An automatic consistency check of the file systems takes place, and unless this fails, the system comes up to multi-user operation. The proper way to shut the system down is with the .Xr shutdown 8 command. .Pp If the system crashes, it will enter the kernel debugger, .Xr ddb 8 , if it is configured in the kernel. If the crash occurred during initialization and the debugger is not present or is exited, the kernel will halt the system. If the crash occurred during normal operation and the debugger is not present or is exited, the system will attempt a dump to the configured dump device (which will be automatically recovered with .Xr savecore 8 during the next boot cycle), and after the dump is complete (successful or not) the kernel will attempt a reboot. .\" XXX .Pp .\" XXX .Ss Use of SRM Console .\" XXX .Pp .\" XXX console is used to bootstrap system .\" XXX .Pp .\" XXX boot flags, boot file .\" XXX .Pp .\" XXX console device names .\" XXX .Pp .\" XXX .Ss Console Behavior at Power-on, Halt, and Reboot .\" XXX .Pp .\" XXX auto_action variable .\" XXX .Pp .\" XXX .Ss System Bootstrapping Procedure .\" XXX .Pp .\" XXX boot environment .\" XXX .Pp .\" XXX primary/secondary vs. unified bootstrap .Sh FILES .Bl -tag -width /usr/mdec/bootxx_cd9660 -compact .It Pa /netbsd default system kernel .It Pa /usr/mdec/bootxx_cd9660 primary bootstrap for .Dq cd9660 (ISO 9660) file system .It Pa /usr/mdec/bootxx_ffs primary bootstrap for .Dq ffs file system (Berkeley Fast File System) .It Pa /usr/mdec/boot secondary bootstrap .It Pa /usr/mdec/netboot network bootstrap .It Pa /usr/mdec/ustarboot .Dq ustar disk and tape bootstrap .It Pa /boot secondary bootstrap (installed) .El .Sh SEE ALSO .Xr ddb 4 , .Xr savecore 8 , .Xr shutdown 8 , .Xr installboot 8 , .Xr mkbootimage 8 , .Xr setnetbootinfo 8 .Rs .%T "Alpha Architecture Reference Manual Third Edition" .%Q "Alpha Architecture Committee" .%I "Digital Press" .%D 1998 .Re .Sh BUGS The device names used by .Nx Ns Tn /alpha and the .Tn SRM Console often have no relation to each other.
