22 The ARM series is a line of low-power-consumption RISC chip designs
23 licensed by ARM Ltd and targeted at embedded applications and
24 handhelds such as the Compaq IPAQ. ARM-based PCs are no longer
25 manufactured, but legacy ARM-based PC hardware remains popular in

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.

1233 help
1234 kexec is a system call that implements the ability to shutdown your
1235 current kernel, and to start another kernel. It is like a reboot
1236 but it is independent of the system firmware. And like a reboot
1237 you can start any kernel with it, not just Linux.
1238
1239 It is an ongoing process to be certain the hardware in a machine
1240 is properly shutdown, so do not be surprised if this code does not
1241 initially work for you. It may help to enable device hotplugging
1242 support.

1306 This is necessary to run most binaries. Linux does not currently
1307 support floating point hardware so you need to say Y here even if
1308 your machine has an FPA or floating point co-processor podule.

1319 Note that gcc does not generate 80-bit operations by default,
1320 so in most cases this option only enlarges the size of the

1329 Say Y here to include the FAST floating point emulator in the kernel.
1330 This is an experimental much faster emulator which now also has full
1331 precision for the mantissa. It does not support any exceptions.
1332 It is very simple, and approximately 3-6 times faster than NWFPE.
1333
1334 It should be sufficient for most programs. It may be not suitable
1335 for scientific calculations, but you have to check this for yourself.
1336 If you do not feel you need a faster FP emulation you should better
1337 choose NWFPE.
