Ok, so thats one mystery cleared up. But it doesn't solve my problem.
Let me explain what I do. I look in windows what io range the card uses.
Then I reboot in linux.
I insmod parport and insmod parport_pc io=what-I-found-in-windows irq=none
then I run the following code as root:
ioperm(what-i-found-in-windows,8,1);
outb(1,what-i-found-in-windows);
sleep(1);
outb(0,what-i-found-in-windows);
ioperm(what-i-found-in-windows,8,0);
I have an array of leds connected to the data pins of the parallel port
and with a 1k resistor in series to the ground pin.
Nothing happens. In a desperate attempt I also tried it with the onboard
port and nothing happened as well.
Help would be appreciated.
