.Dt BOOT.CONFIG 5
|
|
.Os
|
|
.Sh NAME
|
|
.Nm boot.config
|
|
.Nd "Configuration file for the boot blocks"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file contains options for the
|
|
.Fx
|
|
boot block code.
|
|
.Pp
|
|
When the
|
|
.Fx
|
|
boot loader runs, it searches the
|
|
.Dq Li a
|
|
slice of the boot partition for a
|
|
.Nm
|
|
file (as a result, slices which are missing an
|
|
.Dq Li a
|
|
partition require user intervention during the boot process).
|
|
If the
|
|
.Nm
|
|
file is found, its contents are used as the default configuration
|
|
options for the boot block code and are echoed to the system console.
|
|
.Pp
|
|
A valid format of this file is to put BIOS drive number, a controller
|
|
type, a unit number, a partition, a kernel file name, and any other
|
|
valid
|
|
.Xr boot 8
|
|
option on a single line, as it is done at the
|
|
.Dq Li "boot:"
|
|
prompt.
|
|
.Pp
|
|
The options related to the boot image selection described below and all
|
|
the other options available for
|
|
.Nm
|
|
are documented in detail in the
|
|
.Xr boot 8
|
|
manual page.
|
|
