  390. help
  391. kexec is a system call that implements the ability to shutdown your
  392. current kernel, and to start another kernel. It is like a reboot
  393. but it is independent of the system firmware. And like a reboot
  394. you can start any kernel with it, not just Linux.
  395. The name comes from the similarity to the exec system call.
  396. It is an ongoing process to be certain the hardware in a machine
  397. is properly shutdown, so do not be surprised if this code does not
  398. initially work for you. It may help to enable device hotplugging
  399. support. As of this writing the exact hardware interface is
  400. strongly in flux, so no good recommendation can be made.
  401. config SMP
  402. bool "Symmetric multi-processing support"
  403. ---help---
  404. This enables support for systems with more than one CPU. If you have
  405. a system with only one CPU, like most personal computers, say N. If
  406. you have a system with more than one CPU, say Y.
  407. If you say N here, the kernel will run on single and multiprocessor
  408. machines, but will use only one CPU of a multiprocessor machine. If
  409. you say Y here, the kernel will run on many, but not all,
  410. singleprocessor machines. On a singleprocessor machine, the kernel
  411. will run faster if you say N here.
  412. People using multiprocessor machines who say Y here should also say
  413. Y to "Enhanced Real Time Clock Support", below.

  425. kernel will support. The maximum supported value is 32 and the
  426. minimum value which makes sense is 2.

  462. Selecting this option will wakeup the User Break Controller (UBC) on
  463. startup. Although the UBC is left in an awake state when the processor
  464. comes up, some boot loaders misbehave by putting the UBC to sleep in a

  486. Find out whether you have ISA slots on your motherboard. ISA is the

  488. inside your box. Other bus systems are PCI, EISA, MicroChannel
  489. (MCA) or VESA. ISA is an older system, now being displaced by PCI;

  494. The Extended Industry Standard Architecture (EISA) bus was

  497. bus while maintaining backward compatibility with cards made for
