1865 Find out whether you have a PCI motherboard. PCI is the name of a
1866 bus system, i.e. the way the CPU talks to the other stuff inside
1867 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
1870 The PCI-HOWTO, available from
1871 <http://www.tldp.org/docs.html#howto>, contains valuable
1872 information about which PCI hardware does work under Linux and which

1882 # ISA support is now enabled via select. Too many systems still have the one
1883 # or other ISA chip on the board that users don't know about so don't expect
1884 # users to choose the right thing ...
1894 depends on HW_HAS_EISA
1897 The Extended Industry Standard Architecture (EISA) bus was
1898 developed as an open alternative to the IBM MicroChannel bus.
1900 The EISA bus provided some of the features of the IBM MicroChannel
1901 bus while maintaining backward compatibility with cards made for
1902 the older ISA bus. The EISA bus saw limited use between 1988 and
1903 1995 when it was made obsolete by the PCI bus.
1905 Say Y here if you are building a kernel for an EISA-based machine.

1916 processors. Documentation on writing device drivers for TurboChannel

1945 bool "Use 64-bit ELF format for building"
1948 A 64-bit kernel is usually built using the 64-bit ELF binary object
1949 format as it's one that allows arbitrary 64-bit constructs. For
1950 kernels that are loaded within the KSEG compatibility segments the
1951 32-bit ELF format can optionally be used resulting in a somewhat
1952 smaller binary, but this option is not explicitly supported by the
1953 toolchain and since binutils 2.14 it does not even work at all.
1955 Say Y to use the 64-bit format or N to use the 32-bit one.
1960 bool "Include IRIX binary compatibility"
1961 depends on CPU_BIG_ENDIAN && 32BIT && BROKEN

1964 bool "Kernel support for Linux/MIPS 32-bit binary compatibility"
1967 Select this option if you want Linux/MIPS 32-bit binary
1968 compatibility. Since all software available for Linux/MIPS is
1969 currently 32-bit you should say Y here.
1973 depends on MIPS32_COMPAT
1977 bool "Kernel support for o32 binaries"
1978 depends on MIPS32_COMPAT
1980 Select this option if you want to run o32 binaries. These are pure
1981 32-bit binaries as used by the 32-bit Linux/MIPS port. Most of
1982 existing binaries are in this format.
1987 bool "Kernel support for n32 binaries"
1988 depends on MIPS32_COMPAT
1990 Select this option if you want to run n32 binaries. These are
1991 64-bit binaries using 32-bit quantities for addressing and certain
1992 data that would normally be 64-bit. They are used in special
1999 default y if MIPS32_O32 || MIPS32_N32
2002 bool "Enable seccomp to safely compute untrusted bytecode"
2003 depends on PROC_FS && BROKEN
2006 This kernel feature is useful for number crunching applications
2007 that may need to compute untrusted bytecode during their
2008 execution. By using pipes or other transports made available to
2009 the process as file descriptors supporting the read/write
2010 syscalls, it's possible to isolate those applications in
2011 their own address space using seccomp. Once seccomp is
2012 enabled via /proc/<pid>/seccomp, it cannot be disabled
2013 and the task is only allowed to execute a few safe syscalls
2014 defined by each seccomp mode.
2016 If unsure, say Y. Only embedded should say N here.
2019 bool "Power Management support (EXPERIMENTAL)"
2020 depends on EXPERIMENTAL && SOC_AU1X00
2023 tristate "Advanced Power Management Emulation"
2026 APM is a BIOS specification for saving power using several different
2027 techniques. This is mostly useful for battery powered systems with
2028 APM compliant BIOSes. If you say Y here, the system time will be
2029 reset after a RESUME operation, the /proc/apm device will provide
2030 battery status information, and user-space programs will receive
2031 notification of APM "events" (e.g. battery status change).
2033 In order to use APM, you will need supporting software. For location
2034 and more information, read <file:Documentation/pm.txt> and the
2035 Battery Powered Linux mini-HOWTO, available from
2036 <http://www.tldp.org/docs.html#howto>.
2038 This driver does not spin down disk drives (see the hdparm(8)
2039 manpage ("man 8 hdparm") for that), and it doesn't turn off
2040 VESA-compliant "green" monitors.
2042 Generally, if you don't have a battery in your machine, there isn't
2043 much point in using this driver and you should say N. If you get
2044 random kernel OOPSes or reboots that don't seem to be related to
2045 anything, try disabling/enabling this option (or disabling/enabling
