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

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

632	  SRM environment variables (those which have a name) and also
633	  to all others (by their internal number).

635	  SRM is something like a BIOS for Alpha machines. There are some

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