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

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

651	  Despite the fact that this driver doesn't work on all Alphas (but
652	  only on those which have SRM as their firmware), it's save to
653	  build it even if your particular machine doesn't know about SRM
654	  (or if you intend to compile a generic kernel). It will simply
655	  not create those subdirectory in /proc (and give you some warning,
656	  of course).
657
658	  This driver is also available as a module and will be called
659	  srm_env then.
