  64           The Extended Industry Standard Architecture (EISA) bus was
  65           developed as an open alternative to the IBM MicroChannel bus.
  66
  67           The EISA bus provided some of the features of the IBM MicroChannel
  68           bus while maintaining backward compatibility with cards made for
  69           the older ISA bus.  The EISA bus saw limited use between 1988 and
  70           1995 when it was made obsolete by the PCI bus.

  87           Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  88           computer.  These are credit-card size devices such as network cards,
  89           modems or hard drives often used with laptops computers.  There are
  90           actually two varieties of these cards: the older 16 bit PCMCIA cards
  91           and the newer 32 bit CardBus cards.  If you want to use CardBus
  92           cards, you need to say Y here and also to "CardBus support" below.
  93
  94           To use your PC-cards, you will need supporting software from David
  95           Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>

 357           to destabilize other machines. It is very likely that this will
 358           cause serious problems on any Amiga or Atari Medusa if set. The only
 359           configuration where it should work are 68030-based Ataris, where it

 377           The 68060 generally uses copyback caching of recently accessed data.
 378           Copyback caching means that memory writes will be held in an on-chip
 379           cache and only written back to memory some time later.  Saying Y
 380           here will force supervisor (kernel) accesses to use writethrough
 381           caching.  Writethrough caching means that data is written to memory
 382           straight away, so that cache and memory data always agree.
 383           Writethrough caching is less efficient, but is needed for some
 384           drivers on 68060 based systems where the 68060 bus snooping signal
