The path used for automatic booting is +.Nm /netbsd , +but it can be overridden in the optional file +.Nm /boot.config +stored in the root of the disk filesystem. The user can also type a different filename and a combination of boot options. +.Sh BeSquare BEE3 +On this system there is no local disk and booting over the network is the only option. +Network boot can also be explicitly selected by hitting +.Nm f +at the boot loader prompt. +.Sh KERNEL ARGUMENTS +At the boot loader prompt, the user may boot +.Nx +with a number of options that are passed to the kernel unmodified. Parsing of these options is +defined in the file +.Nm /sys/boot_flag.h +Some additional flags are as follows. +.Bl -tag -width xxx -offset indent +.It Li e +Empty -- this argument requests +.Nx +to ignore all symbolic information and empty its initial symbol table. +.It Li n +Name -- Prompt for the root file system device, the system crash dump +device, and the path to +.Xr init 8 . +.It Li N +NoName -- Do not prompt for the root file system device, the system crash dump +device, and the path to +.Xr init 8 . +If the configured-in devices are present, use them. +.It Li s +Single -- Boot only to single-user mode. +.El +.Sh SEE ALSO +.Xr ddb 4 , +.Xr halt 8 , +.Xr init 8 , +.Xr installboot 8 , +.Xr rc 8 , +.Xr reboot 8 , +.Xr savecore 8 , +.Xr shutdown 8 +.Sh HISTORY +The +.Nm +command is +.Ud . |
