/*

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