1/*  set_vector
2 *
3 *  This routine installs an interrupt vector on the target Board/CPU.
4 *  This routine is allowed to be as board dependent as necessary.
5 *
6 *  INPUT:
7 *    handler - interrupt handler entry point
8 *    vector  - vector number
9 *    type    - 0 indicates raw hardware connect
10 *              1 indicates RTEMS interrupt connect

12 *  RETURNS:
13 *    address of previous interrupt handler
