723 This option enables special console drivers which allow the kernel
724 to print messages very early in the bootup process.
725
726 This is useful for kernel debugging when your machine crashes very
727 early before the console code is initialized. For normal operation,
728 it is not recommended because it looks ugly on some machines and
729 doesn't cooperate with an X server. You should normally say N here,

770 byte order. These modes require different kernels and a different

1811 The PCI-HOWTO, available from
1812 <http://www.tldp.org/docs.html#howto>, contains valuable
1813 information about which PCI hardware does work under Linux and which
1814 doesn't.

1836 The Extended Industry Standard Architecture (EISA) bus was
1837 developed as an open alternative to the IBM MicroChannel bus.
1838
1839 The EISA bus provided some of the features of the IBM MicroChannel
1840 bus while maintaining backward compatibility with cards made for
1841 the older ISA bus. The EISA bus saw limited use between 1988 and
1842 1995 when it was made obsolete by the PCI bus.
1843
1844 Say Y here if you are building a kernel for an EISA-based machine.
1845
1846 Otherwise, say N.

1886 help
1887 A 64-bit kernel is usually built using the 64-bit ELF binary object
1888 format as it's one that allows arbitrary 64-bit constructs. For
1889 kernels that are loaded within the KSEG compatibility segments the
1890 32-bit ELF format can optionally be used resulting in a somewhat
1891 smaller binary, but this option is not explicitly supported by the
1892 toolchain and since binutils 2.14 it does not even work at all.
1893
1894 Say Y to use the 64-bit format or N to use the 32-bit one.

1896 If unsure say Y.
