460 Use the power-on LED on your machine as a load meter. The exact
461 behavior is platform-dependent, but normally the flash frequency is
462 a hyperbolic function of the 5-minute load average.

476 help
477 kexec is a system call that implements the ability to shutdown your
478 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400479 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800480 you can start any kernel with it, not just Linux.
481
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400482 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800483
484 It is an ongoing process to be certain the hardware in a machine
485 is properly shutdown, so do not be surprised if this code does not
486 initially work for you. It may help to enable device hotplugging
487 support. As of this writing the exact hardware interface is
488 strongly in flux, so no good recommendation can be made.

495 bool "Symmetric multi-processing support"
496 ---help---
497 This enables support for systems with more than one CPU. If you have
498 a system with only one CPU, like most personal computers, say N. If
499 you have a system with more than one CPU, say Y.
500
501 If you say N here, the kernel will run on single and multiprocessor
502 machines, but will use only one CPU of a multiprocessor machine. If
503 you say Y here, the kernel will run on many, but not all,
504 singleprocessor machines. On a singleprocessor machine, the kernel
505 will run faster if you say N here.
506
507 People using multiprocessor machines who say Y here should also say
508 Y to "Enhanced Real Time Clock Support", below.

568 Selecting this option will wakeup the User Break Controller (UBC) on

570 comes up, some boot loaders misbehave by putting the UBC to sleep in a

599 name of a bus system, i.e. the way the CPU talks to the other stuff
600 inside your box. Other bus systems are PCI, EISA, MicroChannel

611 bus while maintaining backward compatibility with cards made for
612 the older ISA bus. The EISA bus saw limited use between 1988 and
613 1995 when it was made obsolete by the PCI bus.
