5 | SPARC is a family of RISC microprocessors designed and marketed by | |
6 | Sun Microsystems, incorporated. They are very widely found in Sun | |
7 | workstations and clones. | |

495 | Find out whether your system includes a PCI bus. PCI is the name of |
496 | a bus system, i.e. the way the CPU talks to the other stuff inside | |
497 | your box. If you say Y here, the kernel will include drivers and | |
498 | infrastructure code to support PCI bus devices. | |

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

516 | help | |
517 | If you say Y, the OpenPROM device tree will be available as a | |
518 | virtual file system, which you can mount to /proc/openprom by "mount | |
519 | -t openpromfs none /proc/openprom". | |
520 | ||
521 | To compile the /proc/openprom support as a module, choose M here: the | |
522 | module will be called openpromfs. | |
523 | ||
524 | Only choose N if you know in advance that you will not need to modify | |
525 | OpenPROM settings on the running system. | |
