SB Pro; Adlib Registers
T he AD1815 contains sets of ISA Bus registers (ports) that correspond to those used by the Sound Blaster Pro audio card from Cre-
ative Labs and the AdLib audio card from AdLib Multimedia. T able IX lists the ISA Bus Sound Blaster Pro registers. T able X lists
the ISA Bus AdLib registers. Because the AdLib registers are a subset of those in the Sound Blaster card, you can find complete in-
formation on using both of these registers in the
