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

534 you have a system with more than one CPU, say Y.
536 If you say N here, the kernel will run on single and multiprocessor
537 machines, but will use only one CPU of a multiprocessor machine. If
538 you say Y here, the kernel will run on many, but not all,
539 singleprocessor machines. On a singleprocessor machine, the kernel
540 will run faster if you say N here.

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

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