+/* set_vector
+ *
+ * This routine installs an interrupt vector on the target Board/CPU.
+ * This routine is allowed to be as board dependent as necessary.
+ *
+ * INPUT:
+ * handler - interrupt handler entry point
+ * vector - vector number
+ * type - 0 indicates raw hardware connect
+ * 1 indicates RTEMS interrupt connect
+ *
+ * RETURNS:
+ * address of previous interrupt handler
