88 run on any supported Alpha system. However, if you configure a
89 kernel for your specific system, it will be faster and smaller.

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

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

589 as to be laughable. However, there are certain applications (such

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