[Linux-parport] open("/dev/parport", O_RDWR) results in "no such device"

[christoph_meissner at idg.de]

Hello to all parport list-members

as ill luck would have it
I am trying to configure my parport for a linux-2.4.24 kernel.

Expecting everything is easy,
I adequately set up my BIOS and kernel configuration
and loaded the modules parport and parport_pc.
Hopefully I opened the /dev/parport0 device-file
with a little perl-skript
and it happened exactly as I expected: nothing worked.

The message I receive when opening the device file is: "No such device."

My configururation and steps to achieve a valid parport-open are listed
below.

It would be great,
if anyone can assist me trouble-shooting this.

Christoph

This is how I opened the device
after loading the appropriate modules (see below).

root> perl
open(IN, "+</dev/parport0") || die "/dev/parport0: $!\n";

results in:

/dev/parport0: No such device


This is my configuration:

Motherboard: Asus P4P800

BIOS settings:
parallel-mode     Bidirectional
Address           0x378
IRQ               7
