.Sh DESCRIPTION
|
|
.Sy Power fail and crash recovery.
|
|
Normally, the system will reboot itself at power-up or after crashes.
|
|
An automatic consistency check of the file systems will be performed
|
|
as described in
|
|
.Xr fsck 8 .
|
|
and unless this fails, the system will resume multi-user operations.
|
|
.Pp
|
|
.Sy Cold starts
|
|
A disk-boot program (/usr/mdec/ufsboot) will attempt to load
|
|
.Pa netbsd
|
|
from partition A of the boot device,
|
|
which must currently be an ``sd'' disk.
|
|
Alternatively, network boot program (/usr/mdec/netboot) will load
|
|
.Pa netbsd
|
|
from the NFS root as determined by the procedure described in
|
|
.Xr diskless 8 .
|
|
.Pp
|
|
The
|
|
.Op Fl s
|
|
flag to the boot loader will bring the system up in single-user mode.
|
|
The
|
|
.Op Fl a
|
|
flag instructs the system to prompt for the location of the root filesystem
|
|
and the primary swap partition.
|
|
The
|
|
.Op Fl d
|
|
flag to the boot loader will bring the system up in debug mode.
|
|
Here it waits for a kernel debugger connect; see
|
|
.Xr ddb 4 .
|
|
Any extra flags or arguments, the after the -- separator,
|
|
.Ar <boot string>
|
|
are passed to the boot prom.
|
|
Other flags are currently ignored.
|
|
.Pp
|
|
At any time you can break back to the rom by pressing the `L1' and `a'
|
|
keys at the same time (if the console is a serial port the same is
|
|
achieved by sending a `break').
|
|
If you do this accidentally you can continue whatever was in progress
|
|
by typing `c' followed by the return key.
