  59           The Extended Industry Standard Architecture (EISA) bus was
  60           developed as an open alternative to the IBM MicroChannel bus.
  61
  62           The EISA bus provided some of the features of the IBM MicroChannel
  63           bus while maintaining backward compatibility with cards made for
  64           the older ISA bus.  The EISA bus saw limited use between 1988 and
  65           1995 when it was made obsolete by the PCI bus.

1295           This is necessary to run most binaries. Linux does not currently
1296           support floating point hardware so you need to say Y here even if
1297           your machine has an FPA or floating point co-processor podule.
1298
1299           You may say N here if you are going to load the Acorn FPEmulator

1307           emulator.  Otherwise, only 32 and 64-bit support is compiled in.
1308           Note that gcc does not generate 80-bit operations by default,
1309           so in most cases this option only enlarges the size of the
1310           floating point emulator without any good reason.

1318           Say Y here to include the FAST floating point emulator in the kernel.
1319           This is an experimental much faster emulator which now also has full
1320           precision for the mantissa.  It does not support any exceptions.
1321           It is very simple, and approximately 3-6 times faster than NWFPE.
1322
1323           It should be sufficient for most programs.  It may be not suitable
1324           for scientific calculations, but you have to check this for yourself.
1325           If you do not feel you need a faster FP emulation you should better
1326           choose NWFPE.
