  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/>.

  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

  91. ---help---
  92. Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
  93. computer. These are credit-card size devices such as network cards,
  94. modems or hard drives often used with laptops computers. There are
  95. actually two varieties of these cards: the older 16 bit PCMCIA cards
  96. and the newer 32 bit CardBus cards. If you want to use CardBus
  97. cards, you need to say Y here and also to "CardBus support" below.
  98. To use your PC-cards, you will need supporting software from David
  99. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  100. for location). Please also read the PCMCIA-HOWTO, available from
  101. <http://www.tldp.org/docs.html#howto>.
  102. To compile this driver as modules, choose M here: the
  103. modules will be called pcmcia_core and ds.

  113. ---help---
  114. If you say Y here, it will be possible to use a serial port as the
  115. system console (the system console is the device which receives all
  116. kernel messages and warnings and which allows logins in single user
  117. mode). This could be useful if some terminal or printer is connected
  118. to that serial port.
  119. Even if you say Y here, the currently visible virtual console
  120. (/dev/tty0) will still be used as the system console by default, but
  121. you can alter that using a kernel command line option such as
  122. "console=ttyS1". (Try "man bootparam" or see the documentation of
  123. your boot loader (silo) about how to pass options to the kernel at
  124. boot time.)
  125. If you don't have a graphics card installed and you say Y here, the
  126. kernel will automatically use the first serial line, /dev/ttyS0, as
  127. system console.
  128. If unsure, say N.

  183. virtual file system, which you can mount to /proc/openprom by "mount
  184. -t openpromfs none /proc/openprom".
  185. To compile the /proc/openprom support as a module, choose M here: the
  186. module will be called openpromfs.

  188. OpenPROM settings on the running system.
