The search path is soft to hard ( Y:, X:, W:, ..., C:, B:, A:, Z:) and if two or more files have the same name the first one found is used. This means that files in the ROM (Z:) can be replaced with files on user drives. </p> <p>Rasterizers are identified by their signatures: the second UID is <codeph>KUidOpenFontRasterizerValue</codeph> and they have the extension <filepath>.DLL</filepath>. </p> <p>To install a font rasterizer DLL: </p> <ul><li id="GUID-05B1DCC7-616E-518D-8E22-7D88BBEBBB75"><p>Copy it into <filepath>\sys\bin\</filepath> on any drive. </p> </li> <li id="GUID-8D9C4F93-8795-597C-80D0-26438AC61317"><p>Restart the device to restart the Font and Bitmap server. </p> <p>Note: there is no way to load a rasterizer without a restart.
