497 There are two different types of booting firmware on Alphas: SRM,
498 which is command line driven, and ARC, which uses menus and arrow
499 keys. Details about the Linux/Alpha booting process are contained in
500 the Linux/Alpha FAQ, accessible on the WWW from
501 <http://www.alphalinux.org/>.
502
503 The usual way to load Linux on an Alpha machine is to use MILO
504 (a bootloader that lets you pass command line parameters to the
505 kernel just like lilo does for the x86 architecture) which can be
506 loaded either from ARC or can be installed directly as a permanent
507 firmware replacement from floppy (which requires changing a certain
508 jumper on the motherboard). If you want to do either of these, say N
509 here. If MILO doesn't work on your system (true for Jensen
510 motherboards), you can bypass it altogether and boot Linux directly
511 from an SRM console; say Y here in order to do that. Note that you
512 won't be able to boot from an IDE disk using SRM.
513
514 If unsure, say N.

529 This enables support for systems with more than one CPU. If you have
530 a system with only one CPU, like most personal computers, say N. If
531 you have a system with more than one CPU, say Y.
532
533 If you say N here, the kernel will run on single and multiprocessor
534 machines, but will use only one CPU of a multiprocessor machine. If
535 you say Y here, the kernel will run on many, but not all,
536 singleprocessor machines. On a singleprocessor machine, the kernel
537 will run faster if you say N here.

585 bool
586 ---help---
587 Process creation and other aspects of virtual memory management can
588 be streamlined if we restrict the kernel to one PGD for all vmalloc
589 allocations. This equates to about 8GB.
590
591 Under normal circumstances, this is so far and above what is needed
592 as to be laughable. However, there are certain applications (such
593 as benchmark-grade in-kernel web serving) that can make use of as
594 much vmalloc space as is available.

606 This option allows the default printing mode to be set, and then
607 possibly overridden by a boot command argument.
608
609 For example, if one wanted the option of printing verbose
610 machine checks, but wanted the default to be as if verbose
611 machine check printing was turned off, then one would choose
612 the printing mode to be 0. Then, upon reboot, one could add
613 the boot command line "verbose_mcheck=1" to get the normal
614 verbose machine check printing, or "verbose_mcheck=2" to get
615 the maximum information available.
616
617 Take the default (1) unless you want more control or more info.

632 ---help---
633 If you enable this option, a subdirectory inside /proc called
634 /proc/srm_environment will give you access to the all important
635 SRM environment variables (those which have a name) and also
636 to all others (by their internal number).
637
638 SRM is something like a BIOS for Alpha machines. There are some
639 other such BIOSes, like AlphaBIOS, which this driver cannot
640 support (hey, that's not SRM!).
641
642 Despite the fact that this driver doesn't work on all Alphas (but
643 only on those which have SRM as their firmware), it's save to
644 build it even if your particular machine doesn't know about SRM
645 (or if you intend to compile a generic kernel). It will simply
646 not create those subdirectory in /proc (and give you some warning,
647 of course).
648
649 This driver is also available as a module and will be called
650 srm_env then.
