Use menuconfigs instead of menus, so the whole menu can be disabled at once instead of going through all options.

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.
