  70           The Extended Industry Standard Architecture (EISA) bus was
  71           developed as an open alternative to the IBM MicroChannel bus.
  72
  73           The EISA bus provided some of the features of the IBM MicroChannel
  74           bus while maintaining backward compatibility with cards made for
  75           the older ISA bus.  The EISA bus saw limited use between 1988 and
  76           1995 when it was made obsolete by the PCI bus.
  77

  94           computer.  These are credit-card size devices such as network cards,
  95           modems or hard drives often used with laptops computers.  There are
  96           actually two varieties of these cards: the older 16 bit PCMCIA cards
  97           and the newer 32 bit CardBus cards.  If you want to use CardBus
  98           cards, you need to say Y here and also to "CardBus support" below.
  99
 100           To use your PC-cards, you will need supporting software from David
 101           Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
 102           for location).  Please also read the PCMCIA-HOWTO, available from

 195           of workstations. Support for these machines is still somewhat
 196           experimental. If you plan to try to use the kernel on such a machine

 312           This option prevents any floating-point instructions from being

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

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

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

 593           If you say Y here, it will be possible to use a serial port as the
 594           system console (the system console is the device which receives all
 595           kernel messages and warnings and which allows logins in single user
 596           mode). This could be useful if some terminal or printer is connected
 597           to that serial port.
 598
 599           Even if you say Y here, the currently visible virtual console
 600           (/dev/tty0) will still be used as the system console by default, but
 601           you can alter that using a kernel command line option such as
 602           "console=ttyS1". (Try "man bootparam" or see the documentation of
 603           your boot loader (lilo or loadlin) about how to pass options to the
 604           kernel at boot time.)
 605
 606           If you don't have a VGA card installed and you say Y here, the
 607           kernel will automatically use the first serial line, /dev/ttyS0, as
 608           system console.
