ROM games on the Advantage! Adventure XXXX, the
    system may experience a loss of time, date, and hard disk data once the
    machine is turned OFF and restarted.

    CAUSE

    Certain CD-ROM games such as "Doom" attempt to access memory that is allocated
    to video shadow RAM.  This shadowing can not be disabled and may cause
    conflicts such as those documented above.

    SYSTEMS AFFECTED
    AST PART NUMBER AND DESCRIPTION

    SOLUTION

    excluded in the EMM386 statement of the CONFIG.SYS file.
