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

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.

501 If unsure, say N.

566config ALPHA_LARGE_VMALLOC
567 bool
568 ---help---
569 Process creation and other aspects of virtual memory management can
570 be streamlined if we restrict the kernel to one PGD for all vmalloc
571 allocations. This equates to about 8GB.
572
573 Under normal circumstances, this is so far and above what is needed
574 as to be laughable. However, there are certain applications (such
575 as benchmark-grade in-kernel web serving) that can make use of as
576 much vmalloc space as is available.
577
578 Say N unless you know you need gobs and gobs of vmalloc space.

587 ---help---
588 This option allows the default printing mode to be set, and then
589 possibly overridden by a boot command argument.
590
591 For example, if one wanted the option of printing verbose
592 machine checks, but wanted the default to be as if verbose
593 machine check printing was turned off, then one would choose
594 the printing mode to be 0. Then, upon reboot, one could add
595 the boot command line "verbose_mcheck=1" to get the normal
596 verbose machine check printing, or "verbose_mcheck=2" to get
597 the maximum information available.
598
599 Take the default (1) unless you want more control or more info.

609 ---help---
610 If you enable this option, a subdirectory inside /proc called
611 /proc/srm_environment will give you access to the all important
612 SRM environment variables (those which have a name) and also
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.
