| from an SRM console; say Y here in order to do that. Note that you |

| help |
| If you enable this option, a subdirectory inside /proc called |
| /proc/srm_environment will give you access to the all important |
| SRM environment variables (those which have a name) and also |
| to all others (by their internal number). |
| |
| SRM is something like a BIOS for Alpha machines. There are some |
| other such BIOSes, like AlphaBIOS, which this driver cannot |
| support (hey, that's not SRM!). |
| |
| Despite the fact that this driver doesn't work on all Alphas (but |
| only on those which have SRM as their firmware), it's save to |
| build it even if your particular machine doesn't know about SRM |
| (or if you intend to compile a generic kernel). It will simply |
| not create those subdirectory in /proc (and give you some warning, |
| of course). |
| |
| This driver is also available as a module and will be called |
| srm_env then. |
