502 loaded either from ARC or can be installed directly as a permanent

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.

586 Under normal circumstances, this is so far and above what is needed

601 This option allows the default printing mode to be set, and then

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.
611

626 to all others (by their internal number).
627
628 SRM is something like a BIOS for Alpha machines. There are some
629 other such BIOSes, like AlphaBIOS, which this driver cannot
630 support (hey, that's not SRM!).
631
632 Despite the fact that this driver doesn't work on all Alphas (but
633 only on those which have SRM as their firmware), it's save to
634 build it even if your particular machine doesn't know about SRM
635 (or if you intend to compile a generic kernel). It will simply
636 not create those subdirectory in /proc (and give you some warning,
637 of course).
638
639 This driver is also available as a module and will be called
640 srm_env then.
