PART 3 - Options for ALSNDB.SYS Sound Card Setup Program

        The following lists the available options for the ALSNDB.SYS
        sound card setup program. For example:

        DEVICE=C:\MMOS2\ALSNDB.SYS 1 D1 I5 A220 M4 /N:ALS01


        D1    :   The 'D' indicates the 8/16-bit DMA channel to be used.
                  For ALS100+ chip, only 8-bit DMA channel are available:
                        0, 1 and 3

        I5    :   The 'I' means interrupt, the available interrupts are
                  5, 7, 9, 10, and 11

        A220  :   'A' indicates the base IO address of DSP, available ports:
                  220, 240, 260, 280

        M4    :   DMA Buffer unit (1K per unit), M4 means 4K buffer used.

        ALS01 :   Phiscal Device Driver name
        
Notice !:
        1. Because the High Resolution Timer was used in this driver, while
           it is taking interrupts, DOS sessions (VDMs) will not receive INT 8
           or INT 1Ch calls.

        2. The installation process of ver.1.16 driver will replace the 
           older version of clock01.sys and clock02.sys with newer ones. 
           If you want to keep them, follow the steps described below:
                a. cd \OS2\BOOT
                b. mkdir BACK  (you can use another dir. name as you wish)
                c. copy clock*.sys BACK
