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

526 If you say N here, the kernel will run on single and multiprocessor

528 you say Y here, the kernel will run on many, but not all,
529 singleprocessor machines. On a singleprocessor machine, the kernel
530 will run faster if you say N here.

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