Determining User's Sound Blaster Card

Sound Blaster cards can be distinguished by their DSP version numbers. The table
below lists the Sound Blaster cards and their respective DSP version numbers:
Cards
SB1.5, SBMCV
SB2.0
SBPRO, SBPRO MCV
SB16, Sound Blaster 16 with Advanced Signal Processing
The DSP version can be retrieved by issuing DSP command E1h. This will be
covered in the subsequent chapters.
There are two versions of SBPRO. The difference is in the FM chip used. The earlier
version uses a two-operator FM chip, while the later version uses a four-operator FM
chip. To distinguished them, you can read the value from I/O port 388h, two-operator
cards will return a value of 06h, and four-operator cards will return a value of 00h.
You should determine the actual card used by your user if your application is written
only for a specific card.
