458 | There are two different types of booting firmware on Alphas: SRM, | |
459 | which is command line driven, and ARC, which uses menus and arrow | |

461 | the Linux/Alpha FAQ, accessible on the WWW from | |
462 | <http://www.alphalinux.org/>. | |
463 | ||
464 | The usual way to load Linux on an Alpha machine is to use MILO | |
465 | (a bootloader that lets you pass command line parameters to the | |
466 | kernel just like lilo does for the x86 architecture) which can be | |
467 | loaded either from ARC or can be installed directly as a permanent | |
468 | firmware replacement from floppy (which requires changing a certain | |
469 | jumper on the motherboard). If you want to do either of these, say N | |

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

562 | machine check printing was turned off, then one would choose | |
563 | the printing mode to be 0. Then, upon reboot, one could add | |
564 | the boot command line "verbose_mcheck=1" to get the normal | |
565 | verbose machine check printing, or "verbose_mcheck=2" to get | |
566 | the maximum information available. | |

578 | ---help--- | |
579 | If you enable this option, a subdirectory inside /proc called | |

581 | SRM environment variables (those which have a name) and also | |
582 | to all others (by their internal number). | |

584 | SRM is something like a BIOS for Alpha machines. There are some | |
585 | other such BIOSes, like AlphaBIOS, which this driver cannot | |
586 | support (hey, that's not SRM!). | |
587 | ||
588 | Despite the fact that this driver doesn't work on all Alphas (but | |
589 | only on those which have SRM as their firmware), it's save to | |
590 | build it even if your particular machine doesn't know about SRM | |
591 | (or if you intend to compile a generic kernel). It will simply | |
592 | not create those subdirectory in /proc (and give you some warning, | |
593 | of course). | |
594 | ||
595 | This driver is also available as a module and will be called | |
596 | srm_env then. | |
