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

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