BOOT.CONFIG(5)		    BSD	File Formats Manual		BOOT.CONFIG(5)

NAME
     boot.config -- Configuration file for the boot blocks

DESCRIPTION
     The boot.config file contains options for the FreeBSD boot	block code.

     When the FreeBSD boot loader runs,	it searches the	"a" slice of the boot
     partition for a boot.config file (as a result, slices which are missing
     an	"a" partition require user intervention	during the boot	process).  If
     the boot.config file is found, its	contents are used as the default con-
     figuration	options	for the	boot block code	and are	echoed to the system
     console.

     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
     boot(8) option on a single	line, as it is done at the "boot:" prompt.

     The options related to the	boot image selection described below and all
     the other options available for boot.config are documented	in detail in
     the boot(8) manual	page.

FILES
     /boot.config  parameters for the boot blocks (optional)

EXAMPLES
     The command:

	   # echo "-P" > /boot.config

     will activate the serial console of FreeBSD.

     The command:

	   # echo "1:ad(1,a)/boot/loader" > /boot.config

     will instruct the second stage of boot(8) on the first disk to boot with
     the third boot(8) stage from the second disk.

     The command:

	   # echo "1:ad(1,a)/boot/loader -P" > /boot.config

     will do both of the above.
