Fix : The VC demo "DaCal" (with calibration) calling the wrong 
      function "PIODA_Voltage()" and "PIODA_Current()". Fix it
      to call the "PIODA_CalVoltage()" and "PIODA_CalCurrent()".

Fix : The internal function PIODA_ReadEEPROMAll() computes the
      wrong delta-value for Current-Output, and causes the 
      PIODA_CalCurrent() function output the wrong data. Fix it.

for Windows 98/NT
Fix : PIODA_ActiveBoard() function just can used to active the
      board for 0 to 3 under Windows NT. Fix it to 16.

Fix : Output the 0x01 to Base-Address will not allow the program
      to uses the DA functions. Fix to output the 0x11 to Base-
      Address to enable it.

Change : Remove the PIODAu.PAS, PIODAu.CPP, PIODAu.BAS files.
      And move the PIODAu_XXX() function into the DLL file with
      the prefix "PIODA_" to be the function name.

Change : In the PIODA_SearchCard() function, it will automatically
      call the PIODA_ReadEEPROMAll() for the each card that found.
      And, will automatically enable the each card to be allow to
      uses the DI,DO,DA,EEPROM functions. 

      Thus, the PIODA_ReadEEPROMAll() doesn't have to be called 
      any more. And, the user doesn't have to enable these cards.

Change : Change the first parameter to be wBoardNo for the following 
      functions: 
           PIODA_DI(),          PIODA_DO(),          
           PIODA_Voltage(),     PIODA_Current(),  
           PIODA_CalVoltage(),  PIODA_CalCurrent()

      Thus, the user doesn't have to call the PIODA_GetConfigAddressSpace()
      function to get the base-address. The user just have to indicate 
      which board to active.

Change : The PIODA_DI() function be changed to 
     EXPORTS WORD CALLBACK PIODA_DI(WORD wBoardNo, DWORD *wVal);

Fix : To support the Multi-Board access.
      > Change the buffer to 2-dimension.

Fix : Change the variable-name (on the PIODAu.XXX file) with 
      prefix "PIODAu_".

Fix : The program must call the function PIODAu_ReadEEPROMAll() 
      once before other PIODAu_XXX series function be called.

Change : The first parameter for almost all of the function with 
      prefix "PIODAu_" is changed to wBoardNo. Which is used to 
      indicate the Board-Number that the program wants to access.
      Please ensure that the program has call the function 
      PIODAu_ReadEEPROMAll() once before other PIODAu_XXX series
      function be called.

Fix : The Voltage-Output and Current-Output uses the same channel. 
      Thus, the program can't uses the Voltage-Output and Current-
      Output to the same cannel at the same time. Fix the demo 
      programs and Diagnostic program.

Add : Add the "EEPROM write to file" and "EEPROM restore from file" 
      feature to the Diagnostic program "Diag.exe". The user can 
      find the feature on the menu of "EEPROM".

Note : It's recommend to use the feature "EEPROM write to file" 
      to backup the EEPROM data to an file.
