44 If you say N here, the kernel will run on single and multiprocessor
45 machines, but will use only one CPU of a multiprocessor machine. If

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

108 Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
109 computer. These are credit-card size devices such as network cards,
110 modems or hard drives often used with laptops computers. There are
111 actually two varieties of these cards: the older 16 bit PCMCIA cards
112 and the newer 32 bit CardBus cards. If you want to use CardBus
113 cards, you need to say Y here and also to "CardBus support" below.
114
115 To use your PC-cards, you will need supporting software from David
116 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
117 for location). Please also read the PCMCIA-HOWTO, available from
118 <http://www.tldp.org/docs.html#howto>.

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

275 bool "Unix98 PTY support"
276 ---help---
277 A pseudo terminal (PTY) is a software device consisting of two
278 halves: a master and a slave. The slave device behaves identical to
279 a physical terminal; the master device is used by a process to
280 read data from and write data to the slave, thereby emulating a
281 terminal. Typical programs for the master side are telnet servers
282 and xterms.
283
284 Linux has traditionally used the BSD-like names /dev/ptyxx for
285 masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
286 has a number of problems. The GNU C library glibc 2.1 and later,
287 however, supports the Unix98 naming standard: in order to acquire a
288 pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
289 terminal is then made available to the process and the pseudo
290 terminal slave can be accessed as /dev/pts/<number>. What was
291 traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
292
293 The entries in /dev/pts/ are created on the fly by a virtual
294 file system; therefore, if you say Y here you should say Y to
295 "/dev/pts file system for Unix98 PTYs" as well.
296
297 If you want to say Y here, you need to have the C library glibc 2.1
298 or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
299 Read the instructions in <file:Documentation/Changes> pertaining to
300 pseudo terminals. It's safe to say N.
