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

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