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