The following topics are covered in this READ.ME file : 1) Installing on top of previous installations 2) System Requirements 3) Files List for Crystal Audio Install Disk 4) Crystal Audio for OS/2 Installation Procedure 5) Device Driver Command Line Options 6) Notes on Command Line Options 7) Using Audio in DOS and Win-OS/2 Sessions 8) Audio Concurrency Issues - OS/2, DOS, Win-OS/2 9) Plug and Play System Issues 10) Mixer Issues 11) MIDI Issues 12) Installing Win-OS/2 Drivers 13) Installing the IBM OPL3 Driver (FM Synthesis) in Warp 4.0 14) Installing the IBM MPU-401 Driver in Warp 4.0 1) Installing on top of previous installations ----------------------------------------------------------------------------- Prior to installing, check if the following lines exists in CONFIG.SYS: BASEDEV=CS31CONF.SYS ... BASEDEV=CS32CONF.SYS ... DEVICE=C:\MMOS2\CSBSAUD.SYS ... DEVICE=C:\MMOS2\VCSBSAUD.SYS BSAUD1$ DEVICE=C:\MMOS2\VCSGAMES.SYS BSAUD1$ If any of these entries are present, delete them prior to installing this product. 2) System Requirements ----------------------------------------------------------------------------- Before you install Crystal Audio for OS/2, check to see if you have the version of MMPM/2 as shipped with OS/2 Warp 4.0 (Merlin), installed on your system. Use the SYSLEVEL command to determine which level of MMPM/2 you have installed. The "Current CSD Level" field displays one of the following values: UN0000 - The version of MMPM/2 as shipped with OS/2 2.1. An update is required. UN49407 - The October 1993 CSD version of MMPM/2. An update is required. This is the same version for the OS/2 2.11 service refresh of February 1994. XR03000 - The version of MMPM/2 as shipped with OS/2 Warp 3.0. An update is required. If an update is required, the MMPM/2 CSD can be obtained free from Compuserve or from the IBM OS/2 BBS.

Open the OS/2 System folder on the OS/2 desktop. Next open the Install/Remove folder. Start the Multimedia Application Install program which is located in the Install/Remove folder. Alternatively, you can execute MINSTALL from an OS/2 command prompt. Once you are in the multimedia installation program, select Source Drive A: (or whichever drive Crystal Audio for OS/2 diskette is in). The installation program will show a two Crystal Audio devices in the Features column: CS4232/36/37... Select the device that applies to the Crystal Audio device installed on your system. Do NOT select more than one Crystal Semiconductor Audio device. A check mark will appear next to the feature(s) selected. Click the install button to proceed with the installation. Read and follow the instructions provided by the installation program. The following files will be moved onto your system, based on the devices selected : \MMOS2\DLL\CARDINFO.DLL \MMOS2\DLL\BSAUDRES.DLL \MMOS2\HELP\CWAUDIO.HLP \MMOS2\CWAUDIO.SYS \MMOS2\CWAUDIO.INI \MMOS2\CWAUDIO.BIN \MMOS2\CWVAUDIO.SYS \OS2\CWCONFIG.SYS Based on your responses to input panels, several lines will be added to the OS/2 CONFIG.SYS file. If you do not know how to respond to the input panels, it is best to NOT change the default settings and click the OK button. The following describes the modifications made to your OS/2 CONFIG.SYS file if no settings are modified, based on the device selected : BASEDEV=CWCONFIG.SYS /P:534 /I:5 /D:1,1 /SB:220 /M:NONE /FM:NONE /J:NONE /CD:NONE DEVICE=C:\MMOS2\CWAUDIO.SYS /N:BSAUD1$ /L:8 DEVICE=C:\MMOS2\CWVAUDIO.SYS BSAUD1$ 5) Device Driver Command Line Options ----------------------------------------------------------------------------- The following tables describe the various command line options and setting available for the Crystal Audio device drivers.
