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