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

633	  If you enable this option, a subdirectory inside /proc called

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