496 There are two different types of booting firmware on Alphas: SRM,
497 which is command line driven, and ARC, which uses menus and arrow
498 keys. Details about the Linux/Alpha booting process are contained in
499 the Linux/Alpha FAQ, accessible on the WWW from
500 <http://www.alphalinux.org/>.
502 The usual way to load Linux on an Alpha machine is to use MILO
503 (a bootloader that lets you pass command line parameters to the
504 kernel just like lilo does for the x86 architecture) which can be
505 loaded either from ARC or can be installed directly as a permanent
506 firmware replacement from floppy (which requires changing a certain
507 jumper on the motherboard). If you want to do either of these, say N
508 here. If MILO doesn't work on your system (true for Jensen
509 motherboards), you can bypass it altogether and boot Linux directly
510 from an SRM console; say Y here in order to do that. Note that you
511 won't be able to boot from an IDE disk using SRM.

528 This enables support for systems with more than one CPU. If you have
529 a system with only one CPU, like most personal computers, say N. If
530 you have a system with more than one CPU, say Y.
532 If you say N here, the kernel will run on single and multiprocessor
533 machines, but will use only one CPU of a multiprocessor machine. If
534 you say Y here, the kernel will run on many, but not all,
535 singleprocessor machines. On a singleprocessor machine, the kernel
536 will run faster if you say N here.

591 as to be laughable. However, there are certain applications (such
592 as benchmark-grade in-kernel web serving) that can make use of as

605 This option allows the default printing mode to be set, and then
606 possibly overridden by a boot command argument.
608 For example, if one wanted the option of printing verbose
609 machine checks, but wanted the default to be as if verbose
610 machine check printing was turned off, then one would choose
611 the printing mode to be 0. Then, upon reboot, one could add
612 the boot command line "verbose_mcheck=1" to get the normal
613 verbose machine check printing, or "verbose_mcheck=2" to get
614 the maximum information available.
616 Take the default (1) unless you want more control or more info.
