515 There are two different types of booting firmware on Alphas: SRM,
516 which is command line driven, and ARC, which uses menus and arrow
517 keys. Details about the Linux/Alpha booting process are contained in
518 the Linux/Alpha FAQ, accessible on the WWW from
519 <http://www.alphalinux.org/>.
521 The usual way to load Linux on an Alpha machine is to use MILO
522 (a bootloader that lets you pass command line parameters to the
523 kernel just like lilo does for the x86 architecture) which can be
524 loaded either from ARC or can be installed directly as a permanent
525 firmware replacement from floppy (which requires changing a certain
526 jumper on the motherboard). If you want to do either of these, say N
527 here. If MILO doesn't work on your system (true for Jensen
528 motherboards), you can bypass it altogether and boot Linux directly
529 from an SRM console; say Y here in order to do that. Note that you
530 won't be able to boot from an IDE disk using SRM.

546 This enables support for systems with more than one CPU. If you have
547 a system with only one CPU, say N. If you have a system with more
550 If you say N here, the kernel will run on uni- and multiprocessor
551 machines, but will use only one CPU of a multiprocessor machine. If
552 you say Y here, the kernel will run on many, but not all,
553 uniprocessor machines. On a uniprocessor machine, the kernel
554 will run faster if you say N here.

588 depends on DISCONTIGMEM && BROKEN

601 The Wait for Interrupt (WTINT) PALcall attempts to place the CPU
602 to sleep until the next interrupt. This may reduce the power
603 consumed, and the heat produced by the computer. However, it has
604 the side effect of making the cycle counter unreliable as a timing
605 device across the sleep.
607 For emulation under QEMU, definitely say Y here, as we have other
608 mechanisms for measuring time than the cycle counter.
610 For EV4 (but not LCA), EV5 and EV56 systems, or for systems running
611 MILO, sleep mode is not supported so you might as well say N here.
613 For SMP systems we cannot use the cycle counter for timing anyway,

627 Process creation and other aspects of virtual memory management can

629 allocations. This equates to about 8GB.
631 Under normal circumstances, this is so far and above what is needed
632 as to be laughable. However, there are certain applications (such
633 as benchmark-grade in-kernel web serving) that can make use of as
634 much vmalloc space as is available.

643 depends on VERBOSE_MCHECK
646 This option allows the default printing mode to be set, and then
647 possibly overridden by a boot command argument.
649 For example, if one wanted the option of printing verbose
650 machine checks, but wanted the default to be as if verbose
651 machine check printing was turned off, then one would choose
652 the printing mode to be 0. Then, upon reboot, one could add
653 the boot command line "verbose_mcheck=1" to get the normal
654 verbose machine check printing, or "verbose_mcheck=2" to get
655 the maximum information available.
657 Take the default (1) unless you want more control or more info.

666 minimizes latency, whereas a low frequency minimizes overhead of
667 process accounting. The later effect is especially significant
668 when being run under QEMU.

715 only on those which have SRM as their firmware), it's save to
