20  * a supported board if the I/O base is left unspecified with comedi_config.
21  * However, many of the isapnp id numbers are unknown. If your board is not
23  * modprobe the isa-pnp module for /proc/isapnp to exist) so the id numbers
24  * for your board can be added to the driver.
26  * Otherwise, you can use the isapnptools package to configure your board.
27  * Use isapnp to configure the I/O base and IRQ for the board, and then pass
40  * (scan_begin_arg, etc.) maps to PFI0 - PFI9.
