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

531 machines, but will use only one CPU of a multiprocessor machine. If
532 you say Y here, the kernel will run on many, but not all,

534 will run faster if you say N here.

584 Process creation and other aspects of virtual memory management can

588 Under normal circumstances, this is so far and above what is needed
589 as to be laughable. However, there are certain applications (such
590 as benchmark-grade in-kernel web serving) that can make use of as

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

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