  38           The Extended Industry Standard Architecture (EISA) bus was
  39           developed as an open alternative to the IBM MicroChannel bus.
  40
  41           The EISA bus provided some of the features of the IBM MicroChannel
  42           bus while maintaining backward compatibility with cards made for
  43           the older ISA bus.  The EISA bus saw limited use between 1988 and
  44           1995 when it was made obsolete by the PCI bus.
  45

  61           Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  62           computer.  These are credit-card size devices such as network cards,
  63           modems or hard drives often used with laptops computers.  There are
  64           actually two varieties of these cards: the older 16 bit PCMCIA cards
  65           and the newer 32 bit CardBus cards.  If you want to use CardBus
  66           cards, you need to say Y here and also to "CardBus support" below.
  67
  68           To use your PC-cards, you will need supporting software from David
  69           Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  70           for location).  Please also read the PCMCIA-HOWTO, available from

 301           This option prevents any floating-point instructions from being

 304           kernel will only be usable on machines without a floating-point
 305           math coprocessor. This makes the kernel a bit faster as no tests

 330           ( = direct memory access) on many Amiga systems, and it is also said
 331           to destabilize other machines. It is very likely that this will
 332           cause serious problems on any Amiga or Atari Medusa if set. The only
 333           configuration where it should work are 68030-based Ataris, where it

 350           The 68060 generally uses copyback caching of recently accessed data.
 351           Copyback caching means that memory writes will be held in an on-chip
 352           cache and only written back to memory some time later.  Saying Y
 353           here will force supervisor (kernel) accesses to use writethrough
 354           caching.  Writethrough caching means that data is written to memory
 355           straight away, so that cache and memory data always agree.
 356           Writethrough caching is less efficient, but is needed for some
 357           drivers on 68060 based systems where the 68060 bus snooping signal
 358           is hardwired on.  The 53c710 SCSI driver is known to suffer from

 633           "console=ttyS1". (Try "man bootparam" or see the documentation of
 634           your boot loader (lilo or loadlin) about how to pass options to the
