Hello,

I`m trying to configure my hp deskjet 520 and i`m running into some 
trouble.
The handbook says it all has to do with the interupt driven 
configuration, it does not work with some new hp printers.
I have to switch to the polled mode.

"If you want polled mode, remove in your /boot/device.hints file, the 
following line: hint.ppc.0.irq="N"".
Then they say i have to rebuild my kernel.

Now i ask myself what the /boot/device.hints file has to do with my 
kernel.
What sort of file is /boot/device.hints and why do i have to rebuild my 
kernel.

Thanks inadvance,
Justin.
