Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

config PNPBIOS
bool "Plug and Play BIOS support (EXPERIMENTAL)"
depends on PNP && ISA && X86 && EXPERIMENTAL
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.
