  75           run on any supported Alpha system. However, if you configure a
  76           kernel for your specific system, it will be faster and smaller.

 484           There are two different types of booting firmware on Alphas: SRM,
 485           which is command line driven, and ARC, which uses menus and arrow
 486           keys. Details about the Linux/Alpha booting process are contained in
 487           the Linux/Alpha FAQ, accessible on the WWW from
 488           <http://www.alphalinux.org/>.
 489
 490           The usual way to load Linux on an Alpha machine is to use MILO
 491           (a bootloader that lets you pass command line parameters to the
 492           kernel just like lilo does for the x86 architecture) which can be
 493           loaded either from ARC or can be installed directly as a permanent
 494           firmware replacement from floppy (which requires changing a certain
 495           jumper on the motherboard). If you want to do either of these, say N
 496           here. If MILO doesn't work on your system (true for Jensen
 497           motherboards), you can bypass it altogether and boot Linux directly
 498           from an SRM console; say Y here in order to do that. Note that you
 499           won't be able to boot from an IDE disk using SRM.
 500
 501           If unsure, say N.

 515           This enables support for systems with more than one CPU. If you have

 517           you have a system with more than one CPU, say Y.
 518
 519           If you say N here, the kernel will run on single and multiprocessor
 520           machines, but will use only one CPU of a multiprocessor machine. If
 521           you say Y here, the kernel will run on many, but not all,
 522           singleprocessor machines. On a singleprocessor machine, the kernel
 523           will run faster if you say N here.

 594           the printing mode to be 0. Then, upon reboot, one could add

 613           to all others (by their internal number).
 614
 615           SRM is something like a BIOS for Alpha machines. There are some
 616           other such BIOSes, like AlphaBIOS, which this driver cannot
 617           support (hey, that's not SRM!).
 618
 619           Despite the fact that this driver doesn't work on all Alphas (but
 620           only on those which have SRM as their firmware), it's save to
 621           build it even if your particular machine doesn't know about SRM
 622           (or if you intend to compile a generic kernel). It will simply
 623           not create those subdirectory in /proc (and give you some warning,
 624           of course).
 625
 626           This driver is also available as a module and will be called
 627           srm_env then.
