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.
