Instructions for installing SONYB31A.ADD device driver for OS/2 versions
2.0 and 2.1:
        1)   Copy the file SONYB31A.ADD to the OS2 directory of the boot
             drive:

             ex.:  copy A:\SONYB31A.ADD C:\OS2\SONYB31A.ADD

        2)   Add the following line to your OS/2 CONFIG.SYS file:

                   BASEDEV=SONYB31A.ADD

            Note that it is not necessary to specify the full path to the
            file - OS/2 expects the file to be in the root directory or
            the OS2 directory.

        3)  The valid parameters and the associated actions are shown below.

    Parameter              Action
    ---------              ------
    /A:d                   Identifies a specific adapter, d
    /P:hhhh                Set base I/O port address for current adapter
                                (this should be a four-digit value - use
                                 leading 0's if necessary)
                                (default = 0340)
    /IRQ:dd                Set the interrupt level used to dd for current
                             adapter (default = none)
    /AT:dd                 Set the adapter type.  Current legal values are:
                           00 = Sony CDB-334 (default)
                           08 = Media Vision PAS-16

                For example, to access a CDB-334 host adapter at IO port 360h,
                use the following line in your OS/2 2.x CONFIG.SYS file:

                BASEDEV=SONYB31A.ADD /A:0 /P:0360

                To access a Media Vision PAS-16 adapter, use the following 
                line in your OS/2 2.x CONFIG.SYS file:
                
                BASEDEV=SONYB31A.ADD /A:0 /AT:08

                (the default port address for the CDU-31A in this case is
                 1F88h.)
