	  This is Linux's home port.  Linux was originally native to the Intel
	  386, and runs on all the later x86 processors including the Intel
	  486, 586, Pentiums, and various instruction-set-compatible chips by
	  AMD, Cyrix, and others.

config SMP
	bool "Symmetric multi-processing support"
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, like most personal computers, say N. If
	  you have a system with more than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  singleprocessor machines. On a singleprocessor machine, the kernel
	  will run faster if you say N here.

	  Note that if you say Y here and choose architecture "586" or
	  "Pentium" under "Processor family", the kernel will not work on 486
	  architectures. Similarly, multiprocessor kernels for the "PPro"
	  architecture may not work on all Pentium based boards.

	  People using multiprocessor machines who say Y here should also say
	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
	  Management" code will be disabled if you say Y here.

	  See also the <file:Documentation/smp.txt>,
	  <file:Documentation/i386/IO-APIC.txt>,
	  <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at
	  <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

config X86_PC
	bool "PC-compatible"
	help
	  Choose this option if your computer is a standard PC or compatible.

config X86_ELAN
	bool "AMD Elan"
	help
	  Select this for an AMD Elan processor.

	  Do not use this option for K6/Athlon/Opteron processors!

	  If unsure, choose "PC-compatible" instead.

config X86_VOYAGER
	bool "Voyager (NCR)"
	help
	  Voyager is an MCA-based 32-way capable SMP architecture proprietary
	  to NCR Corp.  Machine classes 345x/35xx/4100/51xx are Voyager-based.

	  *** WARNING ***

	  If you do not specifically know you have a Voyager based machine,
	  say N here, otherwise the kernel you build will not be bootable.

config X86_NUMAQ
	bool "NUMAQ (IBM/Sequent)"
	select SMP
	select NUMA
	help
	  This option is used for getting Linux to run on a (IBM/Sequent) NUMA
	  multiquad box. This changes the way that processors are bootstrapped,
	  and uses Clustered Logical APIC addressing mode instead of Flat Logical.
	  You will need a new lynxer.elf file to flash your firmware with - send
	  email to <Martin.Bligh@us.ibm.com>.

config X86_SUMMIT
	bool "Summit/EXA (IBM x440)"
	depends on SMP
	help
	  This option is needed for IBM systems that use the Summit/EXA chipset.
	  In particular, it is needed for the x440.

	  If you don't have one of these computers, you should say N here.
	  If you want to build a NUMA kernel, you must select ACPI.

config X86_BIGSMP
	bool "Support for other sub-arch SMP systems with more than 8 CPUs"
	depends on SMP
	help
	  This option is needed for the systems that have more than 8 CPUs
	  and if the system is not of any sub-arch type above.

	  If you don't have such a system, you should say N here.

config X86_VISWS
	bool "SGI 320/540 (Visual Workstation)"
	help
	  The SGI Visual Workstation series is an IA32-based workstation
	  based on SGI systems chips with some legacy PC hardware attached.

	  Say Y here to create a kernel to run on the SGI 320 or 540.

	  A kernel compiled for the Visual Workstation will not run on PCs
	  and vice versa. See <file:Documentation/sgi-visws.txt> for details.

config X86_GENERICARCH
       bool "Generic architecture (Summit, bigsmp, ES7000, default)"
       help
          This option compiles in the Summit, bigsmp, ES7000, default subarchitectures.
	  It is intended for a generic binary kernel.
	  If you want a NUMA kernel, select ACPI.   We need SRAT for NUMA.

config X86_ES7000
	bool "Support for Unisys ES7000 IA32 series"
	depends on SMP
	help
	  Support for Unisys ES7000 systems.  Say 'Y' here if this kernel is
	  supposed to run on an IA32-based Unisys ES7000 system.
	  Only cho
