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.
