496 There are two different types of booting firmware on Alphas: SRM,
497 which is command line driven, and ARC, which uses menus and arrow
498 keys. Details about the Linux/Alpha booting process are contained in
499 the Linux/Alpha FAQ, accessible on the WWW from
500 <http://www.alphalinux.org/>.
501
502 The usual way to load Linux on an Alpha machine is to use MILO
503 (a bootloader that lets you pass command line parameters to the
504 kernel just like lilo does for the x86 architecture) which can be
505 loaded either from ARC or can be installed directly as a permanent
506 firmware replacement from floppy (which requires changing a certain
507 jumper on the motherboard). If you want to do either of these, say N
508 here. If MILO doesn't work on your system (true for Jensen
509 motherboards), you can bypass it altogether and boot Linux directly
510 from an SRM console; say Y here in order to do that. Note that you
511 won't be able to boot from an IDE disk using SRM.
512
513 If unsure, say N.

638 other such BIOSes, like AlphaBIOS, which this driver cannot
639 support (hey, that's not SRM!).
640
641 Despite the fact that this driver doesn't work on all Alphas (but
642 only on those which have SRM as their firmware), it's save to
643 build it even if your particular machine doesn't know about SRM
644 (or if you intend to compile a generic kernel). It will simply
645 not create those subdirectory in /proc (and give you some warning,
646 of course).
647
648 This driver is also available as a module and will be called
