# -------------------------------------------- # 03/11/15 ambx1@neo.rr.com 1.1449 # [PnPBIOS] make /proc interface an optional feature # # The PnPBIOS /proc interface provides direct access to PnPBIOS calls. # These calls can be potentially dangerous, especially on buggy systems. # Therefore, this patch provides an option for PnPBIOS calls to be # managed by the PnPBIOS driver exclusively. This patch also updates # the KConfig documentation accordingly. # -------------------------------------------- # diff -Nru a/drivers/pnp/Kconfig b/drivers/pnp/Kconfig --- a/drivers/pnp/Kconfig Sun Nov 16 00:25:01 2003 +++ b/drivers/pnp/Kconfig Sun Nov 16 00:25:01 2003 @@ -30,33 +30,9 @@ comment "Protocols" depends on PNP -config ISAPNP - bool "ISA Plug and Play support (EXPERIMENTAL)" - depends on PNP && EXPERIMENTAL - help - Say Y here if you would like support for ISA Plug and Play devices. - Some information is in <file:Documentation/isapnp.txt>. +source "drivers/pnp/isapnp/Kconfig" - If unsure, say Y. - -config PNPBIOS - bool "Plug and Play BIOS support (EXPERIMENTAL)" - depends on PNP && EXPERIMENTAL - ---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 used. - - Note: ACPI is expected to supersede PNPBIOS some day, currently it - co-exists nicely. - - See latest pcmcia-cs (stand-alone package) for a nice "lspnp" tools, - or have a look at /proc/bus/pnp. - - If unsure, say Y. +source "drivers/pnp/pnpbios/Kconfig" endmenu diff -Nru a/drivers/pnp/isapnp/Kconfig b/drivers/pnp/isapnp/Kconfig --- /dev/null Wed Dec 31 16:00:00 1969 +++ b/drivers/pnp/isapnp/Kconfig Sun Nov 16 00:25:01 2003 @@ -0,0 +1,11 @@ +# +# ISA Plug and Play configuration +# +config ISAPNP + bool "ISA Plug and Play support (EXPERIMENTAL)" + depends on PNP && EXPERIMENTAL + help + Say Y here if you would like support for ISA Plug and Play devices. + Some information is in <file:Documentation/isapnp.txt>. + + If unsure, say Y. diff -Nru a/drivers/pnp/pnpbios/Kconfig b/drivers/pnp/pnpbios/Kconfig --- /dev/null Wed Dec 31 16:00:00 1969 +++ b/drivers/pnp/pnpbios/Kconfig Sun Nov 16 00:25:01 2003 @@ -0,0 +1,41 @@ +# +# Plug and Play BIOS configuration +# +config PNPBIOS + bool "Plug and Play BIOS support (EXPERIMENTAL)" + depends on PNP && EXPERIMENTAL + ---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.
