.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
|
|
The SPARC system currently uses the SunOS bootstrap loaders.
|
|
This will be changed in a future version of the system.
|
|
The SunOS boot will attempt to load
|
|
.Pa netbsd
|
|
from partition A of the boot device,
|
|
which must currently be an ``sd'' disk.
|
|
.Pp
|
|
The
|
|
.Op Fl s
|
|
flag to the SunOS boot loader will being 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 SunOS boot loader will bring the system up in debug mode.
|
|
.\"Here it waits for a kernel debugger connect; see
|
|
.\".Xr kgdb 8 .
|
|
Other flags are currently ignored.
|
|
.Pp
|
|
The Sparc boot rom comes in two flavours: an ``old-style'' rom is used in
|
|
sun4 machines, while A ``new-style'' rom can be found on sun4c and sun4m models.
|
|
The ``new-style'' Sparc boot rom is a full-featured Forth system with emacs
|
|
key bindings. It can be put in ``old-style'' user-interface compatibility
|
|
mode (in which case it shows a simple `>' prompt), but this is essentially
|
|
useless. However, by default the rom runs in old-mode; to enter new-mode type `n'.
|
|
The rom then shows a Forth-style `ok' prompt. It is recommended to have
|
|
the rom always start in its native ``new-style'' mode. Utter the following
|
|
incantation in new-mode to force the rom to always start in new-mode.
|
|
.Pp
|
|
.Pa \ ok
|
|
setenv sunmon-compat? false
|
|
.Pp
|
|
The rom will normally load the kernel from "sd(0,0,0)vmunix". To change the
|
|
default so that
|
|
.Pa NetBSD
|
|
will be loaded type the following
|
|
.Pp
|
|
.Pa \ ok
|
|
setenv boot-from sd(0,0,0)netbsd
|
|
.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 `go'.

.Sh BUGS
|
|
The use of Sun disk labels, without the ability to write them,
|
|
is problematic.
