1da177e4 24 handhelds such as the Compaq IPAQ. ARM-based PCs are no longer
f6c8965a 25 manufactured, but legacy ARM-based PC hardware remains popular in

63 The Extended Industry Standard Architecture (EISA) bus was
64 developed as an open alternative to the IBM MicroChannel bus.
65
66 The EISA bus provided some of the features of the IBM MicroChannel
67 bus while maintaining backward compatibility with cards made for
68 the older ISA bus. The EISA bus saw limited use between 1988 and
69 1995 when it was made obsolete by the PCI bus.

1065 This is necessary to run most binaries. Linux does not currently
1066 support floating point hardware so you need to say Y here even if
1067 your machine has an FPA or floating point co-processor podule.

1070 early in the bootup.

1076 Say Y to include 80-bit support in the kernel floating-point
1077 emulator. Otherwise, only 32 and 64-bit support is compiled in.
1078 Note that gcc does not generate 80-bit operations by default,
1079 so in most cases this option only enlarges the size of the
1080 floating point emulator without any good reason.

1088 Say Y here to include the FAST floating point emulator in the kernel.
1089 This is an experimental much faster emulator which now also has full
1090 precision for the mantissa. It does not support any exceptions.
1091 It is very simple, and approximately 3-6 times faster than NWFPE.
1092
1093 It should be sufficient for most programs. It may be not suitable
1094 for scientific calculations, but you have to check this for yourself.
1095 If you do not feel you need a faster FP emulation you should better
1096 choose NWFPE.
