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
|
|
<http://www.alphalinux.org/>.
|
|
|
|
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.

---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.

---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.

---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.
