	  firmware replacement from floppy (which requires changing a certain
	  jumper on the motherboard). If you want to do either of these, say N
	  here. If MILO doesn't work on your system (true for Jensen
	  motherboards), you can bypass it altogether and boot Linux directly
	  from an SRM console; say Y here in order to do that. Note that you
	  won't be able to boot from an IDE disk using SRM.

	  If unsure, say N.

	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,

	  will run faster if you say N here.

	  See also the <file:Documentation/smp.txt>, and the SMP-HOWTO
	  available at <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

# LARGE_VMALLOC is racy, if you *really* need it then fix it first
config ALPHA_LARGE_VMALLOC
	bool
	---help---
	  Process creation and other aspects of virtual memory management can
	  be streamlined if we restrict the kernel to one PGD for all vmalloc
	  allocations.  This equates to about 8GB.

	  Under normal circumstances, this is so far and above what is needed
	  as to be laughable.  However, there are certain applications (such
	  as benchmark-grade in-kernel web serving) that can make use of as
	  much vmalloc space as is available.

	  Say N unless you know you need gobs and gobs of vmalloc space.

	  This option allows the default printing mode to be set, and then
	  possibly overridden by a boot command argument.

	  For example, if one wanted the option of printing verbose
	  machine checks, but wanted the default to be as if verbose
	  machine check printing was turned off, then one would choose
	  the printing mode to be 0. Then, upon reboot, one could add
	  the boot command line "verbose_mcheck=1" to get the normal
	  verbose machine check printing, or "verbose_mcheck=2" to get
	  the maximum information available.

	  Take the default (1) unless you want more control or more info.

config SRM_ENV

	  If you enable this option, a subdirectory inside /proc called
	  /proc/srm_environment will give you access to the all important
	  SRM environment variables (those which have a name) and also
	  to all others (by their internal number).

	  SRM is something like a BIOS for Alpha machines. There are some
	  other such BIOSes, like AlphaBIOS, which this driver cannot
	  support (hey, that's not SRM!).

	  Despite the fact that this driver doesn't work on all Alphas (but
	  only on those which have SRM as their firmware), it's save to
	  build it even if your particular machine doesn't know about SRM
	  (or if you intend to compile a generic kernel). It will simply
	  not create those subdirectory in /proc (and give you some warning,
	  of course).

	  This driver is also available as a module and will be called
	  srm_env then.
