config EISA
	bool
	---help---
	  The Extended Industry Standard Architecture (EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older ISA bus.  The EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the PCI bus.

	  Say Y here if you are building a kernel for an EISA-based machine.

	  Otherwise, say N.

	  MicroChannel Architecture is found in some IBM PS/2 machines and

	  Say Y to include the NWFPE floating point emulator in the kernel.
	  This is necessary to run most binaries. Linux does not currently
	  support floating point hardware so you need to say Y here even if
	  your machine has an FPA or floating point co-processor podule.

	  You may say N here if you are going to load the Acorn FPEmulator
	  early in the bootup.

	  Note that gcc does not generate 80-bit operations by default,
	  so in most cases this option only enlarges the size of the

	  You almost surely want to say N here.

	  Say Y here to include the FAST floating point emulator in the kernel.
	  This is an experimental much faster emulator which now also has full
	  precision for the mantissa.  It does not support any exceptions.
	  It is very simple, and approximately 3-6 times faster than NWFPE.

	  It should be sufficient for most programs.  It may be not suitable
	  for scientific calculations, but you have to check this for yourself.
	  If you do not feel you need a faster FP emulation you should better
	  choose NWFPE.
