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.

98 ---help---
99 If you say Y here, it will be possible to use a serial port as the
100 system console (the system console is the device which receives all
101 kernel messages and warnings and which allows logins in single user
102 mode). This could be useful if some terminal or printer is connected
103 to that serial port.
104
105 Even if you say Y here, the currently visible virtual console
106 (/dev/tty0) will still be used as the system console by default, but
107 you can alter that using a kernel command line option such as
108 "console=ttyS1". (Try "man bootparam" or see the documentation of
109 your boot loader (silo) about how to pass options to the kernel at
110 boot time.)
111
112 If you don't have a graphics card installed and you say Y here, the
113 kernel will automatically use the first serial line, /dev/ttyS0, as
114 system console.
115
116 If unsure, say N.

204 cards, you need to say Y here and also to "CardBus support" below.
205
206 To use your PC-cards, you will need supporting software from David
207 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
