Description eda 1999-10-21 12:27:09 EDT
[root@eda /root]# tunelp /dev/lp0 -i 7
tunelp: ioctl: Invalid argument
/dev/lp0 using IRQ -1
[root@eda /root]#

Tunelp does not work for me. Great loss of printer
performance - it works very badly with I/O polling.

Try adding to your /etc/conf.modules:

options parport_pc io=0x378 (or whatever) irq=7

You can even add a 'dma=<some dma channel>'

Alternatively, do 'echo 7 > /proc/parport/0/irq', I think.
