- SPARC is a family of RISC microprocessors designed and marketed by
- Sun Microsystems, incorporated. This port covers the newer 64-bit
- UltraSPARC. The UltraLinux project maintains both the SPARC32 and
- SPARC64 ports; its web page is available at

This lets you select the page size of the kernel.
- 8KB and 64KB work quite well, since Sparc ELF sections
+ 8KB and 64KB work quite well, since SPARC ELF sections
provide for up to 64KB alignment.
Therefore, 512KB and 4MB are for expert hackers only.

Say Y here to experiment with turning CPUs off and on. CPUs
can be controlled through /sys/devices/system/cpu/cpu#.
Say N if you want to disable CPU hotplug.
config SMP
bool "Symmetric multi-processing support"
- ---help---
+ help
This enables support for systems with more than one CPU. If you have
a system with only one CPU, 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.
-
- 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 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
- available at <http://www.tldp.org/docs.html#howto>.

config ISA
bool
- help
- Find out whether you have ISA slots on your motherboard. ISA is the
- name of a bus system, i.e. the way the CPU talks to the other stuff
- inside your box. Other bus systems are PCI, EISA, MicroChannel
- (MCA) or VESA. ISA is an older system, now being displaced by PCI;
- newer boards don't support it. If you have ISA, say Y, otherwise N.
config ISAPNP
bool
- help
- Say Y here if you would like support for ISA Plug and Play devices.
- Some information is in <file:Documentation/isapnp.txt>.

- If unsure, say Y.
config EISA
bool
- ---help---
- The Extended Industry Standard Architecture (EISA) bus was
- developed as an open alternative to the IBM MicroChannel bus.
-
- The EISA bus provided some of the features of the IBM MicroChannel
- bus while maintaining backward compatibility with cards made for
- the older ISA bus. The EISA bus saw limited use between 1988 and
- 1995 when it was made obsolete by the PCI bus.
-
- Say Y here if you are building a kernel for an EISA-based machine.
-
- Otherwise, say N.
config MCA
bool
- help
- MicroChannel Architecture is found in some IBM PS/2 machines and
- laptops. It is a bus system similar to PCI or ISA. See
- <file:Documentation/mca.txt> (and especially the web page given
- there) before attempting to build an MCA bus kernel.
config PCMCIA

computer. These are credit-card size devices such as network cards,
modems or hard drives often used with laptops computers. There are
