+modification history
+--------------------
+01g,29apr10,pad  Moved extern C statement after include statements.
+01f,10dec97,ms   added prototype for usrFdConfig
+01e,31aug95,hdn  added error code,
+		 FD_UNFORMATED FD_WRITE_PROTECTED FD_DISK_NOT_PRESENT
+01d,25oct94,hdn  added FD_RAW structure for fdRawio().
+		 added fdRawio() function declarations.
+01c,22apr94,hdn  moved FD_DMA_BUF, FD_DMA_BUF_SIZE to config.h.
+01b,06apr94,hdn  changed the DMA address from 0x1000 to 0x2000.
+01a,30sep93,hdn  written.
