Solution:

The following is for your reference: 1. PCIA-71 and DACpad-71 are the same product, DACpad-71 is previous name. 2. Original DOS library and Win95 driver are designed for previous product name, so it will cause some problems while using them with new product name. 3. Due to 2nd item we modify the library and Win95 driver for the new product name, but users still have the chance to use the new library and driver with old DACpad-71. 4. We issue an utility "PCIA71.EXE" to help you to exchange product name between "DACpad-71" and "PCIA-71". 5. Any utility and driver on our website is suitable for PCIA-71, you'd better change DACpad-71 to PCIA-71 first before you use it.
