General Information:
--------------------
1.  This kit has two main additions from the last general update (1.51):
a new ADD (CWCONFIG.SYS) and a new installation. The installation
integrates the Warp and Merlin driver installs into a single diskette,
and also, Crystal Win 3.1x drivers are installed automatically for Win-OS/2.
Overinstallations/reinstallations are possible with this kit.  The ADD
driver (CWCONFIG.SYS) now recognizes CS4236's as a system device node.


New Features in Version 1.60:
-----------------------------
CWCONFIG.SYS:
        1.  Added logic to detect CS4236's system device nodes.
        2.  Version upgraded to 1.52 from 1.51.

CWAUDIO.SYS:
	1.  No changes; Version remains 1.51.

VCSBSAUD.SYS:
	1.  No change; Version remains 1.51.

INSTALL:
        1.  Upgrade version to 1.60 from 1.51.
	2.  Integrate Warp and Merlin installs into a 
	    single diskette. For Warp system, this requires
	    obtaining files from Warp fixpack #27. 

	   \OS2\BOOT\RESOURCE.sys       // PnP aware resource manager
	   \OS2\BOOT\CLOCK01.sys        // 1 ms timer support
	   \OS2\BOOT\CLOCK02.sys        // 1 ms timer support
	   \OS2\BOOT\TIMER0.sys         // 1 ms timer support
	   \MMOS2\DLL\AMPMXMCD.dll      // DART support (games API)
	   \MMOS2\DLL\AUDIOIF.dll       // DART support (games API)

	3.  Remove all Crystal dialog boxes from install.
        4.  Have Win-OS/2 drivers installed when Crystal
            Drivers for OS/2 are installed (Full Pack, Connect, and Merlin).
        5.  Provide overinstallation/reinstall of the Crystal OS/2 
	    driver by cleaning up MMPM2.INI and CONFIG.SYS.
        6.  Have Minstall show Audio/FM installation preselected.
