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

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

591 depends on DISCONTIGMEM && BROKEN

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

630 Process creation and other aspects of virtual memory management can

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

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