507 There are two different types of booting firmware on Alphas: SRM,
508 which is command line driven, and ARC, which uses menus and arrow
509 keys. Details about the Linux/Alpha booting process are contained in
510 the Linux/Alpha FAQ, accessible on the WWW from
511 <http://www.alphalinux.org/>.
512
513 The usual way to load Linux on an Alpha machine is to use MILO
514 (a bootloader that lets you pass command line parameters to the
515 kernel just like lilo does for the x86 architecture) which can be
516 loaded either from ARC or can be installed directly as a permanent
517 firmware replacement from floppy (which requires changing a certain
518 jumper on the motherboard). If you want to do either of these, say N
519 here. If MILO doesn't work on your system (true for Jensen
520 motherboards), you can bypass it altogether and boot Linux directly
521 from an SRM console; say Y here in order to do that. Note that you
522 won't be able to boot from an IDE disk using SRM.
523
524 If unsure, say N.

621 machine check printing was turned off, then one would choose

648 SRM is something like a BIOS for Alpha machines. There are some
649 other such BIOSes, like AlphaBIOS, which this driver cannot
650 support (hey, that's not SRM!).
651
652 Despite the fact that this driver doesn't work on all Alphas (but
653 only on those which have SRM as their firmware), it's save to
654 build it even if your particular machine doesn't know about SRM
655 (or if you intend to compile a generic kernel). It will simply
656 not create those subdirectory in /proc (and give you some warning,
657 of course).
658
659 This driver is also available as a module and will be called
660 srm_env then.
