How to enable IRQ7 for parallel port on FC2 ?

[Hannes Mayer <h.mayer@xxxxxxxx>]

Hi all!

I've compiled RTAI with kernel 2.6.7 and wrote a hard real-time
kernel module for detecting the parallel port interrupt on pin 10 (ACK).

According to /proc/interrupts IRQ7 is not enabled:

[root@mag proc]# cat interrupts
           CPU0
  0:    2057096          XT-PIC  timer
  1:          8          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  8:          1          XT-PIC  rtc
 10:          0          XT-PIC  uhci_hcd
 11:       3848          XT-PIC  eth0
 12:        138          XT-PIC  i8042
 14:       6299          XT-PIC  ide0
NMI:          0
ERR:          0

How do I enable IRQ7 for the parallel port on FC2 ?

Thanks a lot in advance!

Cheers,
Hannes.
