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

| config SMP |
| bool "Symmetric multi-processing support (does not work on sun4/sun4c)" |
| ---help--- |
| This enables support for systems with more than one CPU. If you have |
| a system with only one CPU, say N. If you have a system with more |
| than one CPU, say Y. |
| |
| If you say N here, the kernel will run on single and multiprocessor |
| machines, but will use only one CPU of a multiprocessor machine. If |
| you say Y here, the kernel will run on many, but not all, |
| singleprocessor machines. On a singleprocessor machine, the kernel |
| will run faster if you say N here. |
| |
| People using multiprocessor machines who say Y here should also say |
| Y to "Enhanced Real Time Clock Support", below. The "Advanced Power |
| Management" code will be disabled if you say Y here. |
| |
| See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO |
| available at <http://www.tldp.org/docs.html#howto>. |

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

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

| CP-1200, JavaEngine-1, Corona, Red October, and Serengeti SGSC. |
| All of these platforms are extremely obscure, so say N if unsure. |

| If you say Y, the OpenPROM device tree will be available as a |
| virtual file system, which you can mount to /proc/openprom by "mount |
| -t openpromfs none /proc/openprom". |
| |
| To compile the /proc/openprom support as a module, choose M here: the |
| module will be called openpromfs. |

| Only choose N if you know in advance that you will not need to modify |
| OpenPROM settings on the running system. |
