After you modify the NDIS miniport object identifier functions, modify the PhyDetect and SetupPhy functions.

To filter local variables in the NDIS miniport driver PhyDetect and SetupPhy functions

In %_WINCEROOT%\Platform\%_TGTPLAT%\Drivers\CENDISMiniport, open Physet.c.
Use DBG to conditionally declare the local variables related to debugging in the PhyDetect function definition.

The following code example shows how to conditionally declare the local variables.
```
#if DBG
    USHORT  MdiControlReg; 
    USHORT  MdiStatusReg;
#endif
```
In the SetupPhy function definition, exclude the local variables not needed by the Windows Embedded CE NDIS miniport driver.

The following code example shows how to exclude these variables.
```
#ifndef UNDER_CE    
    USHORT   LastMdiMiscReg;
#endif
    UINT     PhyId;
    BOOLEAN  ForcePhySetting = FALSE;
#ifndef UNDER_CE    
    UINT     i;
#endif
```
From the IDE Build menu, choose Open Build Release Directory.
Navigate to the directory containing your Windows Embedded CE NDIS miniport driver.

Be sure your NDIS miniport driver is in %_WINCEROOT%\Platform\%_TGTPLAT%\Drivers\CENDISMiniport.
Build the Windows Embedded CE NDIS miniport driver with the Build tool.

For more information about the Build tool, see Build Tool. Microsoft recommends using the -c parameter with the Build tool to delete all object files.
