You will need to remove the modules with depend on it first.

If it's compiled into the kernel, it should be possible to disable it by using the kernel option "parport=0" when you boot the kernel. > This should allow the parallel port module to be installed with the correct > base address for the parallel port. > > I believe that 0x278 is reserved for use by the parallel port as is 0x378. > Since your parallel port is using 0x378, using 0x278 is probably binding the > comedi driver to an unused address space - hence nowt is gonna happen!

I'd pick "Bi-directional" as it's the most basic mode (apart from "Disabled" :-). -- -=( Ian Abbott _at_ MEV Ltd.
