488 There are two different types of booting firmware on Alphas: SRM,
489 which is command line driven, and ARC, which uses menus and arrow

491 the Linux/Alpha FAQ, accessible on the WWW from
492 <http://www.alphalinux.org/>.
493
494 The usual way to load Linux on an Alpha machine is to use MILO
495 (a bootloader that lets you pass command line parameters to the
496 kernel just like lilo does for the x86 architecture) which can be
497 loaded either from ARC or can be installed directly as a permanent
498 firmware replacement from floppy (which requires changing a certain
499 jumper on the motherboard). If you want to do either of these, say N
500 here. If MILO doesn't work on your system (true for Jensen
501 motherboards), you can bypass it altogether and boot Linux directly
502 from an SRM console; say Y here in order to do that. Note that you
503 won't be able to boot from an IDE disk using SRM.
504
505 If unsure, say N.

571 bool
572 ---help---
573 Process creation and other aspects of virtual memory management can
574 be streamlined if we restrict the kernel to one PGD for all vmalloc
575 allocations. This equates to about 8GB.
576
577 Under normal circumstances, this is so far and above what is needed
578 as to be laughable. However, there are certain applications (such
579 as benchmark-grade in-kernel web serving) that can make use of as
580 much vmalloc space as is available.
581
582 Say N unless you know you need gobs and gobs of vmalloc space.

591 ---help---
592 This option allows the default printing mode to be set, and then
593 possibly overridden by a boot command argument.
594
595 For example, if one wanted the option of printing verbose
596 machine checks, but wanted the default to be as if verbose
597 machine check printing was turned off, then one would choose
598 the printing mode to be 0. Then, upon reboot, one could add
599 the boot command line "verbose_mcheck=1" to get the normal
600 verbose machine check printing, or "verbose_mcheck=2" to get
601 the maximum information available.
602
603 Take the default (1) unless you want more control or more info.

613 ---help---
614 If you enable this option, a subdirectory inside /proc called
615 /proc/srm_environment will give you access to the all important
616 SRM environment variables (those which have a name) and also
617 to all others (by their internal number).
618
619 SRM is something like a BIOS for Alpha machines. There are some
620 other such BIOSes, like AlphaBIOS, which this driver cannot
621 support (hey, that's not SRM!).
622
623 Despite the fact that this driver doesn't work on all Alphas (but
624 only on those which have SRM as their firmware), it's save to
625 build it even if your particular machine doesn't know about SRM
626 (or if you intend to compile a generic kernel). It will simply
627 not create those subdirectory in /proc (and give you some warning,
628 of course).
629
630 This driver is also available as a module and will be called
631 srm_env then.
