  1560. The Extended Industry Standard Architecture (EISA) bus was
  1561. developed as an open alternative to the IBM MicroChannel bus.
  1562. The EISA bus provided some of the features of the IBM MicroChannel
  1563. bus while maintaining backward compatibility with cards made for
  1564. the older ISA bus. The EISA bus saw limited use between 1988 and
  1565. 1995 when it was made obsolete by the PCI bus.
  1566. Say Y here if you are building a kernel for an EISA-based machine.
  1567. Otherwise, say N.

  1596. A 64-bit kernel is usually built using the 64-bit ELF binary object
  1597. format as it's one that allows arbitrary 64-bit constructs. For
  1598. kernels that are loaded within the KSEG compatibility segments the
  1599. 32-bit ELF format can optionally be used resulting in a somewhat
  1600. smaller binary, but this option is not explicitly supported by the
  1601. toolchain and since binutils 2.14 it does not even work at all.
  1602. Say Y to use the 64-bit format or N to use the 32-bit one.
