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

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

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

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