490 | ---help--- | |
491 | There are two different types of booting firmware on Alphas: SRM, | |
492 | which is command line driven, and ARC, which uses menus and arrow | |
493 | keys. Details about the Linux/Alpha booting process are contained in | |
494 | the Linux/Alpha FAQ, accessible on the WWW from | |
495 | <http://www.alphalinux.org/>. | |
496 | ||
497 | The usual way to load Linux on an Alpha machine is to use MILO | |
498 | (a bootloader that lets you pass command line parameters to the | |
499 | kernel just like lilo does for the x86 architecture) which can be | |
500 | loaded either from ARC or can be installed directly as a permanent | |
501 | firmware replacement from floppy (which requires changing a certain | |
502 | jumper on the motherboard). If you want to do either of these, say N | |
503 | here. If MILO doesn't work on your system (true for Jensen | |
504 | motherboards), you can bypass it altogether and boot Linux directly | |
505 | from an SRM console; say Y here in order to do that. Note that you | |
506 | won't be able to boot from an IDE disk using SRM. | |
507 | ||
508 | If unsure, say N. | |

523 | This enables support for systems with more than one CPU. If you have | |

526 | ||
527 | If you say N here, the kernel will run on single and multiprocessor | |
528 | machines, but will use only one CPU of a multiprocessor machine. If | |
529 | you say Y here, the kernel will run on many, but not all, | |
530 | singleprocessor machines. On a singleprocessor machine, the kernel | |
531 | will run faster if you say N here. | |

581 | Process creation and other aspects of virtual memory management can | |

605 | machine check printing was turned off, then one would choose | |
606 | the printing mode to be 0. Then, upon reboot, one could add | |
607 | the boot command line "verbose_mcheck=1" to get the normal | |
608 | verbose machine check printing, or "verbose_mcheck=2" to get | |
609 | the maximum information available. | |

636 | Despite the fact that this driver doesn't work on all Alphas (but | |
637 | only on those which have SRM as their firmware), it's save to | |
638 | build it even if your particular machine doesn't know about SRM | |
639 | (or if you intend to compile a generic kernel). It will simply | |
640 | not create those subdirectory in /proc (and give you some warning, | |
641 | of course). | |
642 | ||
