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

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

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

633	  SRM is something like a BIOS for Alpha machines. There are some
634	  other such BIOSes, like AlphaBIOS, which this driver cannot

636
637	  Despite the fact that this driver doesn't work on all Alphas (but
638	  only on those which have SRM as their firmware), it's save to
639	  build it even if your particular machine doesn't know about SRM
640	  (or if you intend to compile a generic kernel). It will simply
641	  not create those subdirectory in /proc (and give you some warning,
642	  of course).
643
644	  This driver is also available as a module and will be called
645	  srm_env then.
