_{hardware_model}_{action_name}. e.g. _725X_Initial ().
(where “725X” is “7250” for PCI-7250 and “7252” for cPCI-7252.)
In order to recognize the difference between DOS library and Windows
95 library, A capital "W" is put on the head of each function name of
the Windows 95 DLL driver. e.g. W_7250_Initial ()
The detailed description of each function are specified in the following
