          There are two different types of booting firmware on Alphas: SRM,

          which is command line driven, and ARC, which uses menus and arrow

          keys. Details about the Linux/Alpha booting process are contained in

          the Linux/Alpha FAQ, accessible on the WWW from

          .

          The usual way to load Linux on an Alpha machine is to use MILO

          (a bootloader that lets you pass command line parameters to the

          kernel just like lilo does for the x86 architecture) which can be

          loaded either from ARC or can be installed directly as a permanent

          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.

          This enables support for systems with more than one CPU. If you have

          a system with only one CPU, like most personal computers, say N. If

          you have a system with more than one CPU, say Y.

          If you say N here, the kernel will run on single and multiprocessor

          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,

          singleprocessor machines. On a singleprocessor machine, the kernel

          will run faster if you say N here.

          See also the , and the SMP-HOWTO

          available at .

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

          Say Y to support efficient handling of discontiguous physical memory,

          for architectures which are either NUMA (Non-Uniform Memory Access)

          or have huge holes in the physical address space for other reasons.

        help

          Say Y to compile the kernel to support NUMA (Non-Uniform Memory

          Access).  This option is for configuring high-end multiprocessor

          server machines.  If in doubt, say N.

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.

config VERBOSE_MCHECK

        depends on VERBOSE_MCHECK

        default 1

        ---help---

          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

        tristate "SRM environment through procfs"

        depends on PROC_FS

        ---help---

          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.
