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