Interrupt handling

I have special hardware card for some puprose which can generate interrupts from IRQ1 to IRQ7. Interrupt number can be selected by setting appropriate jumper on card.
Problem: I set IRQ5 which corresponds to interrupt vector 0dH . I have LPT2 on this IRQ.
Question : Can I handle interrupt if another device already uses it ? Should LPT2 be disabled ?

You should be able to use IRQ5 for this purpose even if LPT2: is present.  The LPT ports don't use the interrupts even if there is a printer on the port.  Often, however, Soundblaster (and compatible) sound cards are using IRQ5 so if you have a sound card you may want to double check which IRQ it's using.
