  1563. The Extended Industry Standard Architecture (EISA) bus was
  1564. developed as an open alternative to the IBM MicroChannel bus.
  1565. The EISA bus provided some of the features of the IBM MicroChannel
  1566. bus while maintaining backward compatibility with cards made for
  1567. the older ISA bus. The EISA bus saw limited use between 1988 and
  1568. 1995 when it was made obsolete by the PCI bus.
  1569. Say Y here if you are building a kernel for an EISA-based machine.
  1570. Otherwise, say N.

  1599. A 64-bit kernel is usually built using the 64-bit ELF binary object
  1600. format as it's one that allows arbitrary 64-bit constructs. For
  1601. kernels that are loaded within the KSEG compatibility segments the
  1602. 32-bit ELF format can optionally be used resulting in a somewhat
  1603. smaller binary, but this option is not explicitly supported by the
  1604. toolchain and since binutils 2.14 it does not even work at all.
  1605. Say Y to use the 64-bit format or N to use the 32-bit one.
