Hi everybody,
I recently added a sound card to my Linux box and had to
remove/reconfigure my printer setup due to an irq conflict at irq 5 (The
printer was set to irq 5 and ioport 378 and the sound card needed irq 5
to function). Anyway, the sound card installation went great and I now
enjoy using some of the multimedia applications that you can get for
Linux ;)
However, I apparently created a system problem I am having difficulty
solving. I cannot get my parallel port to function. I reconfigured the
parallel port (parport) to use irq 7 and ioport 378. Easy enough.
However when I go and look at the irq listing in /proc/interrupts using
the commmand:
cat /proc/interrupts, irq 7 is not listed. However, the command: cat
/proc/ioports shows the correct ioport address of 378. When I print, the
print que complains that it cannot open '/dev/lp1' - device not
configured. This makes sense in that parport has no irq assigned to it
that can be seen in /proc/interrupts. My question is why can't I
configure irq 7? it's a free resource... What am I doing wrong? On this
particular machine, I am running Caldera OpenLinux 2.3. Any help is much
appreciated.
Best
M. Peck Dickens
