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

526 you have a system with more than one CPU, say Y.
528 If you say N here, the kernel will run on single and multiprocessor

530 you say Y here, the kernel will run on many, but not all,
531 singleprocessor machines. On a singleprocessor machine, the kernel

604 For example, if one wanted the option of printing verbose
605 machine checks, but wanted the default to be as if verbose
606 machine check printing was turned off, then one would choose
607 the printing mode to be 0. Then, upon reboot, one could add
608 the boot command line "verbose_mcheck=1" to get the normal
609 verbose machine check printing, or "verbose_mcheck=2" to get
610 the maximum information available.
