The following table contains specific resource ordering for specific components of each device.
Note The resource sets for following multimedia devices are order dependent, particularly within a class of resource. The drivers included with Windows 95 parse the resource set based on class, size and ordinal of the resource.
The location of these components in I/O space is not a criterion for the parsing algorithm. This allows the device to "float" in I/O space when all optimal resource settings are in conflict.

Plug and Play implementations of the Windows Sound System designs should not include the "AutoSelect" range (for example: 530-533) in the base I/O resource descriptor. The reported range for the base address should be the CODEC only. Thus, a resource set for an ISA Plug and Play implementation of a WSS compatible device would contain:
If the implementation provides additional hardware support for Sound Blaster compatibility and shares the DAC/ADC I/O path and IRQ/DMA resources with the WSS register plane (such as the Crystal Semiconductor CS4232 design), the resource set should contain both the CODEC and the Sound Blaster compatibility resources, as follows:
Again, please note that the above I/O resources structures are order-dependent. The standard device drivers shipped with Windows 95 handle the above cases correctly.
If your hardware implementation uses the ESS reference designs without modification, you may use the listed ESS device IDs as compatible device tags. However, if your implementation deviates from the ESS reference design, particularly with IRQ and DMA steering, you will need to create your own .INF files and include special IRQ/DMA steering information in these files. Please contact ESS Technology, Inc. or the Microsoft Hardware Vendor Relations Group for further information.
