How to enable IRQ7 for parallel port on FC2 ?

[Hannes Mayer]

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 at 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.
