499 There are two different types of booting firmware on Alphas: SRM,
500 which is command line driven, and ARC, which uses menus and arrow
501 keys. Details about the Linux/Alpha booting process are contained in
502 the Linux/Alpha FAQ, accessible on the WWW from
503 <http://www.alphalinux.org/>.
504
505 The usual way to load Linux on an Alpha machine is to use MILO
506 (a bootloader that lets you pass command line parameters to the
507 kernel just like lilo does for the x86 architecture) which can be
508 loaded either from ARC or can be installed directly as a permanent
509 firmware replacement from floppy (which requires changing a certain
510 jumper on the motherboard). If you want to do either of these, say N
511 here. If MILO doesn't work on your system (true for Jensen
512 motherboards), you can bypass it altogether and boot Linux directly
513 from an SRM console; say Y here in order to do that. Note that you
514 won't be able to boot from an IDE disk using SRM.
515
516 If unsure, say N.

639 SRM is something like a BIOS for Alpha machines. There are some
640 other such BIOSes, like AlphaBIOS, which this driver cannot
641 support (hey, that's not SRM!).
642
643 Despite the fact that this driver doesn't work on all Alphas (but
644 only on those which have SRM as their firmware), it's save to
645 build it even if your particular machine doesn't know about SRM
646 (or if you intend to compile a generic kernel). It will simply
647 not create those subdirectory in /proc (and give you some warning,
648 of course).
649
650 This driver is also available as a module and will be called
