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

603	  This option allows the default printing mode to be set, and then

606	  For example, if one wanted the option of printing verbose
607	  machine checks, but wanted the default to be as if verbose
608	  machine check printing was turned off, then one would choose
609	  the printing mode to be 0. Then, upon reboot, one could add
610	  the boot command line "verbose_mcheck=1" to get the normal
611	  verbose machine check printing, or "verbose_mcheck=2" to get
612	  the maximum information available.
613

624	---help---
625	  If you enable this option, a subdirectory inside /proc called
626	  /proc/srm_environment will give you access to the all important
627	  SRM environment variables (those which have a name) and also
628	  to all others (by their internal number).
629
630	  SRM is something like a BIOS for Alpha machines. There are some
631	  other such BIOSes, like AlphaBIOS, which this driver cannot
632	  support (hey, that's not SRM!).
633
634	  Despite the fact that this driver doesn't work on all Alphas (but
635	  only on those which have SRM as their firmware), it's save to
636	  build it even if your particular machine doesn't know about SRM
637	  (or if you intend to compile a generic kernel). It will simply
638	  not create those subdirectory in /proc (and give you some warning,
639	  of course).
640
641	  This driver is also available as a module and will be called
642	  srm_env then.
