6.3.7. IDE / ISA DYNAMIC DEMULTIPLEXING
Some of the ISA bus signals are dynamically
multiplexed to optimize the pin count.
Figure 6-13. Typical IDE / ISA Demultiplexing
6.3.8. BASIC AUDIO USING IDE INTERFACE
When the application requires only basic audio
capabilities, an audio DAC on the IDE interface
can avoid using a PCI-based audio device(see

describes how to implement the external glue logic
to demultiplex the IDE and ISA interfaces. In Local
Bus mode the two buffers are not needed and the
NAND gates can be simplified to inverters.
