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

640	  build it even if your particular machine doesn't know about SRM
641	  (or if you intend to compile a generic kernel). It will simply
642	  not create those subdirectory in /proc (and give you some warning,
