+config PNPBIOS
+       bool "Plug and Play BIOS support"
+       depends on ISA && X86
+       default n
+       ---help---
+         Linux uses the PNPBIOS as defined in "Plug and Play BIOS
+         Specification Version 1.0A May 5, 1994" to autodetect built-in
+         mainboard resources (e.g. parallel port resources).
+
+         Some features (e.g. event notification, docking station information,
+         ISAPNP services) are not currently implemented.
+
+         If you would like the kernel to detect and allocate resources to
+         your mainboard devices (on some systems they are disabled by the
+         BIOS) say Y here.  Also the PNPBIOS can help prevent resource
+         conflicts between mainboard devices and other bus devices.
+
+         Note: ACPI is expected to supersede PNPBIOS some day, currently it
+         co-exists nicely.  If you have a non-ISA system that supports ACPI,
+         you probably don't need PNPBIOS support.
+
+config PNPBIOS_PROC_FS
+       bool "Plug and Play BIOS /proc interface"
+       depends on PNPBIOS && PROC_FS
+       ---help---
+         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.
