Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 494 | There are two different types of booting firmware on Alphas: SRM, |

| 496 | keys. Details about the Linux/Alpha booting process are contained in |
| 497 | the Linux/Alpha FAQ, accessible on the WWW from |
| 498 | <http://www.alphalinux.org/>. |
| 499 | |
| 500 | The usual way to load Linux on an Alpha machine is to use MILO |
| 501 | (a bootloader that lets you pass command line parameters to the |
| 502 | kernel just like lilo does for the x86 architecture) which can be |
| 503 | loaded either from ARC or can be installed directly as a permanent |
| 504 | firmware replacement from floppy (which requires changing a certain |
| 505 | jumper on the motherboard). If you want to do either of these, say N |
| 506 | here. If MILO doesn't work on your system (true for Jensen |
| 507 | motherboards), you can bypass it altogether and boot Linux directly |
| 508 | from an SRM console; say Y here in order to do that. Note that you |
| 509 | won't be able to boot from an IDE disk using SRM. |

| 618 | minimizes latency, whereas a low frequency minimizes overhead of |
| 619 | process accounting. The later effect is especially significant |
| 620 | when being run under QEMU. |
| 621 | |
| 622 | Note that some Alpha hardware cannot change the interrupt frequency |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 652 | If you enable this option, a subdirectory inside /proc called |
| 653 | /proc/srm_environment will give you access to the all important |
| 654 | SRM environment variables (those which have a name) and also |
| 655 | to all others (by their internal number). |
| 656 | |
| 657 | SRM is something like a BIOS for Alpha machines. There are some |
| 658 | other such BIOSes, like AlphaBIOS, which this driver cannot |
| 659 | support (hey, that's not SRM!). |
| 660 | |
| 661 | Despite the fact that this driver doesn't work on all Alphas (but |
| 662 | only on those which have SRM as their firmware), it's save to |
| 663 | build it even if your particular machine doesn't know about SRM |
| 664 | (or if you intend to compile a generic kernel). It will simply |
| 665 | not create those subdirectory in /proc (and give you some warning, |
| 666 | of course). |
| 667 | |
| 668 | This driver is also available as a module and will be called |
| 669 | srm_env then. |
