875 Some MIPS machines can be configured for either little or big endian
876 byte order. These modes require different kernels and a different
877 Linux distribution. In general there is one prefered byteorder for a
878 particular system but some systems are just as commonly used in the

1815 help
1816 Find out whether you have a PCI motherboard. PCI is the name of a
1817 bus system, i.e. the way the CPU talks to the other stuff inside
1818 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
1819 say Y, otherwise N.
1820
1821 The PCI-HOWTO, available from
1822 <http://www.tldp.org/docs.html#howto>, contains valuable
1823 information about which PCI hardware does work under Linux and which
1824 doesn't.

1848 The Extended Industry Standard Architecture (EISA) bus was
1849 developed as an open alternative to the IBM MicroChannel bus.
1850
1851 The EISA bus provided some of the features of the IBM MicroChannel
1852 bus while maintaining backward compatibility with cards made for
1853 the older ISA bus. The EISA bus saw limited use between 1988 and
1854 1995 when it was made obsolete by the PCI bus.
1855
1856 Say Y here if you are building a kernel for an EISA-based machine.
1857
1858 Otherwise, say N.

1899 A 64-bit kernel is usually built using the 64-bit ELF binary object
1900 format as it's one that allows arbitrary 64-bit constructs. For
1901 kernels that are loaded within the KSEG compatibility segments the
1902 32-bit ELF format can optionally be used resulting in a somewhat
1903 smaller binary, but this option is not explicitly supported by the
1904 toolchain and since binutils 2.14 it does not even work at all.

1956 help
1957 This kernel feature is useful for number crunching applications
1958 that may need to compute untrusted bytecode during their
1959 execution. By using pipes or other transports made available to
1960 the process as file descriptors supporting the read/write
1961 syscalls, it's possible to isolate those applications in
1962 their own address space using seccomp. Once seccomp is
1963 enabled via /proc/<pid>/seccomp, it cannot be disabled
1964 and the task is only allowed to execute a few safe syscalls
1965 defined by each seccomp mode.
1966

1976 ---help---
1977 APM is a BIOS specification for saving power using several different
1978 techniques. This is mostly useful for battery powered systems with
1979 APM compliant BIOSes. If you say Y here, the system time will be
1980 reset after a RESUME operation, the /proc/apm device will provide
1981 battery status information, and user-space programs will receive
1982 notification of APM "events" (e.g. battery status change).
1983
1984 In order to use APM, you will need supporting software. For location
1985 and more information, read <file:Documentation/pm.txt> and the
1986 Battery Powered Linux mini-HOWTO, available from
1987 <http://www.tldp.org/docs.html#howto>.
1988
1989 This driver does not spin down disk drives (see the hdparm(8)
1990 manpage ("man 8 hdparm") for that), and it doesn't turn off
1991 VESA-compliant "green" monitors.
1992
1993 Generally, if you don't have a battery in your machine, there isn't
1994 much point in using this driver and you should say N. If you get
1995 random kernel OOPSes or reboots that don't seem to be related to
1996 anything, try disabling/enabling this option (or disabling/enabling
1997 APM in your BIOS).
