Help text

If you say Y here and to "/proc file system support", you will be able to directly access the PNPBIOS. This includes resource allocation, ESCD, and other PNPBIOS services. Using this interface is potentially dangerous because the PNPBIOS driver will not be notified of any resource changes made by writing directly. Also some buggy systems will fault when accessing certain features in the PNPBIOS /proc interface (e.g. "boot" configs).

See the latest pcmcia-cs (stand-alone package) for a nice set of PNPBIOS /proc interface tools (lspnp and setpnp).

Unless you are debugging or have other specific reasons, it is recommended that you say N here.
