| 460 | keys. Details about the Linux/Alpha booting process are contained in |
| 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 |
| 470 | here. If MILO doesn't work on your system (true for Jensen |
| 471 | motherboards), you can bypass it altogether and boot Linux directly |
| 472 | from an SRM console; say Y here in order to do that. Note that you |
| 473 | won't be able to boot from an IDE disk using SRM. |
| 474 | |
| 475 | If unsure, say N. |

| 477 | config EISA |

| 479 | depends on ALPHA_GENERIC || ALPHA_JENSEN || ALPHA_ALCOR || ALPHA_MIKASA || ALPHA_SABLE || ALPHA_LYNX || ALPHA_NORITAKE || ALPHA_RAWHIDE |

| 484 | depends on ALPHA_SABLE || ALPHA_LYNX || ALPHA_RAWHIDE || ALPHA_DP264 || ALPHA_WILDFIRE || ALPHA_TITAN || ALPHA_GENERIC || ALPHA_SHARK || ALPHA_MARVEL |
| 485 | ---help--- |
| 486 | This enables support for systems with more than one CPU. If you have |
| 487 | a system with only one CPU, like most personal computers, say N. If |
| 488 | you have a system with more than one CPU, say Y. |
| 489 | |
| 490 | If you say N here, the kernel will run on single and multiprocessor |
| 491 | machines, but will use only one CPU of a multiprocessor machine. If |
| 492 | you say Y here, the kernel will run on many, but not all, |
| 493 | singleprocessor machines. On a singleprocessor machine, the kernel |
| 494 | will run faster if you say N here. |

| 497 | available at <http://www.tldp.org/docs.html#howto>. |

| 528 | Access). This option is for configuring high-end multiprocessor |

| 531 | # LARGE_VMALLOC is racy, if you *really* need it then fix it first |
| 532 | config ALPHA_LARGE_VMALLOC |
| 533 | bool |
| 534 | ---help--- |
| 535 | Process creation and other aspects of virtual memory management can |
| 536 | be streamlined if we restrict the kernel to one PGD for all vmalloc |
| 537 | allocations. This equates to about 8GB. |
| 538 | |
| 539 | Under normal circumstances, this is so far and above what is needed |
| 540 | as to be laughable. However, there are certain applications (such |
| 541 | as benchmark-grade in-kernel web serving) that can make use of as |
| 542 | much vmalloc space as is available. |
| 543 | |
| 544 | Say N unless you know you need gobs and gobs of vmalloc space. |

| 553 | ---help--- |
| 554 | This option allows the default printing mode to be set, and then |
| 555 | possibly overridden by a boot command argument. |
| 556 | |
| 557 | For example, if one wanted the option of printing verbose |
| 558 | machine checks, but wanted the default to be as if verbose |
| 559 | machine check printing was turned off, then one would choose |
| 560 | the printing mode to be 0. Then, upon reboot, one could add |
| 561 | the boot command line "verbose_mcheck=1" to get the normal |
| 562 | verbose machine check printing, or "verbose_mcheck=2" to get |
| 563 | the maximum information available. |
| 564 | |
| 565 | Take the default (1) unless you want more control or more info. |

| 575 | ---help--- |
| 576 | If you enable this option, a subdirectory inside /proc called |
| 577 | /proc/srm_environment will give you access to the all important |
| 578 | SRM environment variables (those which have a name) and also |
| 579 | to all others (by their internal number). |
| 580 | |
| 581 | SRM is something like a BIOS for Alpha machines. There are some |
| 582 | other such BIOSes, like AlphaBIOS, which this driver cannot |
| 583 | support (hey, that's not SRM!). |
| 584 | |
| 585 | Despite the fact that this driver doesn't work on all Alphas (but |
| 586 | only on those which have SRM as their firmware), it's save to |
| 587 | build it even if your particular machine doesn't know about SRM |
| 588 | (or if you intend to compile a generic kernel). It will simply |
| 589 | not create those subdirectory in /proc (and give you some warning, |
| 590 | of course). |
| 591 | |
| 592 | This driver is also available as a module and will be called |
| 593 | srm_env then. |
