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

67 | This enables support for systems with more than one CPU. If you have | |
68 | a system with only one CPU, say N. If you have a system with more | |
69 | than one CPU, say Y. | |
70 | ||
71 | If you say N here, the kernel will run on single and multiprocessor | |
72 | machines, but will use only one CPU of a multiprocessor machine. If | |
73 | you say Y here, the kernel will run on many, but not all, | |
74 | singleprocessor machines. On a singleprocessor machine, the kernel | |
75 | will run faster if you say N here. | |
76 | ||
77 | People using multiprocessor machines who say Y here should also say | |
78 | Y to "Enhanced Real Time Clock Support", below. The "Advanced Power | |
79 | Management" code will be disabled if you say Y here. | |

115 | ---help--- | |
116 | Say Y here if you want to attach PCMCIA- or PC-cards to your Linux | |
117 | computer. These are credit-card size devices such as network cards, | |
118 | modems or hard drives often used with laptops computers. There are | |
119 | actually two varieties of these cards: the older 16 bit PCMCIA cards | |
120 | and the newer 32 bit CardBus cards. If you want to use CardBus | |
121 | cards, you need to say Y here and also to "CardBus support" below. | |
122 | ||
123 | To use your PC-cards, you will need supporting software from David | |
124 | Hinds' pcmcia-cs package (see the file <file:Documentation/Changes> | |
125 | for location). Please also read the PCMCIA-HOWTO, available from | |
126 | <http://www.tldp.org/docs.html#howto>. | |
127 | ||
128 | To compile this driver as modules, choose M here: the | |
129 | modules will be called pcmcia_core and ds. | |

140 | bool | |
141 | default y | |
142 | ---help--- | |
143 | If you say Y here, it will be possible to use a serial port as the | |
144 | system console (the system console is the device which receives all | |
145 | kernel messages and warnings and which allows logins in single user | |
146 | mode). This could be useful if some terminal or printer is connected | |
147 | to that serial port. | |
148 | ||
149 | Even if you say Y here, the currently visible virtual console | |
150 | (/dev/tty0) will still be used as the system console by default, but | |
151 | you can alter that using a kernel command line option such as | |
152 | "console=ttyS1". (Try "man bootparam" or see the documentation of | |
153 | your boot loader (silo) about how to pass options to the kernel at | |
154 | boot time.) | |
155 | ||
156 | If you don't have a graphics card installed and you say Y here, the | |
157 | kernel will automatically use the first serial line, /dev/ttyS0, as | |
158 | system console. | |
159 | ||
160 | If unsure, say N. | |
