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