  20. SPARC is a family of RISC microprocessors designed and marketed by
  21. Sun Microsystems, incorporated. They are very widely found in Sun
  22. workstations and clones. This port covers the original 32-bit SPARC;
  23. it is old and stable and usually considered one of the "big three"
  24. along with the Intel and Alpha ports. The UltraLinux project
  25. maintains both the SPARC32 and SPARC64 ports; its web page is
  26. available at <http://www.ultralinux.org/>.

  52. ---help---
  53. This enables support for systems with more than one CPU. If you have
  54. a system with only one CPU, say N. If you have a system with more
  55. than one CPU, say Y.
  56. If you say N here, the kernel will run on single and multiprocessor
  57. machines, but will use only one CPU of a multiprocessor machine. If
  58. you say Y here, the kernel will run on many, but not all,
  59. singleprocessor machines. On a singleprocessor machine, the kernel
  60. will run faster if you say N here.
  61. People using multiprocessor machines who say Y here should also say
  62. Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
  63. Management" code will be disabled if you say Y here.
  64. See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
  65. available at <http://www.tldp.org/docs.html#howto>.

  75. bool
  76. default y
  77. ---help---
  78. If you say Y here, it will be possible to use a serial port as the
  79. system console (the system console is the device which receives all
  80. kernel messages and warnings and which allows logins in single user
  81. mode). This could be useful if some terminal or printer is connected
  82. to that serial port.
  83. Even if you say Y here, the currently visible virtual console
  84. (/dev/tty0) will still be used as the system console by default, but
  85. you can alter that using a kernel command line option such as
  86. "console=ttyS1". (Try "man bootparam" or see the documentation of
  87. your boot loader (silo) about how to pass options to the kernel at
  88. boot time.)
  89. If you don't have a graphics card installed and you say Y here, the
  90. kernel will automatically use the first serial line, /dev/ttyS0, as
  91. system console.
  92. If unsure, say N.

  157. Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  158. computer. These are credit-card size devices such as network cards,
  159. modems or hard drives often used with laptops computers. There are
  160. actually two varieties of these cards: the older 16 bit PCMCIA cards
  161. and the newer 32 bit CardBus cards. If you want to use CardBus
  162. cards, you need to say Y here and also to "CardBus support" below.
  163. To use your PC-cards, you will need supporting software from David
  164. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  165. for location). Please also read the PCMCIA-HOWTO, available from
  166. <http://www.tldp.org/docs.html#howto>.

  168. modules will be called pcmcia_core and ds.

  196. To compile the /proc/openprom support as a module, choose M here: the
