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
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.
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.
81 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO

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
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

154 is emulated, and therefore it is not completely atomic.

166 This driver toggles the front-panel LED on sun4m systems
167 in a user-specifiable manner. Its state can be probed
168 by reading /proc/led and its blinking mode can be changed
169 via writes to /proc/led

199 Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
200 computer. These are credit-card size devices such as network cards,
201 modems or hard drives often used with laptops computers. There are
202 actually two varieties of these cards: the older 16 bit PCMCIA cards
203 and the newer 32 bit CardBus cards. If you want to use CardBus
204 cards, you need to say Y here and also to "CardBus support" below.
206 To use your PC-cards, you will need supporting software from David
207 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
208 for location). Please also read the PCMCIA-HOWTO, available from
209 <http://www.tldp.org/docs.html#howto>.
211 To compile this driver as modules, choose M here: the
212 modules will be called pcmcia_core and ds.

233 CONFIG_PCI is needed for all JavaStation's (including MrCoffee),
234 CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC.
235 All of these platforms are extremely obscure, so say N if unsure.

245 If you say Y, the OpenPROM device tree will be available as a
246 virtual file system, which you can mount to /proc/openprom by "mount
247 -t openpromfs none /proc/openprom".
249 To compile the /proc/openprom support as a module, choose M here: the
250 module will be called openpromfs.
252 Only choose N if you know in advance that you will not need to modify
253 OpenPROM settings on the running system.
