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

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

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