  42           The Extended Industry Standard Architecture (EISA) bus was
  43           developed as an open alternative to the IBM MicroChannel bus.
  44
  45           The EISA bus provided some of the features of the IBM MicroChannel
  46           bus while maintaining backward compatibility with cards made for
  47           the older ISA bus.  The EISA bus saw limited use between 1988 and
  48           1995 when it was made obsolete by the PCI bus.
  49

  65           Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  66           computer.  These are credit-card size devices such as network cards,
  67           modems or hard drives often used with laptops computers.  There are
  68           actually two varieties of these cards: the older 16 bit PCMCIA cards
  69           and the newer 32 bit CardBus cards.  If you want to use CardBus
  70           cards, you need to say Y here and also to "CardBus support" below.
  71
  72           To use your PC-cards, you will need supporting software from David
  73           Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  74           for location).  Please also read the PCMCIA-HOWTO, available from

 121           Find out whether you have a PCI motherboard. PCI is the name of a
 122           bus system, i.e. the way the CPU talks to the other stuff inside
 123           your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
 124           VESA. If you have PCI, say Y, otherwise N.

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

 305           This option prevents any floating-point instructions from being
 306           compiled into the kernel, thereby the kernel doesn't save any
 307           floating point context anymore during task switches, so this
 308           kernel will only be usable on machines without a floating-point
 309           math coprocessor. This makes the kernel a bit faster as no tests

 331           This allows to use certain instructions that work with indivisible

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

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

 395           Some Atari 68k machines (including the 520STF and 1020STE) divide
 396           their addressable memory into ST and TT sections.  The TT section
 397           (up to 512MB) is the main memory; the ST section (up to 4MB) is
 398           accessible to the built-in graphics board, runs slower, and is
 399           present mainly for backward compatibility with older machines.
 400
 401           This enables support for using (parts of) ST-RAM as swap space,
 402           instead of as normal system memory. This can first enhance system
 403           performance if you have lots of alternate RAM (compared to the size
 404           of ST-RAM), because executable code always will reside in faster
 405           memory. ST-RAM will remain as ultra-fast swap space. On the other
 406           hand, it allows much improved dynamic allocations of ST-RAM buffers
 407           for device driver modules (e.g. floppy, ACSI, SLM printer, DMA
 408           sound). The probability that such allocations at module load time
 409           fail is drastically reduced.
