458 There are two different types of booting firmware on Alphas: SRM,
459 which is command line driven, and ARC, which uses menus and arrow
460 keys. Details about the Linux/Alpha booting process are contained in
461 the Linux/Alpha FAQ, accessible on the WWW from
462 <http://www.alphalinux.org/>.
463
464 The usual way to load Linux on an Alpha machine is to use MILO
465 (a bootloader that lets you pass command line parameters to the
466 kernel just like lilo does for the x86 architecture) which can be
467 loaded either from ARC or can be installed directly as a permanent
468 firmware replacement from floppy (which requires changing a certain
469 jumper on the motherboard). If you want to do either of these, say N
470 here. If MILO doesn't work on your system (true for Jensen
471 motherboards), you can bypass it altogether and boot Linux directly
472 from an SRM console; say Y here in order to do that. Note that you
473 won't be able to boot from an IDE disk using SRM.

489

540 as to be laughable. However, there are certain applications (such
541 as benchmark-grade in-kernel web serving) that can make use of as
542 much vmalloc space as is available.
543
544 Say N unless you know you need gobs and gobs of vmalloc space.

546config VERBOSE_MCHECK
547 bool "Verbose Machine Checks"
548
549config VERBOSE_MCHECK_ON
550 int "Verbose Printing Mode (0=off, 1=on, 2=all)"
551 depends on VERBOSE_MCHECK
552 default 1
553 ---help---
554 This option allows the default printing mode to be set, and then
555 possibly overridden by a boot command argument.
556
557 For example, if one wanted the option of printing verbose
558 machine checks, but wanted the default to be as if verbose
559 machine check printing was turned off, then one would choose
560 the printing mode to be 0. Then, upon reboot, one could add
561 the boot command line "verbose_mcheck=1" to get the normal
562 verbose machine check printing, or "verbose_mcheck=2" to get
563 the maximum information available.
564
565 Take the default (1) unless you want more control or more info.

572config SRM_ENV
573 tristate "SRM environment through procfs"
574 depends on PROC_FS
575 ---help---
576 If you enable this option, a subdirectory inside /proc called
577 /proc/srm_environment will give you access to the all important
578 SRM environment variables (those which have a name) and also
579 to all others (by their internal number).
580
581 SRM is something like a BIOS for Alpha machines. There are some
582 other such BIOSes, like AlphaBIOS, which this driver cannot
583 support (hey, that's not SRM!).
584
585 Despite the fact that this driver doesn't work on all Alphas (but
586 only on those which have SRM as their firmware), it's save to
587 build it even if your particular machine doesn't know about SRM
588 (or if you intend to compile a generic kernel). It will simply
589 not create those subdirectory in /proc (and give you some warning,
590 of course).
591
592 This driver is also available as a module and will be called
593 srm_env then.
