.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,
|
|
and unless this fails, the system will resume multi-user operations.
|
|
.Pp
|
|
.Sy Cold starts.
|
|
These are processor-type dependent.
|
|
On the
|
|
.Tn CCI
|
|
Power 6/32 and related processors,
|
|
the system will do a standard autoboot from drive 0
|
|
upon power-up or reset.
|
|
This automatic boot may be cancelled by typing a
|
|
.Ql \&#
|
|
in the first few seconds after reset.
|
|
This enters console mode; the console prompt is
|
|
.Ql >
|
|
or
|
|
.Ql \&# .
|
|
The boot flags can be set to any hexadecimal value
|
|
.Fl n
|
|
with the command
|
|
.Pp
|
|
.Bd -filled -offset indent -compact
|
|
.Li \&#> p23
|
|
.Ar n .
|
|
.Ed
|
|
.Pp
|
|
The default device may be examined or set; see the Diagnostics and Debugging
|
|
manual for the processor for details on device naming and syntax.
|
|
After setting the boot flags and/or device,
|
|
a bootstrap sequence can be initiated with
|
|
.Pp
|
|
.Dl #> fb
|
|
.Pp
|
|
A specific device or bootstrap file may be used; for example,
|
|
.Pp
|
|
.Dl \&#> \&fb xfd(1,0)
|
|
.Pp
|
|
would boot from the `a' partition on
|
|
.Tn XFD
|
|
drive 1.
|
|
.Pp
|
|
The file specifications used for the boostrap
|
|
when loaded with the
|
|
.Dq askme
|
|
flag
|
|
(register 23 set to 1 or 3)
|
|
are of the form:
|
|
.Pp
|
|
.Dl device(adaptor,controller,unit,minor)
|
|
.Pp
|
|
where
|
|
.Ar device
|
|
is the type of the device to be searched,
|
|
.Ar adaptor
|
|
is number of the
|
|
.Tn VERSAbus
|
|
(or
|
|
.Tn VMEbus )
|
|
to which the device is attached,
|
|
.Ar controller
|
|
is the unit number of the controller on that buss,
|
|
.Ar unit
|
|
is the unit number of the disk or tape,
|
|
and
|
|
.Ar minor
|
|
is the disk partition or tape file number.
|
|
Leading adaptor or controller numbers default to 0.
|
|
Normal line editing characters can be used when typing the file specification.
|
|
The following list of supported devices may vary from installation to
|
|
installation:
|
|
.Pp
|
|
.Bd -unfilled -offset indent -compact
|
|
dk SMD or ESDI disks on VDDC or SMD-E
|
|
cy tape on Ciprico Tapemaster controller
|
|
.Ed
|
|
.Pp
|
|
For example,
|
|
to boot from a file system which starts at cylinder 0
|
|
of unit 0 of an
|
|
.Tn SMD-E
|
|
disk, type
|
|
.Ql dk(0,0)kernel
|
|
to the boot prompt;
|
|
.Ql dk(2,1,0)kernel
|
|
would specify drive 1 on
|
|
.Tn SMD-E
|
|
controller 2.
|
|
.Pp
|
|
In an emergency, the bootstrap methods described in the paper
|
|
.%T "Installing and Operating 4.3 BSD-tahoe UNIX on the Tahoe"
|
|
can be used
|
|
to boot from a distribution tape.

The disklabel format used by some versions of the console processor
|
|
is different than the format used by

|
.Tn UNIX
|
|
and the bootstrap.
