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

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

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

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

 300           This option prevents any floating-point instructions from being

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

 311           This gives you access to some advanced options for the CPU. The

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

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

 394           This enables support for using (parts of) ST-RAM as swap space,
 395           instead of as normal system memory. This can first enhance system
 396           performance if you have lots of alternate RAM (compared to the size
 397           of ST-RAM), because executable code always will reside in faster
 398           memory. ST-RAM will remain as ultra-fast swap space. On the other
 399           hand, it allows much improved dynamic allocations of ST-RAM buffers
 400           for device driver modules (e.g. floppy, ACSI, SLM printer, DMA
 401           sound). The probability that such allocations at module load time
 402           fail is drastically reduced.
