        Bravo MS Pentium Unable to remove "Unknown Cards" from ISACU Device List
    			and Failed NVS Write Error

    PROBLEM

    1. While booting the Bravo MS Pentium system, the ISA Configuration
       Utility (ICU) adds "Unknown Cards" into the device list; these cards are
       unable to be removed.

    2. With PnP adapters installed, the Bravo MS Pentium system may report the
       following error at boot:

    		      "Failed NVS Write Error = 1h"

    CAUSE

    Bravo system BIOS version 1.04 (p/n 905558-039 or below) is not compatible
    with ICU version 1.02 (p/n 911370-035 and 911370-036).

    SOLUTION

    Download the Clearnvs Utility Diskette (p/n 912493-031 version 1.00) and run
    the CLEARNVS.EXE file to clear the non-volatile RAM.  File 12493031.EXE can be
