3 *  This routine installs an interrupt vector using the basic
4 *  RTEMS mechanisms.  This implementation should be suitable for
5 *  most m68k based boards.  However, if the board has an unusual
6 *  interrupt controller or most somehow manipulate board specific
7 *  hardware to enable/disable, mask, prioritize, etc an interrupt
8 *  source, then this routine should be customized to support that.
