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/>.
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.

526 This enables support for systems with more than one CPU. If you have
527 a system with only one CPU, like most personal computers, say N. If
528 you have a system with more than one CPU, say Y.
530 If you say N here, the kernel will run on single and multiprocessor
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,
533 singleprocessor machines. On a singleprocessor machine, the kernel
534 will run faster if you say N here.
536 See also the SMP-HOWTO available at

568 depends on DISCONTIGMEM && BROKEN

585 allocations. This equates to about 8GB.
587 Under normal circumstances, this is so far and above what is needed
588 as to be laughable. However, there are certain applications (such
589 as benchmark-grade in-kernel web serving) that can make use of as
590 much vmalloc space as is available.

599 depends on VERBOSE_MCHECK
602 This option allows the default printing mode to be set, and then
603 possibly overridden by a boot command argument.
605 For example, if one wanted the option of printing verbose
606 machine checks, but wanted the default to be as if verbose
607 machine check printing was turned off, then one would choose
608 the printing mode to be 0. Then, upon reboot, one could add
609 the boot command line "verbose_mcheck=1" to get the normal
610 verbose machine check printing, or "verbose_mcheck=2" to get
611 the maximum information available.
613 Take the default (1) unless you want more control or more info.

629 If you enable this option, a subdirectory inside /proc called
630 /proc/srm_environment will give you access to the all important
631 SRM environment variables (those which have a name) and also
632 to all others (by their internal number).
634 SRM is something like a BIOS for Alpha machines. There are some
635 other such BIOSes, like AlphaBIOS, which this driver cannot
636 support (hey, that's not SRM!).
638 Despite the fact that this driver doesn't work on all Alphas (but
639 only on those which have SRM as their firmware), it's save to
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
