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/>.
497
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.
508
509 If unsure, say N.

606 machine check printing was turned off, then one would choose
607 the printing mode to be 0. Then, upon reboot, one could add

609 verbose machine check printing, or "verbose_mcheck=2" to get

633 SRM is something like a BIOS for Alpha machines. There are some
634 other such BIOSes, like AlphaBIOS, which this driver cannot
635 support (hey, that's not SRM!).
636
637 Despite the fact that this driver doesn't work on all Alphas (but
638 only on those which have SRM as their firmware), it's save to
639 build it even if your particular machine doesn't know about SRM
640 (or if you intend to compile a generic kernel). It will simply
641 not create those subdirectory in /proc (and give you some warning,
642 of course).
643
644 This driver is also available as a module and will be called
645 srm_env then.
