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.

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.

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.
