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!

4config PNPBIOS
5 bool "Plug and Play BIOS support (EXPERIMENTAL)"
6 depends on PNP && ISA && X86 && EXPERIMENTAL
7 default n
8 ---help---
9 Linux uses the PNPBIOS as defined in "Plug and Play BIOS
10 Specification Version 1.0A May 5, 1994" to autodetect built-in
11 mainboard resources (e.g. parallel port resources).
12
13 Some features (e.g. event notification, docking station information,
14 ISAPNP services) are not currently implemented.
15
16 If you would like the kernel to detect and allocate resources to
17 your mainboard devices (on some systems they are disabled by the
18 BIOS) say Y here. Also the PNPBIOS can help prevent resource
19 conflicts between mainboard devices and other bus devices.
20
21 Note: ACPI is expected to supersede PNPBIOS some day, currently it
22 co-exists nicely. If you have a non-ISA system that supports ACPI,
23 you probably don't need PNPBIOS support.
24
25config PNPBIOS_PROC_FS
26 bool "Plug and Play BIOS /proc interface"
27 depends on PNPBIOS && PROC_FS
28 ---help---
29 If you say Y here and to "/proc file system support", you will be
30 able to directly access the PNPBIOS. This includes resource
31 allocation, ESCD, and other PNPBIOS services. Using this
32 interface is potentially dangerous because the PNPBIOS driver will
33 not be notified of any resource changes made by writing directly.
34 Also some buggy systems will fault when accessing certain features
35 in the PNPBIOS /proc interface (e.g. "boot" configs).
36
37 See the latest pcmcia-cs (stand-alone package) for a nice set of
38 PNPBIOS /proc interface tools (lspnp and setpnp).
39
40 Unless you are debugging or have other specific reasons, it is
41 recommended that you say N here.
