If you look through the pc386 bsp you'll find numerous calls to
BSP_install_rtems_irq_handler:

[nicks at titan pc386]$ find . -name *.c -exec grep --with-filename
BSP_install_rtems_irq "{}" \;
./3c509/3c509.c:  st = BSP_install_rtems_irq_handler( &sc->irqInfo );
./clock/ckinit.c:  if (!BSP_install_rtems_irq_handler (&clockIrqData)) {
./clock/ckinit.c:      if (!BSP_install_rtems_irq_handler (&clockIrqData)) {
./console/console.c:      status =
BSP_install_rtems_irq_handler(&console_isr_data);
./console/console.c:      status =
BSP_install_rtems_irq_handler(&console_isr_data);
./ne2000/ne2000.c:  if (! BSP_install_rtems_irq_handler (&irq))
./wd8003/wd8003.c:  st = BSP_install_rtems_irq_handler (&sc->irqInfo);

Hello, 
I'm trying to catch IRQ7 in the pc386 BSP both under C and under Ada. Could
anyone tell me how to catch it, please? 
Thanks,
