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

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

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

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