510 | There are two different types of booting firmware on Alphas: SRM, | |
511 | which is command line driven, and ARC, which uses menus and arrow | |
512 | keys. Details about the Linux/Alpha booting process are contained in | |
513 | the Linux/Alpha FAQ, accessible on the WWW from | |
514 | <http://www.alphalinux.org/>. | |
515 | ||
516 | The usual way to load Linux on an Alpha machine is to use MILO | |
517 | (a bootloader that lets you pass command line parameters to the | |
518 | kernel just like lilo does for the x86 architecture) which can be | |
519 | loaded either from ARC or can be installed directly as a permanent | |
520 | firmware replacement from floppy (which requires changing a certain | |
521 | jumper on the motherboard). If you want to do either of these, say N | |
522 | here. If MILO doesn't work on your system (true for Jensen | |
523 | motherboards), you can bypass it altogether and boot Linux directly | |
524 | from an SRM console; say Y here in order to do that. Note that you | |
525 | won't be able to boot from an IDE disk using SRM. | |

658 | (or if you intend to compile a generic kernel). It will simply | |
